You want rust on your chain. Rust is nature's way of automatically reducing further oxidation. If you have a bike chain that oxidizes easily, the answer is to put it in the recycle bin and buy a good stainless steel one or aluminum.
@@earthenscienceNo, you do not want rust on your chain or any other bike part, at all. And rust doesn't stop when the top layer is rusted, it keeps on eating away at iron-based metals until there's literally no metal left. Best way to prevent rust on bike parts is to not store them outside and dry them thoroughly if they get wet, and keep all moving parts lubricated. A clean and well-lubed chain won't get rusty. And who ever heard of aluminum bike chains?
@@kovie9162 Rust (iron oxide) is inert, it doesn't do anything other than act as a protective coating. It is a byproduct of oxidation. Ideally you want to convert rust into something else, because rust is flaky so it is a poor protective coating. It is shown that a coating of rust significantly reduces the rate of oxidation. That being said, rust is bumpy, so it will add more friction to your bike chain. If your bike chain has too much rust then it is just junk, if you clean the rust the parts will just be smaller than before, causing the chain to be stretched. And also the parts will be bumpy. That is why you need titanium chains. I am not sure about aluminum chains anymore because they said that aluminum mining is unethical. But the concept of aluminum chains is to prevent rust. You could make strong chains out of aluminum 6061 t6 or 7000 series aluminums. Titanium chains don't rust like steel does and rivals the strength of steel, also it is lighterweight than steel.
@@earthenscience Perhaps that happens under certain conditions where there's very little moisture or humidity, but when subjected to moisture of any kind, either water or humidity, iron and steel WILL rust continually until all the metal is gone. That's why they call the Rust Belt the Rust Belt. Or, as the saying goes, rust never sleeps. It really doesn't. And even if this weren't the case, as you say the existing rust would severely impact efficiency. You might be thinking of oxidation in aluminum or titanium, where the initial oxidation layer often protects from further oxidation. But not iron or steel unless it's very dry. You want to ALWAYS get rid of rust as soon as you spot it, and prevent it from coming back by coating with an appropriate lubricant and keeping it out of the elements. And no one makes aluminum bike chains that I know of. It's just not strong enough at the kind of thickness you'd need with today's narrow cog drivetrains. Simply wouldn't work. And Ti is too expensive and not terribly hard, and would wear away faster than steel chains. There are Ti cogs and rings, but they too are very expensive and don't last long, mainly for rich people and top racers. Ti is an excellent frame material though. My frame is Ti. It'll never rust or corrode and treated well will outlast most cyclists.
Then, you just have to use only vinegar instead. Vinegar + baking soda undergoes a reaction, producing water, carbon dioxide (that's why You get the bubbling effect), sodium ion, and acetate ion. None of these components has a rust-removing effect; moreover, you get more water, which can contribute to more rust. The misconception regarding vinegar + baking soda arises from variations in ingredient proportions. Depending on the amounts used, after the reaction, there may be residual primary components that effectively contribute to rust removal.
I use vinegar only and it can remove any amount of rust, just give it some time. However, it changes the color of iron slightly, I suppose it is some kind of coating as a result of the reaction of the vinegar and the iron.
Baking soda and vinegar neutralise each other so it's completely useless😂 I have restored old tools with white vinegar I should try brown vinegar see if it's better lol
Vinegar and Evaporust are the two very good products that you should try next. I use vinegar for light rust, it works very well, is cheap and is weak enough not to harm the parts (as long as I don't leave them in there for weeks). Evaporust is more expensive but works great and won't harm the parts at all. It's really a miracle product.
Evaporust is quite effective and you can reuse it. Very little if any scrubbing is required. It’s also quite safe to use. I soak the chains (or any other rusty object) overnight.
The only time I had to try I used vinegar with salt as an abrasive. It worked. Then I washed it, the neutralized it in water and baking soda. I don’t know about that last part, but that’s what it said to do.
