Stanley Dispensing Gun Cleaner Solvent Mixture Dissolving Uncured Polyurethane Foam Polyurethane Insulation Foam Aerosol Can Bottle

Works great. But since this is basically just paint thinner behind compressed air you can use it for a variety of cleaning because the cans come with a simple spray nozzle that works like any old spray can (in addition to its ability to have a dispensing can screw onto it for compressed cleaning). I'll definitely be keeping at least one of these cans on-hand in the future. For reference, I was able to clean my foam dispensing gun about 3-5 times, very thoroughly, with one can.

I ran out of cleaner for my guns, which I had used as filling material spray, making them useless. I tried using this cleaner alone without success due to the time since the spray gun's last use. If I had it available immediately after using the filling material, I do not doubt that it would work extremely well. My only option was to either throw away the expensive guns or attempt to remove the buildup inside them. I decided to try and repair them by Removing These Cans FROM THE AREA SINCE THEY ARE EXTREMELY FLAMMABLE. While wearing safety glasses and other protective gear, I used my small torch to heat the spray gun barrel and the opening where the can normally goes. Next, I used a thin, non-bending wire to clear both ends, pointing them away from my face, because the heat and any wet material inside the gun will blow out BOTH ends when pressing the gun handle. After doing this a few times, I cool the gun under cold water, then use this cleaner. Slowly, it loosened up the material and functioned properly again. The guns are so expensive that it is the only reason I attempted. It's much wiser to keep this cleaner on hand and clean the gun immediately after the last use. I'm not recommending what I did. Rather, I am only explaining what I did and help people remember to have plenty of this cleaner on hand before starting a new project.

Easy to use, cleaned the foam sprayer completely with little effort.

worked as expected.

Great product!

Works as it should. It attached to the spray gun smoothly and formed a good seal, unlike other brands I’ve used. Some brands leaked as I attempted to attach them. I was able to clean the gun barrel to make sure no foam was inside. Of course, it’s important to clean the equipment as soon as you’re done spraying.

Not a lot to say other than "it worked, it fit, it cleaned and didn't leak". While this is great for giving a foam gun a long life, having aerosol acetone (it's just acetone, far as I know) is handy for all sorts of cleanup. Just be aware that you want good ventilation, and acetone isn't a do-it-all product - it can remove some paints and melt some plastics. All of these gun cleaners comes with a spray tip that fits into the gun attachment to use it as a spray can - the tip tucks into a little holder in the top, and has a little molded plastic lanyard so you don't lose the tip. So just take care not to break the "lanyard"!

This has two ways to apply. It can be screwed into an applicator gun and sprayed through it to get the gun completely clean when done. It also has a spray nozzle attached with a tether so you don't lose it. Spray like an aerosol can with the nozzle to get a partially used foam can tip clean. Nice!
