Video of the Day

Fill your sink with an equal combination of hot water and white vinegar, using enough liquid to submerge the cutting board.

Place your wooden cutting board in the vinegar and water mixture, and let it sit for one minute. This allows the liquid to absorb into the board.

Place the cutting board on a large microwave-safe plate and put both in the microwave.

Turn on the microwave for one minute at high heat. The steam from the water and vinegar will naturally deep-clean and disinfect the wood, while soaking it in the solution beforehand prevents heat damage.

Allow the cutting board to cool for two to three minutes and remove it from the microwave.
