If you have the small toolbox can of EW40 that is empty you can recharge it several times. I've been doing this for years. Simply take the red spray tube and attach it to the can with the most WD40 in it. Press both cans at the same time and it will fill the small can until the pressure equates. Presto the smaller can is back in service. Now its not full but almost 1/2 and you can fill it like this for years!
Aerosol cans aren't filled with air. They're filled with CO2, butane, natural gas or freon (very old cans)… The CO2 leaks out, because it's a very small molecule. I have 40 year old freon charged cans that still spray fine, because freon molecules are huge. You're not "refilling" a CO2 pressurized can if you put air in. Air is an oxidant, and will gradually degrade most compounds, especially paints and spray adhesives.
This was my "trick" as well since the 80's, certain manufacturers either didn't use enough propellant or the pickup tube inside the can was nicked and allowed too much gas to escape during normal use. This is definitely a way to get out almost all of the product. I'm sure you have helped a lot of people to get their moneys worth. 👍🏻
Awesome tip man! Tried this with the valve from an old mountain bike inner tube and one of those standing up bicycle pumps. No problemo doing it by myself. Worked like a charm on my alost empty air duster cans. Feels great knowing that I can puff away w/o seeing my money go with the wind. :D Many thanks. Two of the cans did not have the male plastic pipe sticking up (that male part was in the spaying nozzle cap), so I just cut a short bit of the plastic pipe that came with the air duster can and put that into the hole. It sealed well enough to put as much pressure as I was comfotable with (heard a slight creaking sound around 60+ psi, and stopped).
OMG! I love it. I spent my life throwing out cans with lots of remaining fluid in them, whatever it is, paint, WE-40, lubricants, you name it. I am going to try it. THANK YOU FOR SHARING IT.
Thank you for the excellent tip! WD-40 cans have been a problem over the years to the point that I would puncture the can with an awl and drain out the remnants. Re-pressurizing the can is absolutely the way to go.
Another thing you can do in a pinch, is put the can in a freezer for a while, then press down on the cap after it's had time to chill and it will pull in a bit of air. Not as good as using a compressor, but it will allow you get a little more out.
I have never in my many years seen a WD-40 spray can run out of content and still have pressure left in the can. They always and I mean always run out of pressure while there is plenty of oil in the can. Always!!
my air compressor came with the ‘needle’ to fill up soccer balls, etc. just the right size to stick in the middle of the spray can nub, push in, and air goes into the can
@@Scottocaster6668 yep, you do not even have to press down hard as the air flows backwards into the can because the cans valve is designed to keep contents in. i learned from this video that 100psi is ok. i stopped at 30psi (the can gets hard at that point and can not be squeezed) and sometimes needed 2 or 3 refills. you can hear the can contents bubbling as air from the compressor enters the can through the nozzle
@J D no crossing needed. air compressors have a dial you can turn which sets the max pressure that comes out the end of the hose. - just turn it to 100psi
@J D I wouldn’t recommend doing this either by my method, or the method presented in this video without an inline pressure gauge/regulator. I am certain one can get one for under $10 from Harbor freight or so.
Great green tech to NOT waste anything on our planet, that has already been created. Some dummies will ask (does that also work for (fill in product name) as if the can colour or liquid inside makes a difference). But speaking of wasting, at 2:24., we GET it, no need to half empty your remaining fluid to hammer home that you pumped air into the can. PS, I used to service compressors, and today, still have units for sale- from 5 - 125 HP. We know air. Thanks for a great savings idea! 👌
Thanks for great idea. Was always running out of WD-40 pressure so I tried your technique today. Had to cut about 1/4 of rubber off the base of valve stem so inside brass tube would press on on can stem. You have to use this valve stem to press open can white stem to get air pressure into the can. Air pressure along is not enough to overcome the can stem valve.. Your technique works, thanks a bunch.
I tried this with a random seal cut from a rubber hose and a standard upright bicykle pump. Pressing the pump against the rubber was enough. Lovely bubbling sound inside the can. Pressure wants to go from higher to lower. The stem is a valve. Pressing it gets messy.
Love these videos with quick fix suggestions. I had no idea a valve stem could be used to pressurize these cans. I don't know how many times I've picked up a can of something from my shop that was still half full of whatever only to find that it wouldn't spray and have to throw it away. I'll be certain to try this one out. Thanks for the tip
Great idea.. I clean spray paint can values by turning the can upside down and spray until nothing but air but find that I end up over time with paint left in the can and out of air. This method will allow me to utilize the complete can of paint.
The number of cans I have thrown into landfill over the last 4 decades, what a genius solution to use up all that product! Nice specific instructions too, 90psi, without that, I would no way attempt, thank you.
Thank you for a straight forward video without lots of gabbing about other things that don’t matter. I have some dead air cans I’m going to try this on.
Yes, it is very explosive to put oxygen in the can with a very flammable liquid. That is the reference to Nobel right? If you want to refill, you should use pure nitrogen and not air.
This is pretty cool but as previously mentioned, i just lay the can on its side and stomp on it. Initially, there is hardly any pressure in the can so it crushes quite easily. This raises the pressure inside the can just enuff to get that last little bit out. Crude, but effective.
What a GREAT idea :-) Thank you - I have 3 cans saved up with a fair amount leftover without pressure. I was just about to cut them open to save the oil. Re-pressuring is so much better !! Thanks again - Ted

