Once you clear the nozzle out, I think it might still be good to store the can upside down so the paint (sludge) settles in the top of the can and not the bottom where the straw opening is located.
Correct... once you clear the pickup tube and nozzle, carefully leave the can upside down and store it that way. The idea is that the pickup tube is not in contact with the contents of the can anymore therefore cannot become clogged. It'll stay that way indefinitely too. The original plastic cap from the spray can often is an excellent base for storage but if it isn't, constructing a rack using duct tape or a glue gun and cardboard from boxes is a dirt cheap way to make a rack. If you store your cans in a fire cabinet, you'll need to make a rack out of non-flammable material, if you're going to follow the usual standards. Interestingly, when I was in college in the engineering program, several students made a rack that fit into a fire safety cabinet shelf as a project. They made it from expended metal spray cans and got props for the effort to recycle. Even all those decades ago, recycling and environmental concerns were a part of what we were taught. So how did it work? They cut off the bottom & top of the cans and sliced the body lengthwise down the cylinder. The metal rectangles were folded into the parts that comprised the body of the racks which were predestined to fit into the cabinet. They used a small benchtop sheetmetal brake to do the bending. You can think of it looking a bit like an erector set without most of the holes. Anyway, while I wasn't in that group of students or even in the program in the afternoon (I was in the morning half of the program), I got to examine the blueprints, spare parts and the finished product. Every group had their project on display which could essentially make you look good... or not so much. As far as I'm concerned, they did an excellent job, produced a professional looking product and it was far stronger than anyone thought it was going to be while using almost next to nothing in additional materials. IIRC, they put a total of 200 pounds of dead weight on a rack section just to test it out and it held up like a champ. Overkill? Yes. Impressive? Also yes considering none of them had any real practical experience designing or building anything prior to that according to what we were told. Of course common sense tells me that's why they ended up going overboard with their design... practical experience is worth a lot. They just didn't have any yet! The moral of the story is that you can do a lot with common items that most people throw in the trash... and you can do it for little to no money which is usually important when you're a poor, starving college student.

Thank you Craig. That was very illustrative and very informative. One problem: when you said at the beginning that you'll help solve the problem of clogging, I thought you'd suggest ways to actually declog the can, not way to prevent the clog. I still like the video though.
To declog you've got to force air into the valve to push out the clog and then soak can in hot tap water periodically shaking thoroughly to ideally break up and dissolve the clog so that it cannot re enter the valve ..
First of all I love the history lesson and the accordion music. Being an accordion player, you definitely got my attention. but all of that aside, thank you for a most amazing and helpful instructional video. You are fantastic!
Brilliant! Thank you so much Craig for posting this informative video about a "classic" problem with spray cans that fail before being empty - you should teach, your video has very practical application and saves a lot of money (and frustrations, for me at least), Ciao, L
Thank you so much. I had my sunspray clogged for a month. And it's expensive. I've tried every safe things i know. But no one worked for me. Then, i put i upsode down and spray. It worked! Thanks again
What if I use the can for several very small jobs and repeat the process of spraying upside down until it runs clear. Won't that use up my air before the paint is gone?
Thank you! You think like me. There's really no point in attempting to know how to get something tk work without knowing why it works the way it does. I thought this would be some cool mod. I have known for years to turn it upside down and clear the can but never knew the real history and theory behind the very can I've done so much art with. This is a very cool way to go about doing did vids. First of yours I watched gets an immediate subscribe! Got to see more!
Thank you again. I tend to get carried away sometimes with details and history. I've backed off a lot on that but I'm glad you appreciate this vid. Check back for more soon.
Great show! Can I apply to a clog hairspray clan I just bought it and it seems to have no pressure so I’m wondering if that would be it? Thank you really enjoyed your educated performance have a great day.
this is the only video I could find explaining exactly how aerosols work, and it's much appreciated. could you advise on how to go about formulation mixing?
