As a retired mechanic, you're very good at instructing and covering a topic thoroughly. I've used the ATF Acetone mix for over 30 years, and swear by it. It is the best penetrant
+iceman22st I agree. I was using PB Blaster for the longest time. Had a stubborn bolt so I did some research. I found the study Chris showed in his video so I made my own 50/50 ATF and Acetone mixture. Worked great, been using it ever since.
Wish I had this 5 years ago. It took me 12 applications of WD40, 10 hours, 5 knuckle scrapes, 7 cuts, 4 bruises, and 1.5 pints of blood, sweat and tears to loosen the bolts on my EGR valve that I later found out didn't need to be replaced
BlueMacGyver I didn't look on the internet and that's my point. I went off the information given to me by a professional ASE certified automotive technician that my EGR valve needed to be replaced when it was actually only a sensor. If I had done my own research (like I do now), I would have realized this and saved a lot of time and money.
This really does work great. I recently was bleeding the brakes on a 1997 Chevy 1500, and since I'm fairly sure they were the original calipers and brake cylinders I didn't have much confidence the bleeders would come loose. I put a little of this on them, let it sit for awhile, and they opened right up. A tip is to make sure you get your own acetone. My wife wasn't very happy that I stole her nail polish remover.
Marissa Calcione This is not meant for battery terminals (unless they are stuck and you are trying to remove them). You can use WD40 and that works decently. You can also use silcone spray which works great or Vaseline. Just put a thin coat.
Hey Chris. I just used your Acetone/ATF fluid mix on my 15 year old Altima's control arm body mount bolts. Worked awesome. I let it sit for a weekend and it did the job. I'm in Toronto and we heavily salt and brine our winter roads. Had my torch standing by, but wasn't needed. Thanks for all the great videos. Saved my bacon many times. Stay safe.
+Andrew Peters, I cannot reply to your comment for some reason so I hope you see this. I would get a car polish or some type of scratch remover polish and use that. Toothpaste can damage your paint if you use the wrong type. Dont use WD40 either. If you want to try something before you go out to get the polish, try car wax first.
Your dumb the plastic didn't mix from that cup maybe if he waited few MIn and then if put in and even if I did it wouldn't matter it's to remove rusty bolts so not to put in your motor
Hey man, this homemade penetrating oil rocks! I have a wheel suspension joint that was stuck due to rust. Used lots of liquid wrench, hammering, etc. but to no avail. I made up what you said: mix acetone acetone and ATF, spent $8. It was magic!
Thank you, Chris! I love your videos. Straight to the point with no intro, no music - very much appreciated. Project Farm Channel did an in depth review of penetrating oils and the conclusion was that Liquid Wrench was #1, DIY mix with Transmission Fluid 50:50 Acetone was #2, and Kroil came last and was the most expensive. Avoid Kroil. Penetrating Oil is usually a mix of low viscosity (very thin) oil + solvents to degunk old oil and rust. Liquid Wrench does not have Acetone or Toluol (Toluene) which can strip paint and dissolve plastic. The DIY solution has Acetone. When you use this DIY mix on unpainted bare metal it is fine and very effective. Do not use it on any plastic, acrylic, nylon, or painted parts as it will dissolve them. I use penetrating oil for freeing up vintage sewing machines that have seized up due to old baked on oil. I can only use this or carb cleaner on all metal parts not on plastic, or belts, or painted exterior. Viewers please be aware of this constraint.
I mixed motor oil, gas, actone, Pepsi, dish soap, baking soda, embalming fluid, water, orange juice, and ky together. I wasn't making anything just started mixing things.
Didn't think it was possible but this is magic on anything that's rusty. Used it on 20 year old Toyota Tacoma to remove the o2 sensor. I thought that maybe it hadn't been on right but before I sprayed the 2nd o2 sensor, I attempted to remove it and there was absolutely no way it was budging. So I sprayed it waited maybe 10 or 15 minutes and it came right off with no force what so ever. I was blown away I came in all excited telling my girl. No bs I even called my dad. I have used this mix on crescent wrenches, c clamps, I even used it on my hinges off the doors in my house. Works like nothing I've ever seen. I was completely amazed. Never ever ever will I buy e40 or anything similar. Thanks Chris
Thank you, thank you, thank you Chris! Had a stuck spark plug that wouldn’t budge and was afraid of stripping threads on an aluminum head. Put this mixture on and let soak overnight and in the morning BAM, loosened right up!!
Saw this post by accident. One day later I am in the driveway blocking the garage under my car on jack stands with a socket and a cheater bar pulling so hard I'm afraid I'm going to break the socket or pull the car off the jack stands on top of me. Had a very small old time oil-can oiler that was all metal and the ATF from previously working on my Altima. Off to the wife's makeup cabinet for the nail polish remover, its got other chemicals in it besides Acetone. All I have, so I go for it. Mix it up. Put it on the bolt. 3 minutes later, no change, can't get it off. Go back in the house. No Auto Transmission fluid (CVT) in this car, if I can't get this fill plug off the car it gets on a car hauler to the dealer 50 miles away. Uggh. $$$$$. Fifteen minutes later I try again. While I'm trying to put the cheater bar on the socket wrench with almost no pressure the fill plug breaks loose. I take it off with my fingers! It was like magic. I couldn't believe it. I am like an excited kid telling my wife about this. I was skeptical when I saw the post, not anymore. I'll be buying a modern oiler with real rubber to keep the acetone from evaporating. Never wasting money on commercial products again. Nice save, Chris. The wife is happy her car is off the jack stands and in the garage!
do that repitedly, once evaporated in about 8min after the last application, use heat from an open flame (if you have a "jet lighter" the better) and then use your braking bar
I tried this and it does work! My only problem was that I used a cheap Chinese oiler from Advance Auto. The acetone destroyed the pump and fused the paint on the threaded top of the can to the pump section. I could not separate them. I had to toss the entire oiler out. I have bought a new oiler from Amazon. It is a one pint GoldenRod oiler. It was made in the U.S.A. It has no paint on the threads and the filler cap is made of brass. It should work well and last a long time.
Thanks so much for the “knowledge sharing” Chris. I just made the ATF/Acetone solution that you demonstrated in your video and it is working like a charm. It’s plain to see (actually hear, lol) that you’re an intelligent guy with a natural ability for teaching others what you know and understand. Well done and keep up the good work!
You can use generic hydraulic fluid (from jacks, tractors etc) instead of atf. Also, atf and gasoline mixed can be used in a pinch. I've also used staight diesel fuel; its not super effective but can be better than nothing and is also good for cleaning/degresing car parts.
Made some of this stuff this weekend to remove some super rusted spark plugs and it worked like a champ...PB Blaster couldn't do anything (I ended up breaking off one plug before I finally went and bought some acetone), but this home brew really loosened everything up. Good vid. Good channel. Subscribed.