get an air gun with a rubber tip, push down on the nozzle of the can, put the rubber tip firmly against the opening in the nozzle then squeeze the trigger on the air gun to transfer air though the now open nozzle in the can. I do this all the time.
Fabulous method of restoring pressure in aerosol cans that have lost pressure! Probably could use this technique with aerosol paint cans too. Thanks for showing us!

That warning would be right next to the ubiquitous Proposition 65 label.

Thanks Dan....I was looking on ebay but only found the core, then I put valve stem in the search engine and bingo!! Amazing the difference in one word!
I cut the cans off at the top and save the material inside. If paint can, I save the little round marbles too. Save the can, put thinner in for the little paint brushes (oil base) - too lazy to clean them.
This has been a long standing history with my experience with WD 40. They should be filled with a butane/ propane mix. This propellant will partly desvolve into the solution that will release as the product is dispensed. I believe they are filled with CO2. Ive had many cans go dead, and have wrote the manufacture of WD and they have sent me replacement cans, so koodo's to them, I appreciated that they addressed my issue. I have now 4 cans of WD with plenty of product in the can, but no propellant to extract it I think I will try this method, but with propane/ butane mix and see if this improves the performance of the dispensing.
Great idea, I've done it using a rubber tipped blow gun, on the spray head, just push it down and end then hit it with air, also subbed, I like people who solve problems that most people would just buy new, thanks brother 😎😎
Be careful! "Oil (hydrocarbons) in the presence of oxygen under pressure burn violently (combust, explode)." Ask any welder why you should never oil an oxygen regulator valve. I know, the atmosphere contains little more than 20% oxygen, but under certain conditions, re-pressurizing your can of WD-40 could be life-changing...for the worse. One of the propellants originally used in WD-40 aerosol cans was butane, but to reduce the flammability of WD-40, the manufacturer switched to CO2 (carbon dioxide) or other gases that don't support combustion. Using air to pressurize hydrocarbons like oil or WD-40 can be very dangerous.
It takes about 380 psi to ignite oil (diesel). You would want to avoid static when filling. But 70 psi at room temperature isn't going to hit ignition temperatures, and pressure.
The vapor pressure of the WD-40 “active ingredients”, i.e. the ingredients susceptible to oxidation and combustion, are insignificant to addition of a few pounds of air pressure to the can at normal environmental temperature and conditions. It shouldn’t blow up, or ignite. Try it and see!
yea, but what isn't dangerous in this world.....give the can some air and use the product you paid for with your hard earned dinero......the odds of blowing yourself up are less than the same odds of dying from covid........which is another bit of scare tactics
I believe this will work ok for most fluids but I would advise not to do this with spray paint. Plain air may cause the paint to clump and start cureing in the can. You would get a splattery messy spray. If you used it soon it should be ok. Though paint not comeing out Is usually from a plugged sprayer & not from inadequate pressure.
Why is it that Americans need a gigantic amount of words and time to explain something that is obvious to any simple mind. To put a bit of air into a bottle is not exactly rocket science but the way it is presented seems to lift it to the level of a discovery worthy of a Nobel prize.
tony emjay you remove the white button part of the nozzle leaving the small tube/steam of the nozzle. The tire valve goes over that small portion seating around the base of the top of the can. It works, and i am so happy, i have just resurrected like 4 old cans of WD40 that had the lubricant still in the cans but no pressure to access it. Before i had to cut the can open and save the fluid that way. This is so much easier..
I found another way to do it but I was unsure about the safety and the pressure. Your video cleared up the question of safety and 90 or so PSI. thank you.
Was just about to post the same thought..... guess that's what 8 1/2 years of breaking down, dismounting, retreading (and/or section repairing), then remounting semi truck tires would do to a person though. Worked my last day in 1986 for Bandag - best retreads around for semi truck long haulers, and our shop had a 1.4% adjustment rate at that.
This is a good one. Another hvkc i came across along the way to build up pressure in pressureless cans is to place it in warm water and slowly increase the temperature close to a boil but you want to be on the conservative side while doing this. To be safe.
