Butcher block conditioner is a combination of pure USP-grade mineral oil, beeswax and carnauba wax. It is ideal for conditioning and maintaining all wooden butcher blocks, cutting boards, wooden bowls and utensils. The penetrating quality of food-grade mineral oil along with the water-resistant traits of beeswax and carnauba wax helps to rejuvenate the wood and prevent drying. Safe for all wood surfaces that come in contact with food, including butcher block countertops, cutting boards, wooden bowls and utensils. Contains food-grade mineral oil stabilized with Vitamin E. Mineral oil will never go rancid like some plant-based oils.
