How to Clean a Wooden Cutting Board

  1. Wash with hot water and mild dish soap right after use.
  2. Scrub the surface and the grooves with a brush or sponge.
  3. For stains and odors, sprinkle coarse salt, rub with half a lemon, and rinse.
  4. Dry upright with a towel. Never soak the board or put it in the dishwasher.
  5. Once a month, rub on food-grade mineral oil to prevent drying and cracking.

How to Clean a Plastic Cutting Board

Most plastic boards are dishwasher safe, which makes cleaning easy. For hand washing, scrub with hot soapy water. To sanitize, use a solution of about 1 tablespoon of unscented bleach per gallon of water (about 4 liters), let it sit a few minutes, then rinse well.

How to Clean a Bamboo Cutting Board

Treat bamboo like wood: wash by hand, dry quickly, and oil occasionally. It resists moisture a little better than many woods but can still crack if soaked.

Tips to Keep Cutting Boards Safe

  • Use separate boards for raw meat and for vegetables or ready-to-eat food.
  • Wash the board before switching from one food type to another.
  • Replace boards with deep grooves that are hard to clean.

Frequently Asked Questions

Can I use vinegar to sanitize a cutting board?

Diluted white vinegar can help with odors and light cleaning. Hot soapy water is still the most important step.

How often should I oil a wooden cutting board?

Roughly once a month, or whenever the wood looks dry and pale.

Can I use bleach on a wooden board?

It is not recommended. Bleach can dry out and damage wood. Use soap, salt, and lemon instead.