+john smith +nw8000 that's important enough that I'll repeat it, you should never pull plugs out of an engine warm, especially one with aluminum heads. You can usually get away with it with a iron headed engine but you'll mess up an aluminum headed engine. Even if you don't pull the threads out the first time you'll weaken them and they will come out later. This is why there are so many ways out there to put new threads in the spark plug hole of an aluminum headed engine.
From an old man to a young man..... you are a gifted person ....and I admire you and your driving force. Dont screw up and get a big head, respect others unless given a reason not to, stay true to yourself and you will be an assume man till the day you die.
Great video. Been doing this for years, works great. I repair office machinery (copiers, scanners, etc) Copier fusers (heaters) run 350 degrees while copying so the bearings often freeze to the shaft if the previous tech didn't place high temp grease on the shaft prior. Of couse we couldn't use this mixture, but we often use a 50/50 of regent isopropyl and light machine oil. I've used this mixture on some pretty rusted nuts in automotive also. Didn't work as well as the atf/acetone on brake rotor, but it does work well on smaller nuts and doesn't eat plastic. Overall, you can put it in a precision oiler and just dab it on where you need it. Even if you really don't "need" to use it, the job will go faster with less stress on the hardware during the disassemble/reassemble process. Use it constantly.
Thankyou. Your info is golden. Many channels support this formula. Its obviously a winner. The acetone only eats certain plastics. Clearly. I store acetone in used plastic coca cola bottles
omg! Im sure you get this alot but you're a genius! putting lift kit on a jeep cherokee and at my wits end, but as soon as I tried this it was off in a flash! You saved me a hundred bucks in bolts and hours in drilling! thank you so much. sincerely ChrisBreaks... in Oklahoma.
This is great. One other tip. Keep this stuff the hell away from rubber too (brake lines, boots, bushings, tires, etc.). ATF damages rubber. Acetone probably evaporates too quickly to matter. Wipe it off any rubber it gets on at least.
ChrisFix Same here! Your channel rocks. I've watched all Scotty Kilmers vids along with some from Engineering Explained, ETCG, Robinson Auto and Real Fixes Real Fast and yours have a different style which I love. You're a great teacher. Thank you for sharing your knowledge!!!
Thank you for this video. I recently was at menards and stopped in the lube aisle to grab a can of penetrating oil. I saw a 7 oz can of kroil for 26 bucks. I thought to myself you cant be serious. That led me down the path to make my own. Best part was i had both ingredients in my shop already. So I just ordered a metal spray can and now I have a 32 oz can of the stuff and still enough ingredients to make another batch. The days of overpriced penetrating oil are over.
I am here because I saw an ad for a new penetrating oil called "Superzilla". I went to their website and they want $12 for an 8 ounce bottle. What the hell? I will definitely be trying this recipe. Thumbs up and thank you ChrisFix.
A theory after reading comments: make 10% of your mix with some type of oil that will float to the top and seal the acetone that's in the mix from air exposure. It's an old food canning method. I made hominy, poured it in Mason jars with it's boiled water, then added vegetable oil to top off the Mason jar with about 1 inch of the oil. That hominy has been sitting for 5 years undisturbed and it's not one bit spoiled. SO, putting 10% oil in your mix might just help keep the acetone from evaporating from whatever container is used. Shake before using, then let nature separate out the mix's components with the oil floating on top.
hi Chris, try to use diesel fuel instead oft Acetone. it works better and it wont catch fire in case you heat the stuck nut. Also if you heat it just a little bit it will penetrate way better than with acetone
there is a chemical reaction with acetone and iron that makes ferric carbide, converting rust to a brittle substance that breaks under load (loosening).
l worked at the company that made WD40 It was just White Spirit and Industrial Lanolin ,,,lf you go to a pharmacist or chemist as we call them and buy some Lanolin cream then call at a DIY store for some white spirit or ( mineral spirits (US),[also known as mineral turpentine, turpentine substitute, petroleum spirits, solvent naphtha (petroleum), varsol, Stoddard solvent,[4][5] or, generically, "paint thinner", is a petroleum-derived clear, transparent liquid used as a common organic solvent in painting and decorating. l suggest mixing 10 % of lanolin and 90% of spirit in a metal or glass container ,,,,,shake it well until it is well dissolved and fill up you oiling can like in the video............. at the company we mixed 500 uk gallons of spirit with 45 uk gallons of industrial lanolin ,,,,,,mixed it till it was well blended and then packed it into aerosols or 1/2 uk pint tins hope this is of use
Cool, they sell 1 gal jugs of wd-40 at places like home depot. It's less than $20 as I recall. I'm not sure I could make it myself much cheaper than that price. Plus there's the effort of mixing and finding ingredients. I still buy aerosol cans, they are expensive but occasionally you find deals or just buy them from wal-mart. The trick with the cans is to really understand when and where to use WD-40 and use it sparingly. The spray action is really nice and often needed. I think I'll try reusing the the non aerosol spray types they sell, I don't like tossing aerosols and discharging the harmful gas. As an aside, there was a guy that came up with a really nice homemade seafoam recipe, it consists of 3 easy to find ingredients and really did seem very similar to store bought seafoam. But I don't think I would try it in my brand new car. Just google homemade seafoam if you're interested.
Thats a great video, nice job. Acetone evaporates really fast.... 50/50 naptha and ATF will evaporate slower. Sometimes I blast the parts every few hours, and try again tomorrow. The Naptha/ATF mix is better for those "long term" attempts.... Slightly off topic, but a great homemade cutting lube, like for drilling holes in metal, is 50/50 WD40 with Mobil One 5w30. our drill bits will stay nice & cool and stay sharp, and the chips will keep moving out of the hole. I like your videos! Nice job!
The recent Project Farm video penetrating oil test solves the question of which penetrating oil is best at loosening rusty bolts, and, maybe surprisingly, Liquid Wrench was the clear winner, with the acetone/automatic transmission fluid mixture coming in second. Kroil cost 3 times more and compared poorly.
Hey Chris, I've been using this home made penetrating oil for years and it works great. But there's something you didn't mention that you may not realize. I put mine in a small glass bottle with an eye dropper. Because of this I realized that the acetone will separate from the ATF and rise to the top. So before you use it, it needs to be shaken up. Without shaking it up, you'll just get pure ATF in the pump.
If I don't care about the area I put it on, brake fluid works well due to its caustic nature. It dissolves rust and other crap off of threads decently. I personally reserve this for an emergency situation, when I'm away from my shop, or have no other options. When I have to I can usually find a fast food straw somewhere in my car and dip a little brake fluid out of the reservoir.
