Pour a small amount of Pine-Sol on a damp washcloth. Scrub the Sharpie mark for about one minute. You may need to add more Pine-Sol and scrub a little longer if there is a large amount of marker on the wall.
Take a sponge and apply a small amount of nail polish remover without acetone. Rub the nail polish remover over the marker area until it’s removed. If the Pine-Sol did not effectively remove the marker, try the nail polish remover without acetone. The nail polish remover will not damage the paint.
Squeeze a small amount of toothpaste on the Sharpie mark and scrub with a clean cloth if other methods prove unsuccessful. Wipe the area clean with a damp clean cloth.
Clean the surface again with plain soap and water to remove any chemicals. Let the area dry. For safety purposes, it’s ideal to remove any chemicals left on the wall.
