Blank Acacia long board

Hand wash boards in warm, soapy water. Towel dry, and place in a rack to dry. Laying board flat to dry will cause one side to dry faster than the other and may create warping. Apply a quality cutting board oil or cream from time to time when board is completly dry. This will ensure the wood does not dry out and seals the surface. It also enhanced the beauty of the wood.  There are many products to use, including food grade mineral oil, bees wax based creams, and specialty coconut oils.
