Removing Crayon Marks from Walls
To remove crayon marks from walls with WD-40, spray the affected area with WD-40 and let it sit for a few minutes to penetrate the crayon wax. Using a clean cloth or sponge, gently scrub the crayon marks in circular motions. The WD-40 will help break down the crayon marks, making them easier to wipe away. Finally, wipe the wall clean with a damp cloth to remove any residue.