Can you make video for hair spray can. I usually get 12 or 24 in a box and at least by the time we sell off, 1or 2 cans are full but, don’t spray. Or client brings back and it doesn’t spray. But, has lot of products inside or fairly new. Please show what happens or how to restore them
Thanks for the education, luckily I had the sense to fast forward it to the important bit: as it says on click-bait: Never Deal with a Clogged Spray Can Again
I am curious how the factory filling process manages to get the paint/propellent into the can and at the same time crimping/sealing all without major leaks and paint splatter everywhere. That process alone has my head spinning!
So you do exactly what the directions say to do "after use and to prevent clogging"?!?! Who knew! Sad how many people do not read the directions. Thst being said l, great presentation sir!
I was interested in learning how to get hairspray cans to work again. I use them sparingly so lose a lot of product in the end. I guess I'll have to use spray bottles instead.
And dont throw away bu return dead half used cans to big box improvement stores. This campaign will encourage the manufacturers to provide spare nozzles with new cans.
Modern rustoleum cans can’t use the upside down spray trick as they spray from any angle now. What were they thinking? That was a feature. Is there any way to unclog them with the new cans?
Very familiar with that product. Doesn't matter what the contents. Once clogged there is no remedy that I am aware of. Sorry. Just do your best to avoid.
nice long video, pretty well informed. my problem is that new big white nozzle you showed at the end. I've shaken it s bunch and still nothing comes out. it's clogged. the can says use mineral solvent for the nozzle, but it still doesn't work. I'm bummed. so it's a third trip back to home depot to exchange it for just regular brush on glow in the dark paint for my awesome projects. btw I love Pinterest for great ideas.
+Susan Miller Yeah. I've learned to pare the videos down for You Tube. Sorry about the lost paint. Like i said in the video; this technique will not work on that type of can and the clog occurs down inside the dip tube as well as the nozzle.
11:10 ... the trick may not work but they can be stored for a long time. I just used a can with the any angle head that has been sitting for years. shook it up and it worked perfectly.
Any idea how I can get a clogged butter spray can to work again? I have several of them. Waste of money to not be able to use them and they are pretty much full.
Spray air in it with air Chuck. While nozzle soaks in acetone. Light spray of carb cleaner in nozzle also works. Pick off paint of nozzle with finger nail also.
Air chuck is common vernacular for the device that attaches on the end of an air hose and is used for inflating tires (and other things). It’s what you press against the Shrader valve to get air into a tire.
Of course Rustoleum has their new and improved All Position spray can that sprays paint in any position including upside down. I actually have a clogged one that ONLY sprays in the upside down position. It's a Brave New World.
Well, that does work but you are losing propellant. You won't get all the paint because you lost a lot of propellant from doing this everytime. What about using WD40 to clear the clog?
Clear the tube and tip, but also flush the tip and nipple after each use with spray carb cleaner. Swap the nozzles and spray the cleaner at the paint can nipple. Works perfectly, but don't get spray in your eyes.
hi, my spray paint has a problem of leaking, i bought an Amstradam acrylic (water based)paint (for my school art works) and if I'm correct i think i haven't had used it for about less than 6 months and when i opened it today, it wouldn't work, it worked for the first one minute and then stopped, strangely making noises and its leaking out, i tried your method of spraying it upside down, its still not working, can you please help me? thanks!
Well Beau, my technique is to prevent a clog not unclog a clog. It's too late for my way. There are a lot of vids on here to show you that. Thanks for watching and for your question. Please check back for more tips.
Amazing video!!! CRAIG I have 2 maybe 3 questions and they're very important. First off thank you for sharing the knowledge of the aerosol it helps understand it and what not to do! Questions ------- 1. If I bought a six pack of any angle cans how long would they last till the stem clogs with the solid or would they not clog if never used? 2. There are cheaper cans for 1 dollar compared to the any angle spray cans from rustoleum, and they are very watery. If shaken it would make the solid lighter couldnt we not shake them to keep them more opaque? Thanks Craig!!!
