Great Stuff™ comes in cans with a straw applicator or the new patented Smart Dispenser™.  Cans are in 12, 16, and 20 oz sizes.

1. Unscrew used Great Stuff Pro™ from dispensing gun.
2. Clean the gun basket and tip by generously spraying and removing uncured foam with Great Stuff™ Foam Cleaner.
3. Invert the can and install the cleaner onto the dispensing gun.
4. Press the trigger to flush the foam into waste receptable until only the cleaner is visible.
5. Allow gun to sit for several minutes and repeat with a second flush.
6. Remove the can from the dispensing gun and spray into waste receptacle without the can until the gun is completely empty.

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.

Depending on where you live, you can buy Great Stuff™ products from local retail and hardware stores near you. Visit the Where to Buy page to find a retailer near you.

There is no solvent that will remove cured insulating foam. If the foam has not cured yet, use Great Stuff Pro™ Foam Cleaner or fingernail polish remover (with acetone) to quickly remove the uncured foam. Test a small area of the substrate first as the chemicals in the nail polish remover and gun cleaner may not be compatible with the substrate being cleaned. For cured foam, remove as much as possible with a dull scraper or a hacksaw blade and then try scrubbing the remaining film with a non-abrasive cleaner. If that does not work, gradually move up to more aggressive means including sanding, sandblasting and repainting.
