You renovate your child's room to include a floor to ceiling chalkboard wall, only to find that she has used crayons on it. Before you repaint, there are several things you can do to remove the crayon without damaging the coats of chalkboard paint you have applied.
Things You'll Need
Polyester fiber scrub sponge
Tape two layers of absorbent paper towel over the crayoned area. Heat an iron on its lowest setting. Run the iron over the paper towel-covered area until the crayon on the chalkboard melts into the towel to be absorbed by the fibers. Wash gently with degreaser afterward to remove any remaining traces of crayon.
Use a polyester scrub sponge and a little degreaser. Gently rub degreaser over the crayoned area. Wait 10 to 15 minutes for degreaser to eat away the crayon. Wipe with water to rinse.
Apply a 1/4-sized amount of toothpaste to a terry cloth rag. Rub in gentle circles over the crayoned area until it is gone. Be careful not to rub so hard that the finish comes off the chalkboard.
Mix a paste of baking soda and dish liquid. Rub gently until crayon is gone.
Repaint the chalkboard if all these methods fail to remove the crayon.
Use gentle circles when wiping the crayon from the chalkboard to avoid ruining the surface.