Nice history channel clip. Thanks was looking for unclogging a spray can 12 minutes ago. The old turn that can upside-down trick.. Thanks. It looks like if the deed is already dun you can shoot air into the can several times till it unclogs, drill the sprayer and the can out to fit a solvent can "red straw" and you may get lucky.. still hunting for more methods.
If you've got a clog in the pickup tube on the inside of a spray can, use an automotive valve stem to make an attempt to clear the clog. You can use this technique on a variety of spray cans that have a propellant inside of them whether it's paint, expandable insulating foam, hairspray, adhesives, etc-etc-etc. More on this later. I'll issue this warning - a manufacturer would never recommend this technique I'm sure but it is useful for salvaging a can if you're willing to accept the risk of having something happen. I recommend wearing safety glasses and taking the proper precautions to prevent injury to yourself as well as to protect your property. Remember that a lot of propellants are highly flammable. What's inside the can could blind you if it gets in your eyes and could certainly damage your lungs if you ingest it. There's also the potential to get sliced open and bleed badly if the can were to burst. Note that not all cans will tolerate 100 PSI. Some of the smaller cans are made out of Aluminum instead of steel and might only hold 15 to 20 PSI so be careful what you pressurize and by how much. What you're doing is all on you! Now back to the technique. Since it has been done many times before and it's easier to watch it than explain it go to the following channel: sixtyfiveford The video you need to watch is this one: Fix Clogged Spray Paint Cans The rest is up to you. Best wishes! 🤔👍🏻🇺🇲 - Max Giganteum
Great job, basically what he's secretly implying there, is the propellant dilutes the paint, so putting it back in a can & refilling with more propellant will dilute the paint mixture. Imagine how diluted two colors mixed together would be & adding liquid repellent gas to it. Maybe it is better to add air sometimes in refillable cans. Any thoughts?
I think Rustoleum introduced the Any Angle feature just so their cans would go dry more often and hence sell more cans. FYI - I've had the Any Angle type clog in vertical but STILL WORK UPSIDE DOWN!
Thanks for the useful information! This stuff should be printed on the side of every can so consumers can make the best use of their product. But of course, the corporations would rather have use spend a bit more for a replacement can. It's all about making more money for them.
I thought everyone knew that. But very well done. I always save the nozzles from the old cans in case I get one that clogs, and they do clog no matter what you do.
Well I have had different experiences. If I do this trick they do not clog. They can also clog below the tip and in the tube, so saving the tip does nothing...
S o you are saying that we have to boil the spray can in water. Please help me i am i a hurry to unclog my spray can because i am working on a project .please help me .
You can buy new nozzles for that. Or just do as I have suggested and keep your money in your pocket. I know you were kidding about the question of boiling the can. ;-)
I've lost my time. Nothing new. I do agree completely with Jade sky. Now, I have a lot of clogged spay bottles. What to do? well, to pitch'em out to the trash.
So how common is it for a can to lose its propellant in a can of product like WD40 when the can is still nearly full? If the propellant is lost, in a can that is still nearly full, is the can still under too high of pressure to punch a hole in and remove the product/lubricant?
Not really sure. I've never had that issue. I'm sure it's possible though. Solvents will constantly try to escape like a wild animal. They will find their way out eventually. If so, you could release all of the remaining pressure from the top, just to be sure and safe, then poke a hole in the bottom of the can to capture the remaining unused product in a bottle. The only challenge then would be to apply the lubricant to the area needed. Spraying with a directional straw is most convenient for application. You could use a brush I suppose. See this You Tube link by my "brotha from another motha" to see how its done. He uses paint but the same technique could be done with a solvent. Please be careful and use extreme caution. Be sure that there are no open flames or ignition sources near. I'll post the link next below. Thanks for the great question. I hope this helps.
shoot!!! I can't find the link now. The guy used a nail, a plastic cap, and a wooden handle to create a tool to release the pressure all the way. Then he poked a hole in the bottom of the can to drain the product out. Maybe you can have better luck trying to find it here on You Tube.
