Q. What's the Best Way to Remove Strong Odors From a Cutting Board?

A. The dishwasher is the best way to clean plastic cutting boards, but often you can't wait two hours to reuse a malodorous board. 

To find the best way to remove odors without a dishwasher, we took four cutting boards and cut a large onion and made garlic paste out of raw minced garlic on each of them. 

Once they were nice and smelly, we used a different odor-removal method on each board before immediately washing it with hot soapy water: 

1. Spraying with a mixture of 1 tablespoon of bleach and 1 gallon of water 

2. Scrubbing with a paste of 1 tablespoon of baking soda and 1 teaspoon of water

3. Spraying with distilled white vinegar

4. Doing nothing more than washing with hot soapy water

After the boards were wiped dry, we sliced apples on each one. 

Tasters were required not only to taste the apples for off-flavors but to sniff the boards as well. 

The results? Only the baking soda paste-treated board was odor-free; the other boards suffered from varying degrees of sulfurous odors and allium flavors. Tasters were nearly unanimous in finding the apples cut on the baking soda board "fine," with "no off-flavors." 

So the next time you stink up your cutting board, scrub it with a baking soda paste and follow up by washing it with hot, soapy water.
