Before starting work, use a mask and dust goggles. Particles of rubbed foam can get into the eyes and nose.
The easiest way is to remove spray foam while it's still moist. Use a plastic scraper to avoid surface scratching. Remove a maximum of foam; avoid spreading it on the surface. Moisten a sponge with a dissolvent. The optimal option is acetone or even nail polish remover. Remember, they are not appropriate for delicate materials and plastic.