I slowly push an ice pick into the side or bottom of the can.The taper on the tip seals the hole as it goes in, you can then back off the pressure on the ice pick slowly letting remaining pressure out of the can, then you are safe to drain the can.
Turning the can upside down and spraying until it runs clear is the directions on virtually every can, no mystery fix here.That being said, there are still times when a can left sitting for months will not work, even if you follow the directions.
The liquid propellant does actually boil when the valve is opened. When the pressure drops the liquid propellant begins to boil into a vapor which keeps the can pressurized at a constant pressure (based on the temperature and the vapor pressure of the liquid propellant). Sometimes you can actually hear it boiling when you hold the valve wide open. After you have been spraying for a while all the boiling of the liquid cools it down and thus reduces pressure. Unfortunately, this also chills the paint so that it dries slower. The chilled paint can also cause moisture in the air to form condensation which can disfigure the paint surface and can cause adhesion problems with subsequent coats of paint.
It isn't boiling... this a complete misuse of the word. What's really occurring is expansion. Liquid to gaseous state. Heat or cold is an irrelevancy - the purpose of the propellant is to push the paint out of the can. Yes, heat or cold can influence how paint flows from a nozzle and with separation, adhesion, drying time, etc-etc-etc but the primary purpose remains the same. If you really want to do yourself a favor, make sure the average temperature of the can, what you're going to paint and the environment you're painting in is around 70-75° F. Prep your surface! Properly shake the contents. Take your time painting. Use long even strokes at the correct angle and distance with proper overlap at a healthy rate of application and you'll be successful nor will you have to worry about what's going on inside the can. Just give it a good 2-3 second shake about every 15-20 seconds. Allow the paint to flash between coats. Develop and retain good habits... you'll be a pro in no time. Best wishes! 👍🏻👨🏻🏭🇺🇲 - Max Giganteum
@@MaxGiganteum Let’s ignore the definition of the term “boil”. It doesn’t really matter here. I was probably creating a distraction. My fault. My point was that rattlecan paint quickly drops in temperature which can cause problems in humid environments. The paint comes out cold. It will condense water in the atmosphere and give a poor paint job. I lived in San Francisco and the Pacific Northwest where the damp is a huge pain in the ass. Recognizing this and mitigating temperature and humidity gives better results. As for the physical chem involved with Boyle’s law and the adiabatic process that explains the refrigerant effect of aerosol propelled paint, I don’t think understanding this matters. The point is that rattlecan paint starts to get very cold. Cold paint is bad in damp environments. Painting in damp environments is not ideal, but it’s difficult to argue with the climate in Washington.
@@NoahSpurrier I get you on the damp and/or wet thing... I spent 30 years in SW Washington. My solution was to never paint anything in the Winter. Or the Spring. Or the Fall. (ROFL!) Kidding aside, I did find a high level of success by pre-warming everything and being in an extra dry environment. I could paint year round in the shop with the wood stove cranking out tons of heat if necessary. Slowing down the process does help - I mean thinner coats with more coats for coverage with extra stoppage time between coats. It takes patience but I would combine painting with other tasks so it was easy to just set a timer and dust on another thin coat when it went off. Heat soaking the can the entire time works too - just don't let it get too hot! In all reality, the real solution was to avoid spray cans where practical. I used a bona-fide HVLP spray gun thus avoided propellant issues. If paint matching or supply was an issue, I would literally bleed off the propellant from a spray can and transfer that paint into the gun. Sometimes I used an airbrush gun too. Best wishes! - Max Giganteum
Thank you for researching this and explaining how it all works. I think I have some cans that have semi dried up paint in the straw. So far, nothing I try will relieve this clog. At least now I can save any new cans.
Thanks. That was my first video. It annoyed some people. I doubt I’ll do it again. I like stuff like that but recognize that most do not. My future vids will stay on task. Thanks for watching and appreciating my e presiding. Keep checking back for new videos.
Craig Shotwell I think you should keep the history stuff but provide a timestamp in the description that people can click on to skip it. Best of both worlds. Like I said, I was really really glad I watched the history section. I feel like I actually learned something.