The machinist magazine article was actually reasonably scientific (part of my job was assessing this in professional publications). They used a standard corrosion technique to make a matched set of fasteners. I was amazed at the effectiveness of the acetone/ATF mixture and now use it routinely. A key element was time. A 24 hr. soak period was best (or probably even longer). So If you can anticipate it; start early! BTW: Acetone attacks many plastics but not PP (polypropylene) (code 5) or Nalgene. You can get acetone safe containers on Amazon if you really have to have 'em.
Totally agree with the time factor. When you get pissed off with the seized bolts, apply the penetrating oil, walk away and if time permits, leave it til tomorrow. If you even see one that might give you grief when you start a disassembly, apply the penetrating oil and spend your time undoing everything else. Give the stuff time to work.
Thanks Chris, If you add 1/3 or less light weight motor oil to your mix it will also lubricate. Also you can use an old discarded plastic spray bottle for a container. thanks for all your helpful info. You have saved me $1000s .
If the acetone is separating try using less acetone. Acetone will have a limited miscibility with the oil. Acetone has a much higher polarity than the motor oil. Try this, take some oil and add a little bit of acetone and mix into solution. Repeat acetone additions until they separate and you will find the saturation point.
Hi Chris , I have been a machinist for more than 30 years and never heard of this but I am going to give it a try. In the past I did crack repair on cylinder heads with a taper tap in cast iron and broke my share I got one stuck and tried break clean and it works great so I mix that with oil for tapping it works good but I will try your stuff out for tapping and bolt removal. I really like your vids and I am a subscriber keep up the good work.
This was a while ago but if I remember correctly those were the only cups I had laying around and I managed to work fast enough. Would definitely recommend anything else though lol
I made this back in 2010 and used it on a pitman arm nut. I broke two breaker bars and wrapped the handle of my 3/4in drive ratchet around the head. After soaking it in acetone and transmission fluid for about two days it finally broke loose with still around 175ft/lbs. I had used a gallon of pb blaster over a 3 day period and still couldn't get it to break free.
My dad used this to replace our front wheel bearing in our Infiniti fx35 cus it seized the truck was like 10 years old and the stock bearing so yeah we also used your bearing video it helped a lot thank you Chris keep up the work your 👏 awesome
The problem with this is that the acetone will break down and separate from the ATF within a few days. I would use mineral spirits or kerosene for those reasons.
I use ATF and mineral spirits for bike chain lube. There's no way I would pay $7 for a small bottle! Guess I'll use it for car nuts, too. I have it in a small Mason jar and use a kids' watercolor paintbrush to dab or drip it on.
I am confident that your recipe is not only safer but may work better. I used this video as an inspiration to create some but I had none of the 2 ingredients you used. So I did 4 parts power steering fluid, and 2 parts mineral spirits then it felt kinda watered down so I picked up the greased lighting, on the way back to the trailer, put about a 2/3 cup and I mean it’s slicker than owl snot. I may not have a tongue on my trailer in the morning but at least it’s not stuck on my truck!!! Thanks for your time and info on the video!
the very best thing about this is I alway have transmission fluid and acetone or some type of paint thinner in the garage so if I run across a hard to break nut and find I am out of PB Blaster I don't need to make a trip to the store. one thing I didn't know was that this mix worked better. I always used it as a better than nothing substitute I guess now this will be my main go to for rusty nuts & bolts. Thanks Chris
Chris, next time use Type F ATF instead of the Mercon. Type F is lower viscosity and has zero friction modifiers so it attaches to metal stronger than modern ATFs. The reason it makes a lousy transmission fluid today makes it a great penetrative agent.
Is Type F ATF also fully synthetic? I'm looking at the motomaster brand, and its actually cheaper than modern brands. But it does not say if it is fully synthetic.
Been using this for years. I keep a few quarts of ATF from changing the fluid on my truck and use that. Doesn't seem to make a difference vs new ATF. I also use ATF for a gun cleaning solution. For best results, wire brush those rusty nuts and bolts if possible before using the penetrating oil
gonna drown the living sh** out of my O2 sensor tomorrow. I mixed ATF (I think Type A) and Kerosene/paint thinner. Either I aint using enough (probably) or it's on there for life
I have found that the best ingredient is time. The longer you can wait the better. If I know far enough in advance, I will apply the fluid a day or two ahead of time. Time makes a big difference.
Well iJust wanted to offer some input brake fluid will eat up rust remove paint from plastic parts its a good solvent and vinegar will eat up rust and pvblaster works real well for rusted bolts and nuts good video on homebrew penetrating oil
Speculating, but probably no one sells this because acetone fumes are toxic, and it also dissolves and lifts paint, so not very consumer friendly in non-automotive applications. Also, some places ban this kind of uses of VOCs. I note that by the time you buy the. ATF and acetone, this isn't inexpensive, but worth it if it works. For amateur mechanics, there's no real reason to mix up more than you need for a particular job.
Ed's Red MIx = 1/3 Acetone, 1/3 ATF, 1/3 Kerosene Application of heat can be useful Another good product is CRC Freeze-Off PATIENTS - allow time for product to work - it may take days if you don't want to have breakage. Works like magic
I wonder if replacing the acetone with rubbing alcohol would make a nice penetrating fluid for bolts that are either surrounded by plastic or for tough plastic bolts themselves.
RoboTekno Yea, I dont know. The acetone is really what eats away the rust and I know alcohol doesnt really have that effect. Even if it makes it less potent, it might be worth it for those bolts near rubber!
Rubbing alcohol is 15 percent isopropyl alcohol in water, so it won't mix well with the oil that you are using. Using a solvent such as varsol, which has a much higher boiling point than acetone, will be less apt to soften plastic parts. Both acetone and alcohol will dry out rubber seals by leeching the oil out of them, making them brittle. Varsol won't harm rubber parts with limited exposure. I'd be more inclined to try this with a spray bottle, varsol and used motor oil, since that's free.
ChrisFix Take a rusty bolt and drop it in a metal cup full of acetone, and cover it for the night. Then next day, you will find the bolt in the cup of acetone with probably very little colour change. Iron Oxide(rust) is not soluble in acetone. The reason this works so well is that the acetone, being such a light solvent, has really good creeping power and since it is mixed with oil, a lubricant, the oil goes for the ride. The solvent dries up and leaves the oil behind, which drops the level of friction between the treads of the bolt and nut, which were increased from the rust.
I use diesel or Kerosene mixed with ATF and Marvels Mystery Oil. Most penetrating oil is similar to the Marvels formulation (naphtha oil) and the wicking action of ATF is amazing. Never considered Acetone as an ingredient.
melaniew77msn As much as I love the MMO it is not as cost effective as ATF and I mentioned it above acetone is carcinogenic. Why try to survive cancer when you can avoid it.
