Children love crayons and eventually they seem to find their artistic ways on the walls of your house. Instead of panicking, relax and use a common household product to clean off the scribbles.
You know that citrus scented stuff, Goo Gone? Use a washcloth and scrub the spot with the solution. After you have magically erased the marks from the wall, use soap and water to wipe it clean. Once it dries, your wall should be as good as new.
Of course if it's a work of art and you have a masterpiece on your hands, you might want to turn that wall into a free for all and let 'em at it!
Has this Goo Gone trick ever worked for you?