Hi Alex. Yes a bit of fun. The obvious question is did you check to see if the rust remover made more play in the chain (ie scrap anyway). The second observation is what about the bits inside the chain that you can't reach eg the inner plate under the outer plates, and of course the rollers. Even if i thought I might use it again after the rust eater stuff, I would certainly want a thorough cleaning to totally get ride of the acidic chemical. I have seen it suggested that molasses and water work but........ So bottom line, get a new chain and don't mess about.
You want an acid to reduce the rust. Coke (phosphoric acid) or white vinegar (acetic acid) should work. However you should degrease the chain before else the acid will not have a chance of getting to the surface, as the grease/oil is still doing it's job of protecting your chain.
That pink rust remover goes by a lot of names one is Naval Jelly its used to treat metal surfaces on Naval equipment. As a retried mechanic I sometimes used coke to remove the built up piles of white corrosion on batteries, never drink the stuff.
Try vinegar and salt. I used them to de-rust my Park Tool tools. Until today, 3 years later, the cutter is still rust free. The vinegar turned the surface of the steel grey and I think that is what protects the metal.
You need a solvent for that baking soda! Also, the phosphoric acid in coke is probably more dilute than in the rust remover, so you'd probably want to give the Coke a longer soak time to make it a fair test.
I mean if they follow the instructions then it would be more scientific and factually right but they or at least this presenter doesn't follow that it seems on any video of comparisons. Mabey a look at project farm and his setup for comparison testing would give them the basics of doing a test right.
Yes that is right. Cola is cheapest and it works almost like rust remover if you can (have a time) to let sit it there for 24 hrs. After it most of the rust is removed just by clean cloth. But scrubbing is recommended too :). (btw coca cola can greately wash blood from the road tarmac too).
the thing about the pink rust remover, it actually converts to the rust back into clean unoxidized metal as opposed to the coke or vinegar which is removing the oxidized metal. as mentioned by others the baking soda is used to neutralize acids after you're done using them, otherwise they just keep eating away at the chain
The pink stuff, known as Naval Jelly here in the US, uses phosphoric acid to remove the rust. But it doesn't convert rust back to metal. It removes the rust so long as it's wet, and when it dries it then converts the remaining rust to iron phosphate, which is whitish. It's a good base layer prior to painting on things like car frames and suspension parts as it prevents future rust, but on bike parts it's just ugly and will impact efficiency on moving parts like chains. It's ok to use phosphoric acid-based rust removers on bike parts, just don't let the parts dry out and rinse them off thoroughly and brush the parts to make sure you get all the acid out, and then treat with baking soda and water to neutralize any lingering acid so it doesn't eat away at the metal. Better yet though would be vinegar, and even better is Evaporust, which is the only thing I'd ever use on bike parts that are still salvageable as it doesn't harm metal or leave any residue.
Evaporust is highly recommended and leaves a temporary barrier after use. A cheap and really effective household product is black molasses diluted 1:10 with water. Soak components overnight, rinse and immediately dry and protect with oil, grease or paint. The solution can be reused and is cheap and the effects are amazing. Similar to Evaporust, it's a chelating agent if you want to know the chemistry.
Try Evaporust, hands down the best rust remover that doesn’t remove material like acids will. Also very safe, no nasty chemicals. Also never wire brush steel or aluminum parts with a brass bristles, the brass will imbed into the steel or aluminum and cause differential metal corrosion.
