CARE INSTRUCTIONS: Assuming your block has a finish on it, clean it like you would any wood surface, not allowing water to remain on the block for any length of time. DO NOT put it in a dishwasher! To help preserve your block if used as a cutting surface it would be advisable to periodically reseal ONLY the area in which you have cut. Mineral oil or vegetable oil can be used. If your block becomes necessary to refinish due to usage, we suggest sanding the finish off and applying either an oil finish as mentioned above or resealing with "Good Stuff" Urethane Gel clear protective finish.
