Stain removal is all about speed and technique. Here's the proven method for tackling crayon from walls effectively.
Before any method, test on a small hidden area like behind a piece of furniture or low on the wall behind a door. Watch for paint pulling, color lifting, or sheen change. The wrong method on flat paint can leave a permanent shiny spot bigger than the original crayon mark.
Apply a small amount of non-gel white toothpaste to a soft cloth. Rub in small circular motions on the crayon mark using light pressure. The mild abrasives in the toothpaste lift the wax without scratching the paint. Wipe with a clean damp cloth when the mark fades.
Magic erasers are highly effective on crayon. Wet, wring out tightly, and rub gently on the marks with light pressure. Magic erasers are mild abrasives and CAN dull flat paint if rubbed too hard, so let the eraser do the work, not your arm.
Make a paste of baking soda and a few drops of water. Apply to remaining crayon marks and scrub gently with a soft cloth or soft-bristle toothbrush in small circles. Best for matte and eggshell paints where you want minimal abrasion.
For crayon that has been on the wall for weeks or has been pressed in hard, spray WD-40 onto a clean cloth (never directly on the wall) and rub the mark. The petroleum solvent breaks down the wax binder. Wipe off the oily residue immediately with dish soap and warm water, then a clean damp cloth, or you will leave a grease ring.
Once the crayon is removed, wipe the wall with mild dish-soap-and-water on a clean cloth to lift any residue (toothpaste, baking soda, or WD-40 oil). Follow with a separate clean damp cloth for a plain-water rinse, then dry with a third clean cloth or microfiber. Skipping the rinse leaves a film that attracts dust and turns dingy in a week.
