Crayon marks on a concrete outdoor table can be stubborn, but with the right techniques, they can be removed easily. Here are some effective methods:

1. Dish Soap and Warm Water: Mix a few drops of dish soap with warm water. Scrub the stained area with a soft brush or sponge. Rinse thoroughly and repeat if necessary.

2. Baking Soda Paste: Create a paste using baking soda and water. Apply it to the crayon marks, let it sit for 10 minutes, then scrub gently with a brush. Rinse with water.

3. WD-40 or Goo Gone: Spray a small amount of WD-40 or Goo Gone on the stain. Let it sit for a few minutes, then wipe away with a cloth. Wash the area with soapy water afterward.

4. Magic Eraser: Use a magic eraser sponge to gently rub the crayon marks. This works well for lighter stains without damaging the concrete.

5. Pressure Washer: For deep-set stains, a pressure washer on a low setting can help blast away crayon marks. Be cautious to avoid damaging the concrete surface.

Prevent future stains by applying a concrete sealer to your outdoor table. Regular cleaning will also keep it looking fresh and stain-free.

By following these steps, your concrete outdoor table will be free of crayon marks and ready for use again!
