Painting carries with it those accidental spills that leave paint on surfaces other than the one you intended. Some surfaces don’t take kindly to paint spills, while others are more forgiving. If you spilt oil-based paint on a rubber surface while you were painting your house, you can remove paint from rubber easily with a few easy-to-find supplies.
Put on protective rubber gloves. It's also a good idea to wear old clothing.
Pour about a cup of paint remover into a plastic spray bottle.
Liberally spray the paint stain on the rubber item with paint remover. Let the remover sit for about 10 minutes, a little longer for thicker paint or larger spills.
Gently wipe the paint away with a clean cloth. Rinse the area with water to remove paint remover residue, and wipe with a clean towel.
To remove water-based paint from rubber, clean the surface with dishwashing soap and water.
Always wear gloves when using chemicals of any kind. Always use paint remover in a well-ventilated space. Always test paint remover on a small patch of the surface first to ensure it won’t damage the surface.
