Q.How do I get Great Stuff™ foam off of my skin?
A. If the foam has not cured or hardened, use fingernail polish remover (with acetone); a polyglycol-based skin cleanser or corn oil may be effective. Then wash with soap and plenty of water. If the foam has hardened, there is no solvent that will remove it. It will not harm your skin and will wear off over time. To remove cured foam from skin, use a pumice stone (available at most drug stores) and warm, soapy water. Then apply petroleum jelly.