It's the phosphoric acid in cola that removes rust, just at much lower concentrations because people drink it so it's not very effective. The rust remover has a much stronger concentration of phosphoric acid but you need to rinse it off right away and then neutralize it with water and baking soda afterwards or you'll be left with ugly white spots that could cause drivetrain issues. I wouldn't use it on bike parts myself although I have used it on car parts. And the baking soda didn't work because you needed to add some water first. Better would be either vinegar, which won't leave any residue although it too should be rinsed off with water and not used for too long or it'll eat away at the metal, or better yet something called Evaporust, which is more effective and doesn't harm metal, and make sure to rinse it off too. It can actually be reused many times so don't throw it out when you're done. And whatever you use, dry the chain off after rinsing to prevent flash rust from forming. You then want to clean the chain and then lube it right away. Also, I'm guessing that the effectiveness of acidic rust removers in liquid, not gel form, would be enhanced by using them in ultrasonic cleaners, especially something like a chain where you really want to get inside the rollers and between the pins and jackets. Evaporust would probably be even more effective this way. But seriously, if a chain or other bike part is rusty enough to need such treatment, it's probably no longer usable even if you remove all the rust. I'd just replace it. Steel frames of course are different, and is they're still structurally sound then can be derusted and salvaged. Just treat and paint them right away. Anyone who wants more detail on rust removal methods is best advised to search for rust removal tips for cars. Tons of advice there and most of it is good.
Use the coke , Then put it back on a bike with a good spray of WD 40 then ride it around a bit then Wipe it off , The chainring and cogs friction should help cleaning the inner bushes and plates making it half decent again.
7:32 min. long video to find out that product which is manufactured for some specific purpose beats products which are for entirely different kind of usage. What next? Some "hacks" about lubricating chains? I suggest to compare water, coca-cola, DOT 4 fluid and some kind oil. Which will be the best? Ummm, lets find out! :-)
50/50 mix of water and vinegar. Left overnight hit it with a brush and rinse it very well. It'll look brand new. Must lubricate right away or it will flash rust.
The bicarbonate isn’t abrasive without agitation 😂 You might as well stick it in a bag with some sandpaper. Also, you need a acid with it to cause a chemical reaction that might remove the rust
It depends on the extent of the internal rusting. Surface rust on the plates is of little consequence. Rust in the bushings is the problem and a wire brush doesn't help with that. Even if you manage to remove the internal rust chemically, it represents metal that is now missing from the bearing interface. For a chain that has some mild external rust and is not stiff, work in some oil, wipe down, try a short ride and then measure the chain. If the "stretch" is within limits then ride on. More serious rust will make stiff links, in which case it's likely to be out of spec even if you get things loosened up again.
Ha, ha ... your faithful viewers wouldn't ever let a chain get so rusty! The last such chain I cleaned had sat in a shed with a leaky roof for a couple years.
A little research on the part of GCN before making this video and products like CRC Evapo-Rust would have surfaced as obvious choices for testing. Rust-Oleum Krud Kutter is also an excellent rust remover and leaves the metal with a protective coating from future rusting. Anyway, to have viewers come away from this video thinking Coke is their best option for removing rust on chains is a crying shame. 😫
Coke has a ph of 2.5, and it would work if left to soak overnight. A few drops of detergent should be added to get through the grease. However, all of this is dumb. Just use Evaporust or other proper rust remover. Better yet, don't let your chain get rusty in the first place.
Hand cleaner, the one that has the grit in it that car mechanics use. My only warning is if any grit is left in the chain then it would start to become a grinding paste and ruin your derailer, cassette and cranks in no time
30% vinegar or oxalic acid are the real rust remover chemicals. I never understood why people want to use coca cola for a lot of different stuff. Why not use the stuff made for the specific application. In this case rustremover for removing rust!!
Vinegar? Vinegar soaked over 12 hrs. would have been a much better choice to clean rust off anything. Ever better would have been Vinegar and baking soda.
Did you guys change the camera recording procedure? The focus seems to be moving and the camera is not being held stable. Looks like a very badly made amature video, not the usual profession standard expected.
Who thought dry baking powder would work? One hour is not long enough for cleaning. At least a full day to start. Of course, you could not let your chain rust in the first place.
The phosphoric acid concentration in Coke is too low to work and definitely not in one hour. Dry baking soda? Really?! Why would an organic degreaser remove corrosion? Surprise, surpise the commercial rust remover worked. Pretty poor effort GCN. Organic acids like citric and acetic in everday 'stuff' will work best if you don't want to buy a rust remover.
