Wooden cutting boards allow you to cut foods without damaging your actual countertops. When properly cared for, wooden cutting boards maintain their new-looking appearance. When a board becomes stained with grease, however, the unattractive appearance may cause you to avoid using the board -- which will present problems for your countertops. To get rid of the grease and entice you to use the board again, employ a mild cleanser that contains no chemicals, since you are dealing with a surface on which you prepare foods.
Sprinkle a thick covering of baking soda over the grease stain. The baking soda is a natural absorbent that will quickly pull the grease out of the wood. Let the baking soda sit for five minutes.
Rinse a nylon scrub brush under warm water and drizzle the brush with a layer of dish soap.
Scrub the baking soda into the wooden cutting board with the brush. The combination of the baking soda and dish soap will remove any leftover grease residue.
Wipe the cleaning mixture off of the wood with a damp dish cloth.
Dry the cutting board with a dish towel. Repeat this procedure as needed until all grease residue is gone.