Great idea! I'm so sick of these W-D40 cans running out of pressure because they use CO2 instead as a propellant which is better for the environment but sucks for the consumer wanting to use all of the product.
Can you now make a video on how to remove the palm shaped dent from one's forehead after smacking oneself for not thinking of this before?? ...and thank you, btw. Great idea!
Two similar valves, sealed FIRMLY against the nares, (helpful to have assistants), add pressure until anatomical position is attained. Presta...Er no...Schrader!
this happens to me with almost every aerosol spray bottle of stuff...except WD40! I knew there must be a way to recharge these bottles with a wee bit of air pressure. thanks for the tip. PS: companies that purposefully fill their cans with insufficient pressure and make us prematurely throw them out as a way of increasing sales need to be called out. not only are these cans not recyclable, but throwing them out while they're still filled with chemicals is so much worse for the environment that empty cans
The propellant helps pump WD-40 out of the can effectively. The propellant used in WD-40 is carbon dioxide (CO2). CO2 is an inert gas which helps empty the can. Plus, the addition of CO2 reduces the number of VOCs, which helps towards preserving the environment
This is a pure genius fix. And, to think I thought I was clever to do a 1 minute battery charger conversion from those $1 Dollar Tree solar yard lights. This can refill is the best cool fix ever!
I bought a Sure shot sprayer a long time ago, saved me a lot of money over the years. They hold up too. I have one with wd-40 and one with acetone. Depending on what you put in a regular sprayer, the seals often fail.
Interesting video. Is there an ink jet code on the can bottom of that low pressure WD-40 can that you can share? It helps id the manufacturer who'd like to know of defective product
I've actually called them a few times over the years about low pressure cans and given them the codes. Wd40 was a little hesitant but sent me coupons for free cans of Wd40.
sixtyfiveford For all your subscribers.....If you point the spray tip of an aerosol can toward the dot found on top of the can (when one is provided) during use, you will get the most product out when spraying downward.
Jeff K Yeah, the dot is one of the things you learn through trial and error. I don't know why manufactures don't right a little note on the can about it.
I use this all the time. I use a large hyperdermic needle from a farm store and made a tip for it that fits over the plastic needle on the can . I can fill the can with whatever I want, Usually rubbing alcohol. Then I have another plastic tip on a cheep harbor freight air gun , that I use to pressurize the can.
Great idea and video. I go to the Automotive Departments at Walmart and Sam's Club for value stems the few times I did need one and they we're always accommodating :-)
So simple, its like you cant see the forest because of the trees. However it was now pointed out to me. Kudo's to you sir . You don't know how many cans I've have run out of propellant now I can make my problems go away. Thank You Ihor
I quit buying WD40 for the reason that almost every can of it I've ever purchased, stops spraying with a 1/4 or more of the product still inside. Now I buy 3-1 oil in the squeeze bottle
You're using it wrong, like most people do. The can needs to be upright when you spray, otherwise you'll empty more air than lubricant so the ratio gets messed up and you'll run out of pressure before the can is empty. I see it every day. I personally buy 4 gal jugs of wd-40 and a pump spray bottle (you get them in a kit at many hardware stores for about $50 I think) Much cheaper and you'll avoid that problem all together. You can also buy refillable aerosol cans on amazon. Fill it with whatever you want and pressurise it with a compressor or bicycle hand pump. Just don't fill it with acetone or other similar solvents cause it'll dissolve some mechanism inside (probably plastic) and mess it up completely...talking from experience...
I always get the lubricant even if I have to drill or punch a hole in the spray can. Just make sure it has no air inside, as some times spray paint cans still have air but the nozzle is clogged with dried paint, and wrap in a towel to avoid injury. I have done this many times to collect the remaining paint and haven't ever been hurt.
Or you can use a straw or just blow down the pipe like normal people. Like a bit of lint is going to stop a bullet, lolz. You people infuriate most of the rest. Have gun therefore competent. Merica Fuck Yea!
This video has just gotten you another sub👍 I've had to cut open cans before and pour the contents into jars because of them losing air pressure, game changer here for sure, much appreciated
Been doing this for decades, by removing the nozzle & just applying pressure with a standard air compressor with the blow gun held on the tip & depressed to recharge the can!

