All cutting boards, and other food surfaces, should be kept dry when not in use. Keep moisture of any type from standing on the cutting board for long periods of time.
Cutting boards should be cleaned and sanitized frequently using one of the following methods.
The cutting board is one of the hardest-working wood surfaces in your home. To keep it functional and looking beautiful, it should be re-seasoned at least once a month. If it is used everyday, once a week would be best. There are many cutting board and butcher block oils available. It is best to choose one that is made of mineral oil with some beeswax to help seal the grain and keep water out. An oil finish can help to prevent the wood from cracking over time.
Fortunately, re-seasoning your cutting board can be an easy process. Simply wipe the board down with the food-grade mineral oil-based finish, let it sit for a few minutes, then wipe off the excess. Do not use other oils such as canola or olive because they can become rancid over time.
