Silicone caulk (silicone/sealant/silicone sealant) is a sticky, gel-like substance that's either clear or white. It's generally used as a waterproofing sealant around bathtubs, showers and sinks or as a weatherproofing sealant around doors and windows. After finishing a remodeling project, you may find silicone caulk on painted walls. Remove silicone caulk from painted walls before attempting to repaint them, since paint doesn't adhere well to the caulk. The project requires very few tools and materials, although some time and dedication is necessary.
Use a window scraper fitted with a sharp razor blade to remove silicone caulk from a painted wall.
Hold the window scraper at low angle--approximately 20 to 30 degrees--to the caulk and shave away thin layers until there's only one thin layer of caulk remaining on the painted wall.
Mix a solution of powdered oven cleaner with water to a toothpaste-like consistency.
Apply the paste solution to the silicone caulk with a cotton swab and leave it on for approximately three hours. If the caulk doesn't show signs of softening, repeat the application of solution and leave it on for another three hours. Don't get any paste solution on the wall.
Put on cotton gloves and wipe the softened silicone caulk from the painted wall with your fingers.
Touch up the paint on the wall if necessary.
Things You Will Need
Window scraper with razor blade
Powdered oven cleaner
Work slowly and patiently while applying light pressure--for better control--when shaving away the silicone caulk.
Don't use a razor blade alone to shave away the caulk (silicone/sealant/silicone sealant); a utility knife or window scraper loaded with a razor blade provides greater control while shaving the caulk.