Great job, basically what he's secretly implying there, is the propellant dilutes the paint, so putting it back in a can & refilling with more propellant will dilute the paint mixture. Imagine how diluted two spray paint colors mixed together would be & adding liquid repellent gas to it. Maybe it is better to add air sometimes in refillable cans if it comes out ok. Any thoughts?
Craig, awsome video. I got a lesson history, mechanical engineering and chemical engineering all in less than 12 minutes! Great tip re: spraying upside down til clear. Thank you!!
its good to learn from others mistakes - [i had a clogged spray can, me thought of taking the remaining paint out and using a brush to paint. BAAAD idea. Almost got evicted from my rental]

First of all I love the history lesson and the accordion music. Being an accordion player, you definitely got my attention. but all of that aside, thank you for a most amazing and helpful instructional video. You are fantastic!
I’ve used compressed nitrogen to blow the clog back into the can with about 30% success.
Nicely done. I like your approach of first presenting an actually researched underlying basis for the main topic.
Thank you. Maybe I got a tiny bit carried away. I like giving credit where credit is due.
Knew the upside down trick, but not all the other info and history! Thanks for including that!
Thanks. It was fun researching and making.
an old trick, it only helps a little, they will still clog
Trick? Been a while since I bought a spray can, but that was always included on the can's instructions.
Brilliant! Thank you so much Craig for posting this informative video about a "classic" problem with spray cans that fail before being empty - you should teach, your video has very practical application and saves a lot of money (and frustrations, for me at least), Ciao, L

Great video man, but my problem is still not solved antiperspirant deo can stopped working BECAUSE I shook the can! Why and how do I fix it?

Hmm. Hair spray. Did you try my method after using? Not sure if it will work on hair products or not. Do t use um. Thanks for watching anyway.
STORE the hair spray can upside down--it keeps the spray nozzle working much longer.
And dont throw away bu return dead half used cans to big box improvement stores. This campaign will encourage the manufacturers to provide spare nozzles with new cans.
i tried blowing 100 psi into tip and it worked. Just with a ryobi inflator, not car part, and it put some pressure in it.
unexpected, but basically more than I was looking for, appreciate the history and lesson. I'm a graffiti artist.
SPOILERS: The video starts at 9:15 and the secret is turning the cam upside down and giving it a few sprays before you put it away.
very informative and up to the detail of "why" and "how" things work
well done production - the quality adds to the lessons, makes them more interesting
Modern rustoleum cans can’t use the upside down spray trick as they spray from any angle now. What were they thinking? That was a feature. Is there any way to unclog them with the new cans?
Man, 12 minutes just to find out all you have to do is follow the instructions printed on the can?

But I still liked the video on the history of spray cans.
2 thumbs up.
Question: What can a person do with a clogged can of 3M Super77 spray adhesive? Great video BTW!
Very familiar with that product. Doesn't matter what the contents. Once clogged there is no remedy that I am aware of. Sorry. Just do your best to avoid.
The old turn that can upside-down trick... .. . Good one you got me!
Any other graff heads here!? I remember watching this year’s ago
Good explination but that method doesn't work on cans that will spray product in any direction. (ie. upside down).
Sounds like clearing the tube by spraying upside down and then storing it upside down to keep the "product" from the bottom might be a good idea.
nice long video, pretty well informed. my problem is that new big white nozzle you showed at the end. I've shaken it s bunch and still nothing comes out. it's clogged. the can says use mineral solvent for the nozzle, but it still doesn't work.

You use the word "misnomer" when you should say "myth". Not the same things. Good video.
He took 12 minutes to tell me what it already says on the can…🤔 contractor Craig, you’re fired
Really informative video, but do you know how to unclog a can that's already clogged??
Cooper Epps Nope. Sorry. Do you? I'm afraid the horse is out the barn my friend.
Spray air in it with air Chuck. While nozzle soaks in acetone. Light spray of carb cleaner in nozzle also works. Pick off paint of nozzle with finger nail also.