They aren't pressurised with air. It's usually butane, which is why they often have an inflammable gas warning or it says "propellant: Hydrocarbon" on the can
If it was perfectly safe to fill aerosol cans with inflammable solvents and compressed air don't you think the manufacturers would have tried it? Air is after all significantly cheaper than the stuff they usually decide to put in aerosols. You have made a bomb with an explosive potential significantly higher than that of a stun grenade. It is difficult to ignite the contents, but if they did ignite it could be catastrophic.
It's often the simple, humble process that is quite profound. This is one of those moments. Nicely done!

This may be a good idea, but it leaves me COLD!

I cut the cans off at the top and save the material inside. If paint can, I save the little round marbles too. Save the can, put thinner in for the little paint brushes (oil base) - too lazy to clean them.

I was thinking the same thing... Just tossed a can of carb cleaner with lots left.
Im tired of that happening too
Amazing, I've been tossing my half full cans out all the time!
I've been refilling low pressure cans for years with the rubber tip on my Cornwell air nozzle...valve stem is a good idea Thanks 65ford.
+Joe Boyko (HELLBENT4) Thanks.
wheres your vid ?
Just refilled a carb cleaner can and a PB can I hung on to for who knows why! Thanks!
Nice dude! I've tossed out half full WD40 cans in the past because the propellant was used up. NEVER AGAIN!
Thanks for sharing.
Cheers!
Burnscar81 Awesome. I'm glad you like the video.
It seems like WD40 deliberately uses failure-prone valves to promote more sales.
This has been a long standing history with my experience with WD 40. They should be filled with a butane/ propane mix. This propellant will partly desvolve into the solution that will release as the product is dispensed. I believe they are filled with CO2. Ive had many cans go dead, and have wrote the manufacture of WD and they have sent me replacement cans, so koodo's to them, I appreciated that they addressed my issue. I have now 4 cans of WD with plenty of product in the can, but no propellant to extract it I think I will try this method, but with propane/ butane mix and see if this improves the performance of the dispensing.
Thank You for this. I have 4-5 cans of stuff currently sitting in my garage that are out of air.
Good thing u kept
Never would have thought of this on my own. Great idea man! Thanks
Hey Thanks, I'm glad you liked it.
Great idea, I've done it using a rubber tipped blow gun, on the spray head, just push it down and end then hit it with air, also subbed, I like people who solve problems that most people would just buy new, thanks brother 😎😎
I too have always used rubber tip blow gun
That’s cool dude! I usually just cut the dang can and dump into a container I use for a soak on stuff.
Be careful! "Oil (hydrocarbons) in the presence of oxygen under pressure burn violently (combust, explode)."
Ask any welder why you should never oil an oxygen regulator valve. I know, the atmosphere contains little more than 20% oxygen, but under certain conditions, re-pressurizing your can of WD-40 could be life-changing...for the worse.
One of the propellants originally used in WD-40 aerosol cans was butane, but to reduce the flammability of WD-40, the manufacturer switched to CO2 (carbon dioxide) or other gases that don't support combustion. Using air to pressurize hydrocarbons like oil or WD-40 can be very dangerous.
