If you have a stubborn crayon mark, sprinkle a little baking soda on a damp sponge and gently rub in a circular motion. If lubricants residue remains, dampen a sponge with a solution of one or two drops of mild dish-washing liquid to one cup water. Squeeze out sponge and gently rub in a circular motion. Rinse sponge; lightly moisten with water to go over area; dry with a clean cloth.