True true my friend. I actually mentioned that at the end on the video. You can still get the other kind. Only buy that when needed.
Well done. I now know more than before. I need to work on the 6-8 cans clogged & full of paint.
I really hope you see my message, but which propellant would be best for non flammable pepper spray?
Fascinating ! Great job. Thank you.
11 minutes to say what is written on the lable of every spray can I've ever seen. 👎
this didn't explain how to un clog a can that's never been used
This was awesome and detailed thank you very much
How about hairspray? Aerosol can hairspray?
Won't spraying upside down also use up propellant?
Well, that does work but you are losing propellant. You won't get all the paint because you lost a lot of propellant from doing this everytime. What about using WD40 to clear the clog?

Hey Hampton. Yeah this was my first. Thanks for watching.
How can you tell if a valve is the type that will spray at any angle?
Awesome thank you for the tip and information
Hello sir can i connect a nosel to it and refil it
amazing video , Im student thank you

Well Beau, my technique is to prevent a clog not unclog a clog. It's too late for my way. There are a lot of vids on here to show you that. Thanks for watching and for your question. Please check back for more tips.
Craig Shotwell well, i couldn't find one that relates to mine but thanks! Cheers.
With these few pointers I will be the best graffiti artist ever
Nothing i hate more than a clog when its time to sniff some paint
Amazing video!!! CRAIG I have 2 maybe 3 questions and they're very important. First off thank you for sharing the knowledge of the aerosol it helps understand it and what not to do!
Questions
-------
1. If I bought a six pack of any angle cans how long would they last till the stem clogs with the solid or would they not clog if never used?
2. There are cheaper cans for 1 dollar compared to the any angle spray cans from rustoleum, and they are very watery. If shaken it would make the solid lighter couldnt we not shake them to keep them more opaque?
Thanks Craig!!!
very educative.thank you regards
Amazing, you're the man!!! :):)
Thanks Rex!!! I really appreciate the compliment!
Nice history channel clip. Thanks was looking for unclogging a spray can 12 minutes ago. The old turn that can upside-down trick.. Thanks.
It looks like if the deed is already dun you can shoot air into the can several times till it unclogs, drill the sprayer and the can out to fit a solvent can "red straw" and you may get lucky.. still hunting for more methods.
I have used the method of clearing the tube of paint, but in many cases I run out of propellant before I run out of paint when I use it the next time.
If you've got a clog in the pickup tube on the inside of a spray can, use an automotive valve stem to make an attempt to clear the clog. You can use this technique on a variety of spray cans that have a propellant inside of them whether it's paint, expandable insulating foam, hairspray, adhesives, etc-etc-etc. More on this later.
I'll issue this warning - a manufacturer would never recommend this technique I'm sure but it is useful for salvaging a can if you're willing to accept the risk of having something happen. I recommend wearing safety glasses and taking the proper precautions to prevent injury to yourself as well as to protect your property. Remember that a lot of propellants are highly flammable. What's inside the can could blind you if it gets in your eyes and could certainly damage your lungs if you ingest it. There's also the potential to get sliced open and bleed badly if the can were to burst. Note that not all cans will tolerate 100 PSI. Some of the smaller cans are made out of Aluminum instead of steel and might only hold 15 to 20 PSI so be careful what you pressurize and by how much. What you're doing is all on you! Now back to the technique.
Since it has been done many times before and it's easier to watch it than explain it go to the following channel:

Excellent video thank you.
I waited twelve minutes for that?
Great job, basically what he's secretly implying there, is the propellant dilutes the paint, so putting it back in a can & refilling with more propellant will dilute the paint mixture. Imagine how diluted two colors mixed together would be & adding liquid repellent gas to it. Maybe it is better to add air sometimes in refillable cans. Any thoughts?
I think Rustoleum introduced the Any Angle feature just so their cans would go dry more often and hence sell more cans. FYI - I've had the Any Angle type clog in vertical but STILL WORK UPSIDE DOWN!