ScorpionRegent Now you've given me another thing to worry about because I have already stopped eating, drinking, breathing, and going out during daylight hours out of irrational fear. Please cite your scientific source for the carcinogenicity of acetone. I'm curious. BTW, rumor, "widely believed," and myth don't count.
+melaniew77msn darn it, I was going to say that!!!!!! ATF has sealing detergents and marvels is more of a solvent and cleaner, so I'd be willing to bet that the marvels mix works better.
The penetration is not dependent on viscosity, it is dependent on the surface tension of the fluid, because penetration is basically capillary action. Although there seems to be a correlation (which you take for granted), there are plenty of examples that do not follow it. That is not to say I did not appreciate the video, just a friendly tip :)
Excellent video! Keep up the good work, Chris. Thanks for including the magazine's semi-scientific results (4:10), i.e. the TORQUE reduction of various commercial oils (WD-40 is basicly fish oil, and the newish "WD-40 PENETRATING" was absent) I was amazed that with the 50-50 ATF-Acetone mix, dry torque was almost 500% higher to turn! This should be more widely broadcast- but too many forget that acetone is super volatile, poisonous and very flammable. Un gros merci de Montréal, Quebec. A big thumbs up!
+Lofts Sympatico Acetone is not really poisonous. Yes it will kill you in large quantities, just like alcohol for example, but getting it on your skin or drinking it in small amounts isn't dangerous.
Yeah it only melts SOME plastics and not others. All styrenes readily dissolve in Acetone, as does PVC. Which is specifically so unfortunate because they are the cheapest plastics, and a lot of things have components made out of these. HDPE and PP are immune, and that's what they actually make nail polish remover bottles from. Among rubbers, there are some that will last a while, some which will dissolve instantly, but Polyisobutene, as well as natural latex rubber and Polyisoprene should be fairly resilient. These oilers being often far east imports and specific mechanical properties of rubber and its batch consistency being unimportant, chances are, it's natural rubber. White Spirits have been mentioned in the video as a possible alternative to Acetone, but it's more difficult to find a rubber that will withstand them long-term, because they will usually contain MEK.
I sort of know the answer to this one... I made some up of this solution up and kept it in a syringe. It worked fine but after approx. 6 months the rubber seal in the syringe simply dissolved/fell apart.
Thanks for sharing the video! I found you channel a few months ago and now I'm a great fan of yours, I don't miss any of your videos! I've done a little research because I couldn't find acetone on large quantities and found out that ethanol is less dense than acetone and isopropyl alcohol is even better than ethanol because it has the smallest density so it would be even more effective and less reactive with materials like plastic. I tried it with ethanol and had great results with some bolts on my car
Am I the only one who noticed a St.Petersburg produced bottle of acetone? :) Chris, I very appreciate your videos about car maintenance and tuning and always glad to watch a new ones. It's fascinating, informative and easy to understood. Also it is great how you pay attention to subtle details. Many thanks for your work from russian subscribers! P.S. Some witty comments also makes me laugh often, so it is a double more interesting to watch your videos ;)
You have noted some people use kerosene-based mixtures. Did you measured it in comparison to acetone ones? Speaking on-topic, I had a pretty good experience using pure kerosene and its mixtures with very few motor oil and rust remover (not more than 10% of both) because pure kerosene is almost perfect penetrant. It was really long time ago, and now I will definetely use an ATF instead of regular motor oil to gain even less viscosity. Also kerosene is not so aggressive to rubber parts, for example in situation you need to loose bolts on silentblocks and it is easy to accidentally spray this potion on rubber.
WARNING; Keep Penetrating Fluid, away from your girlfriend/wife as it will quickly turn into a very, very painful situation, or label it something to do with the car!
great vid Chris! Heard about this for quite some time, gonna have to try it soon. For all those asking if the acetone just evaporates in a short time, try taking the lid of your oiler and put a piece of plastic wrap over the opening and screw the lid back on. D o this while storing it! Should last forever. I have acetone thats been in containers for 5-6 yrs now, and it hasnt evaporated! Also, lacquer thinners should do the same job as acetone, incase only one of these products are available.
We used to always make penetrating fluid with motor oil and mineral spirits. It also worked good for keeping light to medium duty drill bits and reamers cool.
As a retired mechanic, you're very good at instructing and covering a topic thoroughly. I've used the ATF Acetone mix for over 30 years, and swear by it. It is the best penetrant
+iceman22st Thanks a lot!
i used vaseline -.-
+iceman22st I agree. I was using PB Blaster for the longest time. Had a stubborn bolt so I did some research. I found the study Chris showed in his video so I made my own 50/50 ATF and Acetone mixture. Worked great, been using it ever since.
Just don't use it with your girlfriend...
Iceman22st have you ever tried oil of wintergreen?
Wish I had this 5 years ago. It took me 12 applications of WD40, 10 hours, 5 knuckle scrapes, 7 cuts, 4 bruises, and 1.5 pints of blood, sweat and tears to loosen the bolts on my EGR valve that I later found out didn't need to be replaced
+Nicholas Wright I'm working on that too now. I can't get the big bolt off the side of the EGR that comes up from the exhaust.. words of advice?
+Nicholas Wright didn't need replaced? Quit looking on the internet for answers.
BlueMacGyver I didn't look on the internet and that's my point. I went off the information given to me by a professional ASE certified automotive technician that my EGR valve needed to be replaced when it was actually only a sensor. If I had done my own research (like I do now), I would have realized this and saved a lot of time and money.
Chantless Lawson Don't really have any tips to make it easier but before you buy a new one, try cleaning it with carburetor cleaner
& cursing too?
75% Blinker Fluid and 25% Orange Juice
lmao
Is that synthetic blinker fluid and oes the oj have to be pulp free?
75% blinker fluid 24% orange juice 1% soapy wooder
yeah 5% water 50% blinker fluid 20% oj
Alex Knight Gaming works great on rusty muffler bearings
This really does work great. I recently was bleeding the brakes on a 1997 Chevy 1500, and since I'm fairly sure they were the original calipers and brake cylinders I didn't have much confidence the bleeders would come loose. I put a little of this on them, let it sit for awhile, and they opened right up.
A tip is to make sure you get your own acetone. My wife wasn't very happy that I stole her nail polish remover.
Marissa Calcione
This is not meant for battery terminals (unless they are stuck and you are trying to remove them). You can use WD40 and that works decently. You can also use silcone spray which works great or Vaseline. Just put a thin coat.
ChrisFix Why did you change the liquid wrench and atf/ace bolts around?
powerbagle what do you mean?