It takes about 380 psi to ignite oil (diesel). You would want to avoid static when filling. But 70 psi at room temperature isn't going to hit ignition temperatures, and pressure.
The vapor pressure of the WD-40 “active ingredients”, i.e. the ingredients susceptible to oxidation and combustion, are insignificant to addition of a few pounds of air pressure to the can at normal environmental temperature and conditions. It shouldn’t blow up, or ignite. Try it and see!
yea, but what isn't dangerous in this world.....give the can some air and use the product you paid for with your hard earned dinero......the odds of blowing yourself up are less than the same odds of dying from covid........which is another bit of scare tactics
We often spray wd40 on a fire ...don't try that with a refilled can it could be explosive
An oxygen regulator handles 100% oxygen at several hundred to a couple of thousand psi. 20% O2 at 70 psi will not have the same explosive effect.
I believe this will work ok for most fluids but I would advise not to do this with spray paint. Plain air may cause the paint to clump and start cureing in the can. You would get a splattery messy spray. If you used it soon it should be ok. Though paint not comeing out Is usually from a plugged sprayer & not from inadequate pressure.
I was going to do it for wd40 and quad oil...
Just do it right before you are ready to use the paint.
I was making holes in the can to get the WD40 out before I saw this. Thanks
+Elber Galarga I'm glad you found the video.
I just did the same, to be honest I don't mind I prefer to apply it with a brush anyway
Why is it that Americans need a gigantic amount of words and time to explain something that is obvious to any simple mind. To put a bit of air into a bottle is not exactly rocket science but the way it is presented seems to lift it to the level of a discovery worthy of a Nobel prize.
Thank you for this, and WD seems to be one of the ones that does this regularly. Great mech hack, thanks!
does the white nozzle on the WD40 need to be pushed down to insert the air or can it be filled without pressing it down?
tony emjay you remove the white button part of the nozzle leaving the small tube/steam of the nozzle. The tire valve goes over that small portion seating around the base of the top of the can. It works, and i am so happy, i have just resurrected like 4 old cans of WD40 that had the lubricant still in the cans but no pressure to access it. Before i had to cut the can open and save the fluid that way. This is so much easier..
Yes thanks I have thrown out so many cans that lost their air or whatever you use to pump it up
Make sure to use short controlled bursts to avoid overfill or exploding can
Good outhouse advice, too.
I found another way to do it but I was unsure about the safety and the pressure. Your video cleared up the question of safety and 90 or so PSI. thank you.
Liquid wrench always goes flat no more poking a hole and dripping it out!!!
That's what I have always done, too. And I had an air compressor within 25 feet of me when I pierced the cans.
that's a good idea.
That's a valve stem. The core is inside of the valve stem.
Was just about to post the same thought..... guess that's what 8 1/2 years of breaking down, dismounting, retreading (and/or section repairing), then remounting semi truck tires would do to a person though. Worked my last day in 1986 for Bandag - best retreads around for semi truck long haulers, and our shop had a 1.4% adjustment rate at that.