Different input point in the pickup. You should actually be thankful! 🤔👍🏻🇺🇲

Thanks for the useful information! This stuff should be printed on the side of every can so consumers can make the best use of their product. But of course, the corporations would rather have use spend a bit more for a replacement can. It's all about making more money for them.
dude Nicely Done. you could have a show
I thought everyone knew that. But very well done. I always save the nozzles from the old cans in case I get one that clogs, and they do clog no matter what you do.
Well I have had different experiences. If I do this trick they do not clog. They can also clog below the tip and in the tube, so saving the tip does nothing...
I have never had one clog in the tube, only in the nozzle. So if you do as they say, no problems.
S
o you are saying that we have to boil the spray can in water. Please help me i am i a hurry to unclog my spray can because i am working on a project .please help me .
You can buy new nozzles for that. Or just do as I have suggested and keep your money in your pocket. I know you were kidding about the question of boiling the can. ;-)
No the problem is not of nozzle its in the pipe inside the can. please guide me what to do
I've lost my time. Nothing new. I do agree completely with Jade sky. Now, I have a lot of clogged spay bottles. What to do? well, to pitch'em out to the trash.
So how common is it for a can to lose its propellant in a can of product like WD40 when the can is still nearly full? If the propellant is lost, in a can that is still nearly full, is the can still under too high of pressure to punch a hole in and remove the product/lubricant?
Not really sure. I've never had that issue. I'm sure it's possible though. Solvents will constantly try to escape like a wild animal. They will find their way out eventually. If so, you could release all of the remaining pressure from the top, just to be sure and safe, then poke a hole in the bottom of the can to capture the remaining unused product in a bottle. The only challenge then would be to apply the lubricant to the area needed. Spraying with a directional straw is most convenient for application. You could use a brush I suppose. See this You Tube link by my "brotha from another motha" to see how its done. He uses paint but the same technique could be done with a solvent. Please be careful and use extreme caution. Be sure that there are no open flames or ignition sources near. I'll post the link next below. Thanks for the great question. I hope this helps.
shoot!!! I can't find the link now. The guy used a nail, a plastic cap, and a wooden handle to create a tool to release the pressure all the way. Then he poked a hole in the bottom of the can to drain the product out. Maybe you can have better luck trying to find it here on You Tube.
I slowly push an ice pick into the side or bottom of the can.The taper on the tip seals the hole as it goes in, you can then back off the pressure on the ice pick slowly letting remaining pressure out of the can, then you are safe to drain the can.
Turning the can upside down and spraying until it runs clear is the directions on virtually every can, no mystery fix here.That being said, there are still times when a can left sitting for months will not work, even if you follow the directions.
Will this work for hairspray as well?
How does an any-angle aerosol can work?
Excellent tip many thanks !
The liquid propellant does actually boil when the valve is opened. When the pressure drops the liquid propellant begins to boil into a vapor which keeps the can pressurized at a constant pressure (based on the temperature and the vapor pressure of the liquid propellant). Sometimes you can actually hear it boiling when you hold the valve wide open. After you have been spraying for a while all the boiling of the liquid cools it down and thus reduces pressure. Unfortunately, this also chills the paint so that it dries slower. The chilled paint can also cause moisture in the air to form condensation which can disfigure the paint surface and can cause adhesion problems with subsequent coats of paint.
