As the solvent makes contact with the foam, it will begin to soften it and you can then wipe it off with a clean damp cloth, repeat the process if necessary. Next, you need to wash your hands and skin with warm soapy water and ensure that all of the foam has been removed.

Consider Shaving Your Hair

Apply some shaving cream to the affected area, wet your razor, and then carefully start to shave the hair off, moving in the direction of the hair. Be sure to clean the razor in hot water to remove any buildup of foam and continue to remove the dried spray foam from your skin.
Oil and Baking Soda

Most of the dried foam should come off, however, if there is still some left, repeat the process until all the foam has been removed.
Pumice Stone, Nail File or Emery Board
If you are going to make use of a nail file or emery board, make sure it is a washable one. Maybe you do not have such a thing, then you can also use medium grit sandpaper. Hold your hand under some running water and use the pumice stone or emery board to gently rub the affected area of spray foam off of your skin.
To make it a little easier, add some soap which can help in the process of removing the hardened foam. The benefit of using this method is that you do not use any harmful chemicals or solvents that can damage your skin. You are physically removing the dried foam without having to dissolve it first.
Isopropyl Alcohol
Take a deep bowl and fill it with the alcohol and put your hands into it, soak for around 10 minutes. Now take a clean dry cloth or towel and wipe the foam off. If there is still some foam remaining, repeat this process until it is all removed.
Try not to scratch the foam off as this may cause some damage to your skin.
Vaseline (Petroleum Jelly)
Vaseline is another product that you can use to effectively remove spray foam from your skin. Take some Vaseline and gently rub it into the foam residue on your hands or skin, then take a plastic glove, towel or plastic cling wrap and cover your hands. Wait for about an hour or more, giving the Vaseline time to soften the foam.
Now remove the glove and you should be able to peel the foam off easily. Finish off by cleaning your hands with hot water and soap. If you still find some foam on your hands, use a nail file or other flat object, and scratch the remaining foam completely off. There is no need to moisturize your skin as Vaseline will do that job for you.
Exfoliating Soap
This is one of the easiest methods to break up the foam as exfoliating soap has tiny beads like sand embedded in it, and this helps to remove the foam from your skin. Try to rub the soap into the foam residue using circular movements, which will create friction and cause the dry foam to crumble and break up.
This method may result in some dead skin also being removed, so be careful not to damage your skin too much.
How to get Spray Foam off Your Hands?

Then take some Vaseline and apply it over the entire area where the foam is, and then put your hand into a vinyl or rubber glove and leave it for an hour to let the Vaseline soak into the foam. Then you can remove the glove and wash your hands with some warm soapy water and the dried foam should be gone. Maybe you are not comfortable using these products or you do not have them available in your home. The last option is to simply wait it out. The only thing you need with this option is patience, but it will work.
This method costs you nothing and within five days or so the dried foam wears away on its own and will fall off your skin naturally.