***** I still dont know what you are talking about. Nothing got switched around?
i guess they got switched around before the fluid got put on.
powerbagle Nothing got switched haha. I cant really get any more clear. Why would the bolts get switched?
Hey Chris. I just used your Acetone/ATF fluid mix on my 15 year old Altima's control arm body mount bolts. Worked awesome. I let it sit for a weekend and it did the job. I'm in Toronto and we heavily salt and brine our winter roads. Had my torch standing by, but wasn't needed. Thanks for all the great videos. Saved my bacon many times. Stay safe.
+Andrew Peters, I cannot reply to your comment for some reason so I hope you see this. I would get a car polish or some type of scratch remover polish and use that. Toothpaste can damage your paint if you use the wrong type. Dont use WD40 either. If you want to try something before you go out to get the polish, try car wax first.
???
More like 45% ATF, 45% acetone, 10% dissolved plastic cup :p
I was thinking the same thing when I watched it lol
Your dumb the plastic didn't mix from that cup maybe if he waited few MIn and then if put in and even if I did it wouldn't matter it's to remove rusty bolts so not to put in your motor
you’re*
It was a joke you dumb ass
10 percent was probably for comedic exaggeration, but there are definitely trace amounts of plastic in the mix.
Hey man, this homemade penetrating oil rocks! I have a wheel suspension joint that was stuck due to rust. Used lots of liquid wrench, hammering, etc. but to no avail. I made up what you said: mix acetone acetone and ATF, spent $8. It was magic!
Thank you, Chris! I love your videos. Straight to the point with no intro, no music - very much appreciated.
Project Farm Channel did an in depth review of penetrating oils and the conclusion was that Liquid Wrench was #1, DIY mix with Transmission Fluid 50:50 Acetone was #2, and Kroil came last and was the most expensive. Avoid Kroil.
Penetrating Oil is usually a mix of low viscosity (very thin) oil + solvents to degunk old oil and rust. Liquid Wrench does not have Acetone or Toluol (Toluene) which can strip paint and dissolve plastic. The DIY solution has Acetone.
When you use this DIY mix on unpainted bare metal it is fine and very effective. Do not use it on any plastic, acrylic, nylon, or painted parts as it will dissolve them. I use penetrating oil for freeing up vintage sewing machines that have seized up due to old baked on oil. I can only use this or carb cleaner on all metal parts not on plastic, or belts, or painted exterior. Viewers please be aware of this constraint.
I mixed motor oil, gas, actone, Pepsi, dish soap, baking soda, embalming fluid, water, orange juice, and ky together. I wasn't making anything just started mixing things.
Sounds like you were out of beer !
Wahhahahaha!!!
We're you drunk
LOL.. hahaha
You fool
Didn't think it was possible but this is magic on anything that's rusty. Used it on 20 year old Toyota Tacoma to remove the o2 sensor. I thought that maybe it hadn't been on right but before I sprayed the 2nd o2 sensor, I attempted to remove it and there was absolutely no way it was budging. So I sprayed it waited maybe 10 or 15 minutes and it came right off with no force what so ever. I was blown away I came in all excited telling my girl. No bs I even called my dad. I have used this mix on crescent wrenches, c clamps, I even used it on my hinges off the doors in my house. Works like nothing I've ever seen. I was completely amazed. Never ever ever will I buy e40 or anything similar.
Thanks Chris
Thank you, thank you, thank you Chris! Had a stuck spark plug that wouldn’t budge and was afraid of stripping threads on an aluminum head. Put this mixture on and let soak overnight and in the morning BAM, loosened right up!!
I'm glad it worked for you! It really gets into all the tight spaces!
@@chrisfix Thanks again and possibly saved me a lot of money! Keep making the great vids!! 🤙🏽
Saw this post by accident. One day later I am in the driveway blocking the garage under my car on jack stands with a socket and a cheater bar pulling so hard I'm afraid I'm going to break the socket or pull the car off the jack stands on top of me. Had a very small old time oil-can oiler that was all metal and the ATF from previously working on my Altima. Off to the wife's makeup cabinet for the nail polish remover, its got other chemicals in it besides Acetone. All I have, so I go for it. Mix it up. Put it on the bolt. 3 minutes later, no change, can't get it off. Go back in the house. No Auto Transmission fluid (CVT) in this car, if I can't get this fill plug off the car it gets on a car hauler to the dealer 50 miles away. Uggh. $$$$$. Fifteen minutes later I try again. While I'm trying to put the cheater bar on the socket wrench with almost no pressure the fill plug breaks loose. I take it off with my fingers! It was like magic. I couldn't believe it. I am like an excited kid telling my wife about this. I was skeptical when I saw the post, not anymore. I'll be buying a modern oiler with real rubber to keep the acetone from evaporating. Never wasting money on commercial products again. Nice save, Chris. The wife is happy her car is off the jack stands and in the garage!
bro you admitted to your wife about using her nail polish remover in the garage? all the struggles aside and this, hw r u still alive ??? 😂😂😂
@@vardaanagarwal3629 he probably isn't now
@@plaguex1 😝😝🤣🤣🤣
do that repitedly, once evaporated in about 8min after the last application, use heat from an open flame (if you have a "jet lighter" the better) and then use your braking bar
I tried this and it does work! My only problem was that I used a cheap Chinese oiler from Advance Auto. The acetone destroyed the pump and fused the paint on the threaded top of the can to the pump section. I could not separate them. I had to toss the entire oiler out. I have bought a new oiler from Amazon. It is a one pint GoldenRod oiler. It was made in the U.S.A. It has no paint on the threads and the filler cap is made of brass. It should work well and last a long time.
Thanks so much for the “knowledge sharing” Chris. I just made the ATF/Acetone solution that you demonstrated in your video and it is working like a charm. It’s plain to see (actually hear, lol) that you’re an intelligent guy with a natural ability for teaching others what you know and understand. Well done and keep up the good work!
You can use generic hydraulic fluid (from jacks, tractors etc) instead of atf. Also, atf and gasoline mixed can be used in a pinch. I've also used staight diesel fuel; its not super effective but can be better than nothing and is also good for cleaning/degresing car parts.
Made some of this stuff this weekend to remove some super rusted spark plugs and it worked like a champ...PB Blaster couldn't do anything (I ended up breaking off one plug before I finally went and bought some acetone), but this home brew really loosened everything up.
Good vid. Good channel. Subscribed.
Awesome. That's what I like to hear! Glad it worked well.

+nw8000 Be careful removing plugs in a warm engine if it has aluminum head. Can pull the threads out. Engine should be cold with aluminum heads.
+john smith +nw8000 that's important enough that I'll repeat it, you should never pull plugs out of an engine warm, especially one with aluminum heads. You can usually get away with it with a iron headed engine but you'll mess up an aluminum headed engine. Even if you don't pull the threads out the first time you'll weaken them and they will come out later. This is why there are so many ways out there to put new threads in the spark plug hole of an aluminum headed engine.

