Washing Away the Life of Your Cutting Board: The Dangers of Putting a Wooden Board in the Dishwasher

Putting a wooden cutting board in the dishwasher can be detrimental to the board and its longevity. Wooden cutting boards are made from natural materials, and are sensitive to changes in temperature and moisture. The high heat and steam of a dishwasher can cause the wood to warp, crack, or split, as well as dry out the wood fibers, making them brittle and prone to cracking.

Another issue that can occur when putting a wooden cutting board in the dishwasher is that the detergents and sanitizers used in the dishwasher can be harsh on the wood, potentially discoloring or damaging the surface of the board. These chemicals can also cause the wood to absorb odors or flavors, which can be difficult to remove and may affect the taste of future food items.

Additionally, the agitation of the dishwasher can cause the board to become scratched or nicked which can harbor bacteria and can be difficult to clean.

It is recommended to clean wooden cutting boards by hand, using warm water and a mild detergent. Scrub the surface with a brush or sponge, then rinse and dry the board thoroughly. To sanitize the board, you can use a solution of one tablespoon of white vinegar to one gallon of water, or a solution of one teaspoon of chlorine bleach to one gallon of water. Allow the board to air dry or pat dry with a clean towel.

If you want to sanitize your wooden cutting board more effectively, you can use a food-grade mineral oil to seal the surface of the board, which will protect the wood from the harsh effects of water and detergents.

In summary, putting a wooden cutting board in the dishwasher can cause warping, cracking, splitting, and dry out the wood fibers. It can also damage the surface of the board, cause it to absorb odors or flavors, and can make it hard to clean. It's much better to clean wooden cutting board by hand and occasionally sanitize it with a food-grade mineral oil.
