Can You Put Wooden Cutting Board in Dishwasher: A Comprehensive Guide

Wooden cutting boards are a staple in many kitchens due to their natural beauty and durability. However, when it comes to cleaning, there is often confusion about whether it’s safe to put them in the dishwasher. In this article, we’ll dive into the question: Can you put a wooden cutting board in the dishwasher? Let’s explore the do’s and don’ts, the potential risks, and the best practices for cleaning and maintaining your wooden cutting board.

Wooden cutting boards have been a kitchen favorite for generations. They add a rustic touch to food preparation and are gentle on knife blades. However, their maintenance requires careful consideration.

The Benefits of Wooden Cutting Boards

Wooden cutting boards are renowned for their aesthetic appeal and durability. They’re less likely to dull knives and offer a unique natural charm to your kitchen. Their sturdy build allows them to withstand regular chopping without excessive wear and tear.

Understanding Dishwasher’s Impact on Wood

Dishwashers use hot water, strong detergents, and intense heat for drying. These factors can have adverse effects on wooden cutting boards, causing them to crack, warp, and lose their original shape.

Why Putting Wooden Cutting Boards in the Dishwasher is Not Recommended

Wood is porous, and prolonged exposure to water and heat can cause it to swell and shrink, leading to cracks and an uneven surface. The dishwasher’s aggressive cleaning cycle exacerbates these issues.

Potential Risks of Dishwashing Wooden Cutting Boards

  • Warping: High heat and moisture can cause the wood to warp, making it unstable and difficult to use.
  • Splintering: The combination of water and heat may encourage the wood to splinter, posing a risk to both your hands and your food.
  • Bacterial Growth: Dishwashers may not effectively sanitize wood, leaving behind harmful bacteria.
  • Reduced Lifespan: Dishwashing consistently can significantly reduce the lifespan of your wooden cutting board.

Best Practices for Cleaning Wooden Cutting Boards

  1. Hand Wash: Always hand wash your wooden cutting board with mild soap and lukewarm water immediately after use.
  2. Avoid Soaking: Do not soak the board in water or leave it submerged, as this can lead to warping.
  3. Regular Oil Treatment: Apply food-grade mineral oil or beeswax to keep the wood nourished and protected.
  4. Gentle Scrubbing: Use a soft-bristle brush to clean stubborn residue without damaging the wood.

Natural Ways to Disinfect Wooden Cutting Boards

  1. Lemon and Salt: Rub the board with a lemon half and coarse salt to naturally disinfect it.
  2. Vinegar Solution: Wipe the board with a mixture of white vinegar and water to kill bacteria.
  3. Hydrogen Peroxide: A mixture of hydrogen peroxide and water can also be effective against germs.

Maintaining the Longevity of Wooden Cutting Boards

  • Regular Maintenance: Follow a routine of cleaning and oiling to prolong the life of your cutting board.
  • Proper Drying: Ensure the board is thoroughly dried after cleaning to prevent warping.
  • Use Separate Boards: Reserve different boards for various food types to prevent cross-contamination.

Comparing Wooden and Plastic Cutting Boards

While wooden cutting boards require more care, they are generally considered safer and more durable than plastic ones, which can harbor bacteria in knife grooves.

When Dishwashing Might be Okay

In some cases, lower heat dishwasher settings might be safe for wooden cutting boards, but it’s still best to avoid it whenever possible.

Alternative Ways to Clean Wooden Cutting Boards

  • Baking Soda Paste: A paste of baking soda and water can help remove stains and odors.
  • Boiling Water: Pouring boiling water over the board can help disinfect it without the risks of a dishwasher.

Choosing the Right Cutting Board for You

Consider your preferences, cooking habits, and maintenance capabilities when choosing between wooden and other types of cutting boards.


In conclusion, while the dishwasher might be a convenient cleaning option for many kitchen items, it’s best to steer clear of using it for wooden cutting boards. The risks of damage and potential bacterial growth outweigh the convenience. Instead, opt for gentle hand washing, regular oiling, and natural disinfection methods to keep your wooden cutting board in top shape for years to come.
