For best results, use cutting board oil first, then butcher block conditioner. Coat each of the wooden bowls and utensils once, leave for at least 20 minutes, then wipe off the excess. New or raw wood surfaces, such as chopping boards and butcher blocks, should be greased with chopping oil. To properly oil the new wood surface, apply at least 2 coatings and soak each coating for at least 1 hour. For thick surfaces, coat 3-4 times. An additional coating allows the oil to completely seep into the wood. After cutting board oil, keep the wood with Butcher block conditioner. The conditioner protects the wood by retaining mineral oil and blocking moisture.
