1. Spread a layer of salt on top of your cutting board.
2. Use half a lemon to rub the salt around the board. Squeeze the lemon to allow the juice to coat the board.
3. After a few minutes of scrubbing, rinse thoroughly with water.
4. Let the board air dry.
5. Once the board is completely dry, rub coconut oil (or mineral oil) all over the surface. Let sit overnight.
