There are several ways to remove crayon from walls without damaging the paint. Here are some methods:

1. All-purpose cleaner: Spray the stained area with all-purpose cleaner and wipe with paper towels. If the stain persists, dampen a sponge with warm water and liquid dish soap to work on the stain.

2. Distilled white vinegar: Dip an old toothbrush into a cup of distilled white vinegar and use it to gently scrub the crayon off the wall. Then take a microfiber rag and wipe the wall clean with some warm water. If you dont like the smell of vinegar, you can use Dawn dish soap and water to wash the wall after the crayon is gone.

3. Baking soda: Wet a sponge, dip it in baking soda, and use some elbow grease to scrub the crayon off the wall. Wipe clean with a damp towel.

4. Mayonnaise: Slather mayonnaise over the crayon marking and let it soak for a few minutes. Then wipe the mayo off with a damp cloth. If the crayon doesnt come off, try using a pencil eraser or baking soda.

5. Pencil eraser: Use a pencil eraser to erase the crayon markings. This method may not work for all types of paint.

6. Glass cleaner: Spray glass cleaner on the crayon markings and wipe with a clean cloth.

Its important to test any cleaning method on a small, inconspicuous area of the wall first to make sure it doesnt damage the paint.