Why didn't I think of that ? Great tip! That's the hack of the year .
Agreed, one of those Duh! moments when you can rebuild a motor but can't think to just refill an aerosol can.
Best hack I've seen in years!
This is a good one. Another hvkc i came across along the way to build up pressure in pressureless cans is to place it in warm water and slowly increase the temperature close to a boil but you want to be on the conservative side while doing this. To be safe.
A good stomp usually gets the last bit out.
Show us your trick
Peg Leg Pete endorses this message.
Great idea! I'm so sick of these W-D40 cans running out of pressure because they use CO2 instead as a propellant which is better for the environment but sucks for the consumer wanting to use all of the product.
How in the world can co2 be better than compressed air???
What do you think Co2 is partner? You probably have a Schrader valve to check the air pressure inside your scull 😄
Just using air makes the internal contents of the can a combustible mixture.CO2 does not
@@MH-WM Love it, and I hope your picturesque comparison makes it to the RUclips Comments humour sweepstakes
Can you now make a video on how to remove the palm shaped dent from one's forehead after smacking oneself for not thinking of this before??
...and thank you, btw. Great idea!
Us one of those sanction cup dent removers that you'll find elsewhere here on FB.
Two similar valves, sealed FIRMLY against the nares, (helpful to have assistants), add pressure until anatomical position is attained. Presta...Er no...Schrader!
this happens to me with almost every aerosol spray bottle of stuff...except WD40! I knew there must be a way to recharge these bottles with a wee bit of air pressure. thanks for the tip.
PS: companies that purposefully fill their cans with insufficient pressure and make us prematurely throw them out as a way of increasing sales need to be called out. not only are these cans not recyclable, but throwing them out while they're still filled with chemicals is so much worse for the environment that empty cans
Dude.....fkn genius!!!!! Just saved me frustration with some spray cans in my garage.
This is the greatest post I've seen in a long time thanks for the clip.
Hey Thanks.
I just took a ball inflating needle and shoved it down the tube. Works great.
You CAN damage your "pee pee valve" doing that ........
lol :) :) :) Not to mention the "OUCH" factor involved .....
The propellant helps pump WD-40 out of the can effectively. The propellant used in WD-40 is carbon dioxide (CO2). CO2 is an inert gas which helps empty the can. Plus, the addition of CO2 reduces the number of VOCs, which helps towards preserving the environment
Ive had cans which have been almost full but no air left, next time i will try this as i got a mate with a compressor 👍
Thank you Jesus🙌. Been looking for something like this for years.
HIS NAME ISN'T JESUS! 😕😕😕
Genius. Absolutely genius! Its these little things that make the difference lol
This is a pure genius fix. And, to think I thought I was clever to do a 1 minute battery charger conversion from those $1 Dollar Tree solar yard lights. This can refill is the best cool fix ever!
Do u have a video about that charger conversion?
I knew it! That's why I kept them around. Thanks!
Dude! I’m always learning new stuff thanks to your channel.... wow... thank you so much you make me smarter.. have a wonderful day and stay healthy...
Fkn brilliant! As soon as I saw this, I went out to the garage and did it. Thanks for the amazing tip.
I bought a Sure shot sprayer a long time ago, saved me a lot of money over the years. They hold up too. I have one with wd-40 and one with acetone. Depending on what you put in a regular sprayer, the seals often fail.
You just gave me back sooo much paint, you just earned a subscriber
Awesome. It's great to meet you.
You horner our fallen heros that gave their lives for humanity.
Just make sure that air supply is dry.
I look forward to trying this with my dead shaving cream cans. I shake them and hear stuff still in it but it doesn’t come out.
If you enjoyed the video THUMBS UP and or leave me a comment! Thanks.
Interesting video. Is there an ink jet code on the can bottom of that low pressure WD-40 can that you can share? It helps id the manufacturer who'd like to know of defective product
I've actually called them a few times over the years about low pressure cans and given them the codes. Wd40 was a little hesitant but sent me coupons for free cans of Wd40.

For all your subscribers.....If you point the spray tip of an aerosol can toward the dot found on top of the can (when one is provided) during use, you will get the most product out when spraying downward.
Jeff K
If you decide to make more aerosol related videos I can offer comment/review to keep you safe and sound.
Jeff K
Yeah, the dot is one of the things you learn through trial and error. I don't know why manufactures don't right a little note on the can about it.
I use this all the time. I use a large hyperdermic needle from a farm store and made a tip for it that fits over the plastic needle on the can . I can fill the can with whatever I want, Usually rubbing alcohol. Then I have another plastic tip on a cheep harbor freight air gun , that I use to pressurize the can.
Best video on youtube ever. ive finally learnt something.
Great idea and video. I go to the Automotive Departments at Walmart and Sam's Club for value stems the few times I did need one and they we're always accommodating :-)
I usually just lay them flat and step on the middle. Compress can, compress air
worked with toothpaste thanks!

