The cutting board is the workhorse of the kitchen, and this important item needs to be cleaned and maintained properly to ensure bacteria that causes illness doesn’t linger on its surface after use. And, since many boards are used for serving as well as for prep, you’ll want to keep them looking guest-worthy.
Cutting boards come in a variety of materials, from wood and bamboo to plastic and composite materials. There are also glass and natural stone boards that are used more for serving than for food preparation that also need to be properly cared for to ensure you do not sicken your household. Ahead, with the help of experts, we’ve broken down everything you need to know about washing, sanitizing, drying and storing cutting boards.
How to clean wood and bamboo cutting boards
“Wood cutting boards require a little bit more care than other boards,” says Meredith Abbott, a culinary director for Sur La Table, “however, if they are properly cared for they can last decades.”
Wood cutting boards should be washed by hand after each use; never put a wood cutting board in the dishwasher. “For wood boards,” Abbott says, including butcher block counters, “scrub with hot, soapy water and a soft textured scrubber.”

To ensure the board is thoroughly cleaned, after washing the board with hot soapy water, Abbott says to “scrape with a metal bench scraper, rinse with hot water, and dry.”
It’s best to dry a cutting board immediately after washing, rather than allowing it to air dry, as moist conditions can lead to bacterial growth that can cause foodborne illnesses. After drying, Abbott says, “rub butcher block oil into the wood.”
When purchasing a new cutting board, ease of care is a factor to consider — and bamboo boards require less care than their wood counterparts. “Bamboo boards can be scrubbed with hot soapy water to clean,” Abbott says. However, like wood cutting boards, bamboo boards should be dried immediately after washing to prevent bacterial growth.
“One of the greatest benefits of a plastic cutting board,” says Ilana Rosen, a senior product manager at OXO, “is that they are dishwasher safe. Sticking your cutting board in the dishwasher is the best way to give your cutting board an everyday cleaning.”
“If the board needs to be fully sanitized once in a while,” Rosen says, “especially after touching raw meat or poultry, create a solution with a ratio of 1 tablespoon of bleach to 1 gallon of water and soak for a few minutes before thoroughly washing it clean.”

How to clean natural stone and glass cutting boards
“Stone and glass cause too much wear and tear on your knives, these are best used as cheese or charcuterie boards or serving pieces,” Abbott says. “I would suggest replacing these with bamboo, wood or plastic cutting boards.”
Dishwasher detergent that contains acidic ingredients, like lemon, is safe for use on glass but not on natural stones like marble or slate.
Glass cutting and serving boards are best cleaned in the dishwasher, providing the board is dishwasher-safe. Glass boards can also be washed by hand with hot, soapy water, and sanitized with bleach using the same method to sanitize plastic boards.
Marble, slate and other natural stone boards should be washed by hand with hot water, dish detergent and a non-abrasive sponge; do not use steel wool or other heavy duty scouring sponges or brushes on natural stone. Natural stone boards should not be cleaned in the dishwasher, as the heat and temperature fluctuations can cause the stone to crack. Avoid exposing any kind of natural stone to acids, including vinegar and lemon juice, as they can cause pitting.
Tips for removing stains and odors from cutting boards
The best thing you can do to keep your cutting boards from taking on a foul odor is to keep them in tip-top shape. “A well-maintained cutting board should release smells fairly easily,” Abbott says, but when it comes to stains, things get a bit trickier. “Some foods just stain, like beets, I would suggest washing immediately after prepping those highly-staining foods,” she says.
Rosen echoes that hard truth, “It’s not always possible to completely remove stains from your cutting board,” she says, “but I like to think of those stains as evidence of the effort I put into preparing meals for my loved ones.”
When it comes to stubborn odors, Rosen recommends using items that are probably already in your kitchen: “An easy way to remove stains and odor from your cutting board is to use the cut side of half a lemon to scrub the cutting board with salt. This can help to lift the stains and leave your cutting boards smelling fresh.” For more ways to deal with smells, check out our guide to the 17 best odor eliminators.

Regardless of what material they’re made of, cutting boards have a lifespan, and they do need to be replaced every few years.
“Replace boards of any material when they develop deep grooves that are hard to clean,” Abbott says, adding, “A sign that your wood or bamboo board needs to be replaced is if it’s warped or has cracks in the grain.” Plastic or composite boards should be replaced every few years, while a wood cutting board with deep scratches but no cracking can be refinished by sanding, cleaning and oiling it. “But,” Abbott says, “trust your gut, if you think your board needs to be replaced, replace it.”
