If you have children, chances are at one time or another your little darling will play Picasso (or one of his/her friends will) on one of your nice light colored walls. Here are several simple ways to remove crayon marks from walls and other surfaces.
Baking Soda: This one is by far the best on the list, it works remarkably well with very little effort. Wet a clean washcloth or cotton cloth and wring it out, dip the cloth in baking soda and rub gently to remove the crayon marks from painted walls. Wipe with a clean cloth to remove any leftover residue.
Alcohol: Rubbing alcohol can mixed with water at a 1/3 ratio (1 pt alcohol/3 pts water), apply with a soft clean cloth to remove crayon marks from carpeting.
WD40: Did the kids use your wall as if it was a big coloring book? Spray some WD-40 onto the marks and wipe with a clean rag. WD-40 will not damage the paint or most wallpaper (test fabric or other fancy wall coverings first). It will also remove marker and crayon marks from furniture and appliances.
Toothpaste: Roll up your sleeves and grab a tube of non-gel toothpaste and a rag or—better yet—a scrub brush. Squirt the toothpaste on the wall and start scrubbing. The fine abrasive in the toothpaste will rub away the crayon every time. Rinse the wall with water.
Mayonaise: Here’s a simple way to remove crayon from a painted wall that requires hardly any elbow grease: Simply rub some mayonnaise on the crayon marks and let it soak in for several minutes. Then wipe the surface clean with a damp cloth.
Pencil Eraser: Try “erasing” the crayon marks to get the wall back to a clean slate.
Steel Wool: Your toddler just created a work of crayon art on paper. Unfortunately, it’s on yourwallpaper. Use a bit of steel wool soap pad to just skim the surface, making strokes in one direction instead of scrubbing in a circle, and your wall will be a fresh “canvas” in no time.
Soapy Water: Crayon marks on silverware or stainless steel surfaces will wash away easily with simple soap and water.