Degrease first, then leave overnight soaking in evaporust. And rust isn't something that forms on "metal", it's something that forms on *ferrous* metals. If you're going to talk about things in technical terms, may I suggest that you actually understand those technical terms before committing those comments to video and publishing it?
The obvious question for me is - what chemicals are in Coca-Cola that makes it almost as effective as rust remover? And people still drink this stuff? 🤢
Phosphoric acid. Vinegar is basically acetic acid and lemon and other citrus fruits contain citric acid. Your stomach contains concentrated hydrochloric acid. We're eating and drinking acids all the time!
Alex GCN Pixies & Elves:- throw the chain away I ask you! Find a chain that is properly ceased! Alex Poor example of a rusty chain! Fancy saying "Gross" . You forgot NOT BAKING POWDER but CITRIC ACID or EvapOrust! And wire brush baking tray burner and motor oil used or new boil the chain and brush off! What about Aluminium Oxide? also a rust? As well as the Electrochemical rust that often builds up between two dissimilar metals eg. Aluminium Bolt and Steel fixing locking the two together.
I'd just spray it down in WD-40 and ride it 50 miles. If it's still rusty looking after that I'd just toss it lol. Chain sideplates do snap dunno why anyone would ride a rusted chain. If you're poor it makes even less sense because crashing on a bike could be fatal if you lose that paycheck.
The real hack is just using teflon coated black chains though. These never rust and they shift better than the fancy Ti Nitride coating on expensive chains too.
@@dugldoo I'd just wipe that off with a rag and relube. My chains never get rusty ever though and I would just toss them if they did so I feel you on that though.
@dugldoo this clown only rides steel fixed gears and will never wear cycling shorts. He's also made claims of power that would make him stronger than Filippo Ganna.
You should do a comparison of "proper" rust removers. Edd China recently de-rusted his entire Land Rover chassis with about 2000 litres of Evaporust, and with no scrubbing with a brush at all. Watch here - th-cam.com/video/mwxwABnAsRU/w-d-xo.html&ab_channel=EddChina
Wow, i guess there running out of things to talk about. But for heavens sakes your beating the poor horse to death..... 🥱 Dry baking soda? Really man 😊😊
Do you have any rust removal tips? ⛓
How about a product called CLR that is available in Canada? Have that in the UK? Tried?

Surely this was a video for Dr Ollie to give us a 10 minute lecture on the chemistry of oxidation....
They are still editing it down from 6 hours
I would have loved that.
I've done similar with old bolts with simple white vinegar, worked like a dream. Didn't even have to scrub either.
+1. Boiled my very rusty chain in vinegar yesterday, and holy shit did it work!
Dreamy! 🙌

You can also reuse Evaporust. I've never used it on a bike chain, but i have used and reused it many times when cleaning up old hand planes.
Evaporust is far and away the best rust removal fluid. Electrolysis is the cheapest. Forget the rest! Happy new year

In my experience, a rusted chain is a stretched chain, and must be replaced. I’d be interested if others have found this to be true.

If the chains are in such bad condition that they need separate rust removal... you can't drive them anymore 🤔
The phosphoric acid concentration in Coke is too low to work and definitely not in one hour. Dry baking soda? Really?! Why would an organic degreaser remove corrosion? Surprise, surpise the commercial rust remover worked. Pretty poor effort GCN. Organic acids like citric and acetic in everday 'stuff' will work best if you don't want to buy a rust remover.
I feel the results would have been far superior with a 24h soak
I bought a stainless steal chain, problem solved.
Was it stolen?😂
Vinegar works well.
The real answer comes at the end. It’s just time to replace with a new chain
GMBN already did this
Great job 👍🏾
However, such rusty chain, use it for something else, not worth the risk of putting it back on the bike! 🤓✌🏾
Baking Soda Gate incoming...