Great video. Been doing this for years, works great. I repair office machinery (copiers, scanners, etc) Copier fusers (heaters) run 350 degrees while copying so the bearings often freeze to the shaft if the previous tech didn't place high temp grease on the shaft prior. Of couse we couldn't use this mixture, but we often use a 50/50 of regent isopropyl and light machine oil. I've used this mixture on some pretty rusted nuts in automotive also. Didn't work as well as the atf/acetone on brake rotor, but it does work well on smaller nuts and doesn't eat plastic. Overall, you can put it in a precision oiler and just dab it on where you need it. Even if you really don't "need" to use it, the job will go faster with less stress on the hardware during the disassemble/reassemble process. Use it constantly.
Thankyou. Your info is golden. Many channels support this formula. Its obviously a winner. The acetone only eats certain plastics. Clearly. I store acetone in used plastic coca cola bottles
omg! Im sure you get this alot but you're a genius! putting lift kit on a jeep cherokee and at my wits end, but as soon as I tried this it was off in a flash! You saved me a hundred bucks in bolts and hours in drilling! thank you so much. sincerely ChrisBreaks... in Oklahoma.
This is great. One other tip. Keep this stuff the hell away from rubber too (brake lines, boots, bushings, tires, etc.). ATF damages rubber. Acetone probably evaporates too quickly to matter. Wipe it off any rubber it gets on at least.
Every time I watch one of your videos, I learn something new! Keep up the good work.

Same here! Your channel rocks. I've watched all Scotty Kilmers vids along with some from Engineering Explained, ETCG, Robinson Auto and Real Fixes Real Fast and yours have a different style which I love. You're a great teacher. Thank you for sharing your knowledge!!!
Thank you for this video. I recently was at menards and stopped in the lube aisle to grab a can of penetrating oil. I saw a 7 oz can of kroil for 26 bucks. I thought to myself you cant be serious. That led me down the path to make my own. Best part was i had both ingredients in my shop already. So I just ordered a metal spray can and now I have a 32 oz can of the stuff and still enough ingredients to make another batch. The days of overpriced penetrating oil are over.
i am a single mother and i do all my own mechanic work, i love all of your videos chris! thank-you so much for them, they have helped me a great deal!
OMG! this has made my Auto DYI life so much easier. Thanks for sharing Chris!
I am here because I saw an ad for a new penetrating oil called "Superzilla". I went to their website and they want $12 for an 8 ounce bottle. What the hell? I will definitely be trying this recipe. Thumbs up and thank you ChrisFix.
A theory after reading comments: make 10% of your mix with some type of oil that will float to the top and seal the acetone that's in the mix from air exposure. It's an old food canning method. I made hominy, poured it in Mason jars with it's boiled water, then added vegetable oil to top off the Mason jar with about 1 inch of the oil. That hominy has been sitting for 5 years undisturbed and it's not one bit spoiled. SO, putting 10% oil in your mix might just help keep the acetone from evaporating from whatever container is used. Shake before using, then let nature separate out the mix's components with the oil floating on top.
Great idea. Just remember NOT to use carcinogenic "vegetable" (read industrial seed oils) in your food! Use fruit oils - olive, avocado, palm.
I just successfully loosen my washing machine faucet with your idea to use transmission oil. Great idea! Thanks Chris
hi Chris, try to use diesel fuel instead oft Acetone. it works better and it wont catch fire in case you heat the stuck nut. Also if you heat it just a little bit it will penetrate way better than with acetone
there is a chemical reaction with acetone and iron that makes ferric carbide, converting rust to a brittle substance that breaks under load (loosening).
Wrong.
Both would work and a high powered impact wrench is all you need.
Would this be safe to use for removing glow plugs? Soaking over the course of a few days.
I'm really starting to like your videos man. Keep up the good work!
AnythingLoud Thanks man! Will do!
l worked at the company that made WD40
It was just White Spirit and Industrial Lanolin ,,,lf you go to a pharmacist or chemist as we call them and buy some Lanolin cream
then call at a DIY store for some white spirit or ( mineral spirits (US),[also known as mineral turpentine, turpentine substitute, petroleum spirits, solvent naphtha (petroleum), varsol, Stoddard solvent,[4][5] or, generically, "paint thinner", is a petroleum-derived clear, transparent liquid used as a common organic solvent in painting and decorating.
l suggest mixing 10 % of lanolin and 90% of spirit in a metal or glass container ,,,,,shake it well until it is well dissolved and fill up you oiling can like in the video.............
at the company we mixed 500 uk gallons of spirit with 45 uk gallons of industrial lanolin ,,,,,,mixed it till it was well blended and then packed it into aerosols or 1/2 uk pint tins
hope this is of use
john catterall Thanks for sharing John! That is pretty neat!
I thought it contained fish oil also?
cheers man most helpful shit I've read in a while
Cool, they sell 1 gal jugs of wd-40 at places like home depot. It's less than $20 as I recall. I'm not sure I could make it myself much cheaper than that price. Plus there's the effort of mixing and finding ingredients. I still buy aerosol cans, they are expensive but occasionally you find deals or just buy them from wal-mart. The trick with the cans is to really understand when and where to use WD-40 and use it sparingly. The spray action is really nice and often needed. I think I'll try reusing the the non aerosol spray types they sell, I don't like tossing aerosols and discharging the harmful gas.
As an aside, there was a guy that came up with a really nice homemade seafoam recipe, it consists of 3 easy to find ingredients and really did seem very similar to store bought seafoam. But I don't think I would try it in my brand new car. Just google homemade seafoam if you're interested.
@@aussieguy1012 Rust-Oleum brand paint had fish oil
Thats a great video, nice job. Acetone evaporates really fast.... 50/50 naptha and ATF will evaporate slower. Sometimes I blast the parts every few hours, and try again tomorrow. The Naptha/ATF mix is better for those "long term" attempts.... Slightly off topic, but a great homemade cutting lube, like for drilling holes in metal, is 50/50 WD40 with Mobil One 5w30. our drill bits will stay nice & cool and stay sharp, and the chips will keep moving out of the hole. I like your videos! Nice job!
Patrick Morrissey Thanks for the tips Patrick!
I made some of this to use when I replaced a couple wheel hub assemblies and HOLY MOLY. This stuff is no joke. It worked UNBELIEVABLY well!
I mix Blinker Fluid and wheel-barrow Greese
The recent Project Farm video penetrating oil test solves the question of which penetrating oil is best at loosening rusty bolts, and, maybe surprisingly, Liquid Wrench was the clear winner, with the acetone/automatic transmission fluid mixture coming in second. Kroil cost 3 times more and compared poorly.
