How can I get rid of the onion odor in a wooden cutting board?
Wooden cutting boards are notorious for absorbing smells and stains if not properly cared for. To prevent stains, wash the board after each use and wipe it down with mineral oil to season it. (Resist the temptation to use vegetable oil, even though it’s probably handy; vegetable oil can turn rancid and ruin the board.) To remove odors from a wooden cutting board, rub it with a piece of lemon. Sprinkle the lemon with salt to help remove stains, or rub the board with a paste of baking soda and water.
