Hand wash with a gentle detergent, do not use steel wool or scouring pads as they will scratch wood; dry immediately with a soft cloth. Do not soak or leave unwashed overnight. Mineral oil can be used to restore richness of the wood color- apply with a soft cloth, let stand one hour and wipe away excess with a gentle detergent, dry immediately. Note— as with all marble, wine or rich colored foods may stain the naturally porous material. Not dishwasher, oven, or microwave safe.