Great hack! Costs virtually nothing, so simple to do and so effective.
Hey Thanks.
I recommend setting your regulator to 50lbs. pressure and wearing safety goggles.
and a bomb squad suit if you have one.
@@capnbly hahahaah
Why, you scared?? LOL
Fuck that.
I like it 👍🏻. Hate when there’s still product in the can and no way to get it out!! Sharing with a couple of buddies!!
I punch a small hole in the NO PRESSURE can and pour the WD-40 into a hand squirt bottle... Have done this to a few and works great!
@@geomatrix5452 o
Alright, just had this problem a few days ago. I'll try this. Thank You
You are a gentleman and a scholar! Already saved 1 can (well at least the last 1/4 of it)!
Man that's great! I always have left overs in my spray cans. Thanks for sharing!!
No problem. Hopefully it comes in handy next time.
Thank you for sharing I was just thinking they are such a rip-off and I was going to bunch a hole into the can. Now I will air up my can of WD-40
They are a rip off
Dude! We owe you a beer! Thanks for the video!
Who’s we? 😁
So simple, its like you cant see the forest because of the trees. However it was now pointed out to me. Kudo's to you sir . You don't know how many cans I've have run out of propellant now I can make my problems go away. Thank You Ihor

sixtyfiveford thanks!
Amazing, I would never have thought of this.
I quit buying WD40 for the reason that almost every can of it I've ever purchased, stops spraying with a 1/4 or more of the product still inside. Now I buy 3-1 oil in the squeeze bottle
Two very different lubricants. The 3 in 1 won't clean surfaces like WD does.
You're using it wrong, like most people do. The can needs to be upright when you spray, otherwise you'll empty more air than lubricant so the ratio gets messed up and you'll run out of pressure before the can is empty. I see it every day. I personally buy 4 gal jugs of wd-40 and a pump spray bottle (you get them in a kit at many hardware stores for about $50 I think)
Much cheaper and you'll avoid that problem all together.
You can also buy refillable aerosol cans on amazon. Fill it with whatever you want and pressurise it with a compressor or bicycle hand pump. Just don't fill it with acetone or other similar solvents cause it'll dissolve some mechanism inside (probably plastic) and mess it up completely...talking from experience...
Do you shake up the can every time you spray?
I bought the spray bottle, and just buy a large can to refill it
I took a valve stem from a used bicycle inner tube and it sealed around the plastic stem from the can. Worked out very well.
I just drill a hole in the can and transfer the liquid into a sprayer
Cool... man. Thanks for posting.
@@lazarogerardoviveroschargo3292 they do have pressure left. So normale the moment you drill a hole it goes "pofff" and everything is gone.
That's dangerous, especially if you smoke.
Just punch a hole with a nail at the edge of the top rim.
@@DinkyDoughnut Smoking is dangerous anyway.
Thank you this has happened to me soooo many times and I end up throwing them away such a waste... Never again!!!... Lol
Hey Thanks, I'm glad you liked it.
I always get the lubricant even if I have to drill or punch a hole in the spray can. Just make sure it has no air inside, as some times spray paint cans still have air but the nozzle is clogged with dried paint, and wrap in a towel to avoid injury. I have done this many times to collect the remaining paint and haven't ever been hurt.
No more buying cans of compressed air for $9 to dust off keyboards
Just make sure all of the oil is out of the can before spraying your keyboard...lol
@@TheFarmerfitz I buy cans of compressed air to clean lint out of my gun internals.

This video has just gotten you another sub👍 I've had to cut open cans before and pour the contents into jars because of them losing air pressure, game changer here for sure, much appreciated

Damn ! I wish I knew this years ago, I've thrown out loads of full cans .
Rite after loosing that little tab , thinking of paint spray cans too
I hope you recycle them
Been doing this for decades, by removing the nozzle & just applying pressure with a standard air compressor with the blow gun held on the tip & depressed to recharge the can!
Great idea and one I had not thought about trying. I will try this on spray paint cans also.

They aren't pressurised with air. It's usually butane, which is why they often have an inflammable gas warning or it says "propellant: Hydrocarbon" on the can
Finally I find way fix my damn spray paint.
If it was perfectly safe to fill aerosol cans with inflammable solvents and compressed air don't you think the manufacturers would have tried it? Air is after all significantly cheaper than the stuff they usually decide to put in aerosols. You have made a bomb with an explosive potential significantly higher than that of a stun grenade. It is difficult to ignite the contents, but if they did ignite it could be catastrophic.
Dang, that's awesome! My neighbor has an air compressor. I'm sure he'll love this too! Thanx

I have a half can of WD40 in my garage right now that I was smh about with no air. Wow, videos like this, is why i love RUclips. Thanks bro!