Hey Chris, I've been using this home made penetrating oil for years and it works great. But there's something you didn't mention that you may not realize. I put mine in a small glass bottle with an eye dropper. Because of this I realized that the acetone will separate from the ATF and rise to the top. So before you use it, it needs to be shaken up. Without shaking it up, you'll just get pure ATF in the pump.
+Jojo Diver Thanks Jojo! I appreciate the tip!
Yeah! it's like making salad dressing using vinegar and oil...you have to shake them up first because they don't stay mixed for very long!
If I don't care about the area I put it on, brake fluid works well due to its caustic nature. It dissolves rust and other crap off of threads decently. I personally reserve this for an emergency situation, when I'm away from my shop, or have no other options. When I have to I can usually find a fast food straw somewhere in my car and dip a little brake fluid out of the reservoir.
The machinist magazine article was actually reasonably scientific (part of my job was assessing this in professional publications). They used a standard corrosion technique to make a matched set of fasteners. I was amazed at the effectiveness of the acetone/ATF mixture and now use it routinely. A key element was time. A 24 hr. soak period was best (or probably even longer). So If you can anticipate it; start early!
BTW: Acetone attacks many plastics but not PP (polypropylene) (code 5) or Nalgene. You can get acetone safe containers on Amazon if you really have to have 'em.
Totally agree with the time factor. When you get pissed off with the seized bolts, apply the penetrating oil, walk away and if time permits, leave it til tomorrow. If you even see one that might give you grief when you start a disassembly, apply the penetrating oil and spend your time undoing everything else. Give the stuff time to work.
Thanks for the tips!
Thanks Chris,
If you add 1/3 or less light weight motor oil to your mix it will also lubricate. Also you can use an old discarded plastic spray bottle for a container.
thanks for all your helpful info. You have saved me $1000s .

This is so useful! It's crazy that you can make a better product at home, cheaper. Thanks man
90% Soapy Wooder, 10% "HOLY SMOKES!!" - best mixture
I made this same exact mix awhile back, and it for sure works better than every kind of store bought pen oil
If the acetone is separating try using less acetone. Acetone will have a limited miscibility with the oil. Acetone has a much higher polarity than the motor oil. Try this, take some oil and add a little bit of acetone and mix into solution. Repeat acetone additions until they separate and you will find the saturation point.

Hi Chris , I have been a machinist for more than 30 years and never heard of this but I am going to give it a try. In the past I did crack repair on cylinder heads with a taper tap in cast iron and broke my share I got one stuck and tried break clean and it works great so I mix that with oil for tapping it works good but I will try your stuff out for tapping and bolt removal.

Good video. Curious why you used a plastic cup? Certainly you had another vessel in your home/shop?
This was a while ago but if I remember correctly those were the only cups I had laying around and I managed to work fast enough. Would definitely recommend anything else though lol
I made this back in 2010 and used it on a pitman arm nut. I broke two breaker bars and wrapped the handle of my 3/4in drive ratchet around the head. After soaking it in acetone and transmission fluid for about two days it finally broke loose with still around 175ft/lbs. I had used a gallon of pb blaster over a 3 day period and still couldn't get it to break free.
Sean Twiggs CRAZY! Yea, this stuff is great!
It is great for almost anything
My dad used this to replace our front wheel bearing in our Infiniti fx35 cus it seized the truck was like 10 years old and the stock bearing so yeah we also used your bearing video it helped a lot thank you Chris keep up the work your 👏 awesome
The problem with this is that the acetone will break down and separate from the ATF within a few days. I would use mineral spirits or kerosene for those reasons.
Avery Alexander Well he did state that in the video and said to shake every time it is used
I use ATF and mineral spirits for bike chain lube. There's no way I would pay $7 for a small bottle! Guess I'll use it for car nuts, too. I have it in a small Mason jar and use a kids' watercolor paintbrush to dab or drip it on.
I am confident that your recipe is not only safer but may work better. I used this video as an inspiration to create some but I had none of the 2 ingredients you used. So I did 4 parts power steering fluid, and 2 parts mineral spirits then it felt kinda watered down so I picked up the greased lighting, on the way back to the trailer, put about a 2/3 cup and I mean it’s slicker than owl snot. I may not have a tongue on my trailer in the morning but at least it’s not stuck on my truck!!! Thanks for your time and info on the video!
I use 50% paint thinner and 50% children's tears. Works well.
That's just dumb. I just go cut some onions.
You forgot the 2% of crushed dreams :P

When I was a truck mechanic, we always used atf mixed with diesel fuel. It worked, but I think your mixture works better.
That's awesome I will be using this technique from now on. Thanks for the big tip.
Ruben theIowan Thanks man and you are welcome! Glad you learned something new!
Wish I seen this before I stripped two rusted water pump bolts using wd40😩. Thankyou Chris for all to ur help!its much appreciated!
Amazing 10 minute fix. Thanks so much. Spray it on wait 10 minutes, back to work.
Exactly!
the very best thing about this is I alway have transmission fluid and acetone or some type of paint thinner in the garage so if I run across a hard to break nut and find I am out of PB Blaster I don't need to make a trip to the store. one thing I didn't know was that this mix worked better. I always used it as a better than nothing substitute I guess now this will be my main go to for rusty nuts & bolts. Thanks Chris
ogbobbye No problem! Yea, this stuff has saved me a few times!
Thank you for this!! I’ve got some bad bolts that needs this! I love Kroil, but it’s expensive. Gonna do this for sure!
Works fantastic! Broke my wheel bearing lose when PB blaster could not. Thanks man.
Chris, next time use Type F ATF instead of the Mercon. Type F is lower viscosity and has zero friction modifiers so it attaches to metal stronger than modern ATFs. The reason it makes a lousy transmission fluid today makes it a great penetrative agent.
Thanks for the tip! I will give it a shot!
Is Type F ATF also fully synthetic? I'm looking at the motomaster brand, and its actually cheaper than modern brands. But it does not say if it is fully synthetic.
Type F regular or synthetic ?
Works good - I used same mix ratio but all I had was Cvt transmission fluid results are almost instantaneous! P.s great video thanks for sharing
god bless you dear chris ..deep thanks & all respect
Been using this for years. I keep a few quarts of ATF from changing the fluid on my truck and use that. Doesn't seem to make a difference vs new ATF. I also use ATF for a gun cleaning solution. For best results, wire brush those rusty nuts and bolts if possible before using the penetrating oil
gonna drown the living sh** out of my O2 sensor tomorrow. I mixed ATF (I think Type A) and Kerosene/paint thinner. Either I aint using enough (probably) or it's on there for life
I have found that the best ingredient is time. The longer you can wait the better. If I know far enough in advance, I will apply the fluid a day or two ahead of time. Time makes a big difference.
