Oiling your butcher’s block is an important part of maintaining it as it keeps it sealed and sanitary, which is very important especially when handling meat. You can use specialized oils that are sold by the butcher’s block brands or simply use walnut oil or food-safe mineral oil. Pour a measure of oil onto the board and spread out evenly across the surface with a dry cloth, leave to soak for 30 minutes. Repeat this process again and then wipe down thoroughly with the cloth. If your board is double-sided repeat this process on the other side a day after the first to allow the oil to soak in. This should be done once a month and will help prolong your board’s lifespan considerably.