hmm
It isn't boiling... this a complete misuse of the word. What's really occurring is expansion. Liquid to gaseous state. Heat or cold is an irrelevancy - the purpose of the propellant is to push the paint out of the can. Yes, heat or cold can influence how paint flows from a nozzle and with separation, adhesion, drying time, etc-etc-etc but the primary purpose remains the same. If you really want to do yourself a favor, make sure the average temperature of the can, what you're going to paint and the environment you're painting in is around 70-75° F. Prep your surface! Properly shake the contents. Take your time painting. Use long even strokes at the correct angle and distance with proper overlap at a healthy rate of application and you'll be successful nor will you have to worry about what's going on inside the can. Just give it a good 2-3 second shake about every 15-20 seconds. Allow the paint to flash between coats. Develop and retain good habits... you'll be a pro in no time. Best wishes! 👍🏻👨🏻🏭🇺🇲

@@MaxGiganteum Let’s ignore the definition of the term “boil”. It doesn’t really matter here. I was probably creating a distraction. My fault. My point was that rattlecan paint quickly drops in temperature which can cause problems in humid environments. The paint comes out cold. It will condense water in the atmosphere and give a poor paint job. I lived in San Francisco and the Pacific Northwest where the damp is a huge pain in the ass. Recognizing this and mitigating temperature and humidity gives better results.
As for the physical chem involved with Boyle’s law and the adiabatic process that explains the refrigerant effect of aerosol propelled paint, I don’t think understanding this matters. The point is that rattlecan paint starts to get very cold. Cold paint is bad in damp environments. Painting in damp environments is not ideal, but it’s difficult to argue with the climate in Washington.
@@NoahSpurrier I get you on the damp and/or wet thing... I spent 30 years in SW Washington. My solution was to never paint anything in the Winter. Or the Spring. Or the Fall. (ROFL!) Kidding aside, I did find a high level of success by pre-warming everything and being in an extra dry environment. I could paint year round in the shop with the wood stove cranking out tons of heat if necessary. Slowing down the process does help - I mean thinner coats with more coats for coverage with extra stoppage time between coats. It takes patience but I would combine painting with other tasks so it was easy to just set a timer and dust on another thin coat when it went off. Heat soaking the can the entire time works too - just don't let it get too hot! In all reality, the real solution was to avoid spray cans where practical. I used a bona-fide HVLP spray gun thus avoided propellant issues. If paint matching or supply was an issue, I would literally bleed off the propellant from a spray can and transfer that paint into the gun. Sometimes I used an airbrush gun too. Best wishes!

Most epic video of all time ever.
Ha! You're funny. Stay tuned I will be posting more epic productions !!!
Thank you for researching this and explaining how it all works. I think I have some cans that have semi dried up paint in the straw. So far, nothing I try will relieve this clog. At least now I can save any new cans.
At first i was annoyed you were playing the history part first... but it ended up being really informative and im glad you did it.
Thanks. That was my first video. It annoyed some people. I doubt I’ll do it again. I like stuff like that but recognize that most do not. My future vids will stay on task. Thanks for watching and appreciating my e presiding. Keep checking back for new videos.
Craig Shotwell I think you should keep the history stuff but provide a timestamp in the description that people can click on to skip it. Best of both worlds. Like I said, I was really really glad I watched the history section. I feel like I actually learned something.
Bloody nice one mate, thanks
Great job, basically what he's secretly implying there, is the propellant dilutes the paint, so putting it back in a can & refilling with more propellant will dilute the paint mixture. Imagine how diluted two spray paint colors mixed together would be & adding liquid repellent gas to it. Maybe it is better to add air sometimes in refillable cans if it comes out ok. Any thoughts?
That’s has been such a great video! Thank you for doing such a wonderful job explaining it.
Excellent! Thank you!
Well done much appreciated
Craig, awsome video. I got a lesson history, mechanical engineering and chemical engineering all in less than 12 minutes! Great tip re: spraying upside down til clear. Thank you!!
WOW! That was very helpful and informative. I hate it when someone says just do this with no explanation. Your whole video was just cool. Thanks
was wondering why i couldnt clear some cans with the upside down clearing trick THANKS!
good tips, and history lesson always interesting... thanks.
Thank you Frank. I love history and feel it’s important to give credit where credit is due. Please check back for future vids
So if I want less liquid coming out as spitting and more vape come out as a smoke I increase the pressure in the can by adding more gas inside?
I love learning something
its good to learn from others mistakes - [i had a clogged spray can, me thought of taking the remaining paint out and using a brush to paint. BAAAD idea. Almost got evicted from my rental]