The acetone type matters, some acetone is thinned with water, some is 100% acetone
Where can you buy real pure acetone?
I get mine at a local Hardware, TrueValue, also got some at Carquest before they were bought out
Well iJust wanted to offer some input brake fluid will eat up rust remove paint from plastic parts its a good solvent and vinegar will eat up rust and pvblaster works real well for rusted bolts and nuts good video on homebrew penetrating oil
Really wish I had known this.
So why don't companies sell this instead?
Speculating, but probably no one sells this because acetone fumes are toxic, and it also dissolves and lifts paint, so not very consumer friendly in non-automotive applications. Also, some places ban this kind of uses of VOCs. I note that by the time you buy the. ATF and acetone, this isn't inexpensive, but worth it if it works. For amateur mechanics, there's no real reason to mix up more than you need for a particular job.
Ed's Red MIx = 1/3 Acetone, 1/3 ATF, 1/3 Kerosene
Application of heat can be useful
Another good product is CRC Freeze-Off
PATIENTS - allow time for product to work - it may take days if you don't want to have breakage.
Works like magic
I wonder if replacing the acetone with rubbing alcohol would make a nice penetrating fluid for bolts that are either surrounded by plastic or for tough plastic bolts themselves.
RoboTekno Yea, I dont know. The acetone is really what eats away the rust and I know alcohol doesnt really have that effect. Even if it makes it less potent, it might be worth it for those bolts near rubber!
Rubbing alcohol is 15 percent isopropyl alcohol in water, so it won't mix well with the oil that you are using. Using a solvent such as varsol, which has a much higher boiling point than acetone, will be less apt to soften plastic parts. Both acetone and alcohol will dry out rubber seals by leeching the oil out of them, making them brittle. Varsol won't harm rubber parts with limited exposure. I'd be more inclined to try this with a spray bottle, varsol and used motor oil, since that's free.
ChrisFix Take a rusty bolt and drop it in a metal cup full of acetone, and cover it for the night. Then next day, you will find the bolt in the cup of acetone with probably very little colour change. Iron Oxide(rust) is not soluble in acetone. The reason this works so well is that the acetone, being such a light solvent, has really good creeping power and since it is mixed with oil, a lubricant, the oil goes for the ride. The solvent dries up and leaves the oil behind, which drops the level of friction between the treads of the bolt and nut, which were increased from the rust.
Homer Simpson Thanks for the info! It's amazing how well it works!
I have used ATF alcohol mixture it does work well.Acetone may work better.The alcohol does evaporate fast so it really doesn't store well.

I use diesel or Kerosene mixed with ATF and Marvels Mystery Oil. Most penetrating oil is similar to the Marvels formulation (naphtha oil) and the wicking action of ATF is amazing. Never considered Acetone as an ingredient.
Acetone and marvel mystery oil mixed 50/50 works wonders also!
melaniew77msn As much as I love the MMO it is not as cost effective as ATF and I mentioned it above acetone is carcinogenic. Why try to survive cancer when you can avoid it.

You are doing science! you are performing an experiment and observing results.
The penetration is not dependent on viscosity, it is dependent on the surface tension of the fluid, because penetration is basically capillary action. Although there seems to be a correlation (which you take for granted), there are plenty of examples that do not follow it. That is not to say I did not appreciate the video, just a friendly tip :)

ARE YOU CRAZY ACETONE IS P.O.I.S.O.N.O.U.S!!!!!!!!!!! EVEN A T-R-A-C-E AMOUNT!!!!!!!!
nope.. thats why its used in nail polish remover
Was struggling with a rusted egr bolt for 1 week and came across that..
It's like that bolt was never tightened. Thanks a lot!!!!!
if it melts plastic doesn't it melt the rubber gaskets on the oiler? just curious
No
+julio Angel rubber aint plastic :) atleast not propper rubber :)
Yeah it only melts SOME plastics and not others.
All styrenes readily dissolve in Acetone, as does PVC. Which is specifically so unfortunate because they are the cheapest plastics, and a lot of things have components made out of these. HDPE and PP are immune, and that's what they actually make nail polish remover bottles from.
Among rubbers, there are some that will last a while, some which will dissolve instantly, but Polyisobutene, as well as natural latex rubber and Polyisoprene should be fairly resilient. These oilers being often far east imports and specific mechanical properties of rubber and its batch consistency being unimportant, chances are, it's natural rubber.
White Spirits have been mentioned in the video as a possible alternative to Acetone, but it's more difficult to find a rubber that will withstand them long-term, because they will usually contain MEK.
Siana Gearz. you know your polymers :)
I sort of know the answer to this one... I made some up of this solution up and kept it in a syringe. It worked fine but after approx. 6 months the rubber seal in the syringe simply dissolved/fell apart.
Thanks for sharing the video! I found you channel a few months ago and now I'm a great fan of yours, I don't miss any of your videos! I've done a little research because I couldn't find acetone on large quantities and found out that ethanol is less dense than acetone and isopropyl alcohol is even better than ethanol because it has the smallest density so it would be even more effective and less reactive with materials like plastic. I tried it with ethanol and had great results with some bolts on my car
its easy to penetrate down, you shold test and see if it penetrates sideways.

P.S. Some witty comments also makes me laugh often, so it is a double more interesting to watch your videos ;)
You have noted some people use kerosene-based mixtures. Did you measured it in comparison to acetone ones?
Speaking on-topic, I had a pretty good experience using pure kerosene and its mixtures with very few motor oil and rust remover (not more than 10% of both) because pure kerosene is almost perfect penetrant. It was really long time ago, and now I will definetely use an ATF instead of regular motor oil to gain even less viscosity.
Also kerosene is not so aggressive to rubber parts, for example in situation you need to loose bolts on silentblocks and it is easy to accidentally spray this potion on rubber.
To much money I spent on wd40..
WD40 - not good for anything. Surely everyone knows that by now.

great vid Chris! Heard about this for quite some time, gonna have to try it soon.
For all those asking if the acetone just evaporates in a short time, try taking the lid of your oiler and put a piece of plastic wrap over the opening and screw the lid back on. D o this while storing it! Should last forever. I have acetone thats been in containers for 5-6 yrs now, and it hasnt evaporated!
Also, lacquer thinners should do the same job as acetone, incase only one of these products are available.
+Giuseppe Agostinelli Awesome! Thanks for the tips Giuseppe!
Hi Chris, I want to help you with the subtitles in Dutch but I don't know how to do it
Google.

We used to always make penetrating fluid with motor oil and mineral spirits. It also worked good for keeping light to medium duty drill bits and reamers cool.