Wd40??
Camera is shaking too much and out of focus 😩
Wow, now there's a surprise, Silca was the winner. Who just happen to be a GCN sponsor, who'd have thought.🙄
Ya, but Silca probably didn't want to pay the shill just this once!
Degrease first, then leave overnight soaking in evaporust. And rust isn't something that forms on "metal", it's something that forms on *ferrous* metals. If you're going to talk about things in technical terms, may I suggest that you actually understand those technical terms before committing those comments to video and publishing it?
REPLACE IT. DON'T RISK SERIOUS INJURY BY RIDING A RUSTY CHAIN. A $15 chain is not worth a $15000 medical bill and much suffering.
Wd40😎
Drink the Coke and buy a new chain. I mean, who the hell wants to scrub 1m50 of bike chain link by sodding link?
Why not waiting 12 hours with the Coca Cola? That might be better than 1 hour rust remover.
The obvious question for me is - what chemicals are in Coca-Cola that makes it almost as effective as rust remover? And people still drink this stuff? 🤢
Phosphoric acid. Vinegar is basically acetic acid and lemon and other citrus fruits contain citric acid. Your stomach contains concentrated hydrochloric acid. We're eating and drinking acids all the time!
Oxalic acid is a good rust remover and its cheap.
식초가 답인가봐용
Alex GCN Pixies & Elves:- throw the chain away I ask you! Find a chain that is properly ceased!
Alex Poor example of a rusty chain! Fancy saying "Gross" . You forgot NOT BAKING POWDER but CITRIC ACID or EvapOrust!
And wire brush baking tray burner and motor oil used or new boil the chain and brush off!
What about Aluminium Oxide? also a rust? As well as the Electrochemical rust that often builds up between two dissimilar metals eg. Aluminium Bolt and Steel fixing locking the two together.
Imagine what Coca Cola does to our body
WD40 makes an amazing rust remover
Baking soda alone wont do any good, must mix it with vinegar…
I'd just spray it down in WD-40 and ride it 50 miles. If it's still rusty looking after that I'd just toss it lol. Chain sideplates do snap dunno why anyone would ride a rusted chain. If you're poor it makes even less sense because crashing on a bike could be fatal if you lose that paycheck.
The real hack is just using teflon coated black chains though. These never rust and they shift better than the fancy Ti Nitride coating on expensive chains too.
No!!! Just think of all that rust grit getting in the derailleur, on the cassette, and chain rings! Aahhh!
@@dugldoo I'd just wipe that off with a rag and relube. My chains never get rusty ever though and I would just toss them if they did so I feel you on that though.
@dugldoo this clown only rides steel fixed gears and will never wear cycling shorts. He's also made claims of power that would make him stronger than Filippo Ganna.
@@veganpotterthevegan cycling shorts are like 10 watts brah it's not worth it
The take away for me is to not drink Coke 🤔
if you have allowed the chain on your bike to go rusty - you don't deserve to own a bike
But be merciful, and help the guy who hasn't been on his bike for three years rehab it and get back on his bike.
Battery acid does it in seconds😂
Using ai generated pics in the thumbnail is a real low
Not really a hack as the title suggests 😢
Coke removes the build up crap on your car battery, and now removes rust….. and people drink this stuff!?
I’d tour chain is rusty REPLACE IT.
First
Please get rid off this shaky cameraman. It's so annoing.
Just buy a new chain, it´s not like a new one cost a furtune
You should do a comparison of "proper" rust removers. Edd China recently de-rusted his entire Land Rover chassis with about 2000 litres of Evaporust, and with no scrubbing with a brush at all. Watch here - th-cam.com/video/mwxwABnAsRU/w-d-xo.html&ab_channel=EddChina
Wow, i guess there running out of things to talk about.
But for heavens sakes your beating the poor horse to death..... 🥱 Dry baking soda? Really man 😊😊
