Keeping Flipping Oil pure allows a deeper penetration into the surface of the wood allowing longer times between applications. Flipping Butter helps seal in the oil and maintain a cleaner surface. Wood absorbs moisture around it unless there is no where the moisture has to go. Deep down wood doesn’t allow air so it naturally helps to prevent bacteria growth. Flipping Oil has its own antimicrobial properties to help keep your wood surfaces clean and ready for contact with food.
