How to Refill an Aerosol Spray Can (Like Carb Cleaner, WD40, etc)

hold can upside down while charging so only air goes into can rather than spilling liquid. Nozzle had a straw that goes to bottom of can.

Wait! Unlimited AIR HORNS!!! THANK YOU CHRIS <3

Just to let anyone know. You don't have to depress the nozzle on the can. It works much like a check valve. Air goes in, not out, "unless it leaks". Just place the valve stem over the nozzle tightly. It will work every time. Been doing his for 20 years. (note) I always use a rubber valve stem. Much safer then any other way.

Just did this on my bladder and now I can pee 20 yards. Many thanks.

This is like the most practical auto channel on youtube, I've learned so much in just a week of being a subscriber!

Chrs fix is by far the best, when you see his videos, makes you feel like he is right next to you guiding you the whole way to get the job properly done

Chris Fixx: I saved $10 refilling this can with air! Chriss Fixx's Dad: WTF happened to my lawn??

Quick tip, butane refill cans come with various tips. There is a fat one that makes the valve stem one work better.

I have done that many times in the past. Works very well. When I do it, I attach a very small piece of vinyl tubing to the air nozzle, then slide the tubing over the tube sticking up on the can, then press down to fill. No Mess.

Don't cut the valve stem so that it doesn't push the spray can straw down. Just hold the valve stem tight to make a seal on the can. The air pressure will still fill the can without pushing down the spray nozzle. Less messy. Or, like someone else said, hold the can upside down.

After soooo many years watching this channel it is NOW YT decides to recommend this video??? 🤦‍♂️ I’m gonna go thru all the videos I can this week!

Another idea if you dont have a compressor or you're worried about safety is to make sure theres zero pressure in your full can and then just pierce a hole in the can and use the liquid inside, you can do this with any aerosol like we do in industrial shops. Brake cleaner and degreaser and carb cleaner all come in big unpressurized drums. The mechanics then fill those plastic pump bottles with with brake cleaner etc and have a spray. So get yourself a pump bottle and just fill it with any flat cans you have

At the bicycle shop I used to work at, they had a bunch of aerosol cans that had been drilled on the bottom, and a tire valve soldered into the hole. You could remove the valve core, and refill the liquid too.

Hi Chris, This is a great idea. A few years ago, I got tired of buying compressed air (computer "duster") at almost $6 per can. I went to discount tire and told them what I was trying to do and they gave me a new valve stem for free. I drilled a small-ish hole in the bottom of an old empty can. (That was the flatest spot, but I can't set the can down properly anymore.) I squeezed the valve stem in and added high pressure epoxy sealant, (made for radiator repair) to bond the rubber to the metal. I've been using it for years at work for cleaning computers and other electronics. It doesn't last as long as a store bought can of duster, but with free refills for life I've probably saved over a $1,000 already. Thanks for the great video!

Pro tip. Turn the cans upside down and refill them. That way no fluid is forced out when refilling.

I just pop a hole and drain it out don't waste anything. This is good info.

6:50 - "I'm not gonna waste it" sprays it again and again

I must say man.... you and Scotty Kilmer are BY FAR my favorite car channels on YouTube! Keep putting out quality content!

I've been watching Chris for years, but I had never seen this video before. This is my new FAVORITE! I have a compressor and about a dozen cans that are completely unused, but with no air. THANKS!!!
