Do not use an abrasive material to scrub your bamboo cutting board. Rub the board with your hands or a soft cloth if you need to remove larger pieces of food.
Air drying the board can take a few hours.
If you are dealing with a particularly stubborn stain, apply some baking soda instead. [6] X Research source
Make sure you also scrub the corners and edges of your board.
Your cutting board should still be somewhat wet from the lemon juice when you apply this second layer of salt. Do not dry the lemon juice off of your cutting board.
You can reuse this salt until it is no longer white. Just scrape it into a container and store it.
Only use food grade mineral oil on your bamboo cutting board.
The oil will create a protective barrier that keeps enough moisture in the board to prevent cracking from dryness, but keeps enough water out to prevent warping.
Once the oil has soaked into one side of the board, repeat the process with the other side and the edges.
After the board has soaked, wipe off any excess oil with a clean cloth. Make sure that you set the oil-soaked board on a surface that will not be damaged by oil stains. Putting it on a plate or an air-dry dish rack would be ideal.
You should only need to oil your cutting board 1 or 2 times a month. Some people prefer to treat their cutting boards with oil after every use. This can be time consuming, but it does offer more protection for your cutting board.
