It is important to remember that most, if not all, wooden cutting boards are made with water-resistant glue, not water-proof glue. After every use, wash your cutting board with hot water and a sponge, with soap or a liquid dish detergent, but not with a product intended for the dishwasher. Place the cutting board on edge in a dish drainer or hand dry with a dish towel. Never leave a wooden cutting board soaking unattended in a sink or dish pan. Never put a wooden cutting board in a dishwasher. If you do, the surface of the board will become rough and the glue joints WILL eventually fail.
If any of your wooden products begin to look dry or dull, apply a generous coat of a food-safe mineral oil finish. Heat the oil up a bit first if possible, then wait a few hours (or even overnight) and wipe off every trace with a towel. The idea is to protect the wood, but not allow the oil to build up. Don’t use vegetable oil or olive oil; they get sticky and go rancid after a while. There is no “rule of thumb” on how often you should refresh the finish, but certainly at least 2-3 times each year. You can also sand lightly with a fine grit sandpaper to refresh the "fuzzy" finish at any time.
All of the wood products have already been finished with a mineral oil and beeswax mixture that we make here, but we can send you more of this if you would like.
