Can You Put a Wooden Cutting Board in the Dishwasher?
Wooden cutting boards are a staple in many kitchens, prized for their durability, natural beauty, and ability to withstand countless chops and slices. However, when it comes to cleaning them, a common question arises: *Can you put a wooden cutting board in the dishwasher?* The short answer is no, but there’s much more to unpack here. In this article, we’ll dive into why dishwashers and wooden cutting boards don’t mix, explore proper care techniques, and provide additional insights to keep your board in top shape for years. Let’s break it down step by step.

Why You Shouldn’t Put a Wooden Cutting Board in the Dishwasher
Wooden cutting boards are made from natural materials, typically hardwoods like maple, walnut, or cherry. While these woods are tough, they’re also porous and sensitive to extreme conditions—like those found in a dishwasher. Here’s why experts universally advise against it:
1. Water Damage and Warping
Dishwashers use hot water and high-pressure jets to clean. When wood is exposed to prolonged moisture and heat, it absorbs water, causing the fibers to swell. As the board dries, it can shrink unevenly, leading to warping or cracking. According to the folks at Serious Eats, “The prolonged exposure to water and heat in a dishwasher will almost certainly warp a wooden cutting board, and potentially cause it to crack as well” [((Serious Eats))]. Once warped, the board loses its flat surface, making it unstable and difficult to use.
2. Drying Cycles Strip Natural Oils
Wood contains natural oils that keep it supple and resistant to wear. The intense heat of a dishwasher’s drying cycle evaporates these oils, leaving the wood brittle and prone to splitting. Epicurious explains, “The heat from the drying cycle can cause the wood to dry out excessively, which leads to cracks and a shorter lifespan for your board” [((Epicurious))]. Over time, this damage is irreversible.
3. Glue Breakdown in Laminated Boards
Many wooden cutting boards are made by gluing strips of wood together. Dishwasher detergents and heat can weaken or dissolve this glue, causing the board to fall apart. The Kitchn warns, “For boards made of glued-together pieces, the dishwasher can break down the adhesive, leading to separation” [((The Kitchn))]. If your board starts shedding pieces, it’s not just a mess—it’s a safety hazard.
4. Bacterial Concerns (Not What You Think)
Some might argue that dishwashers sanitize better than hand-washing, but wood’s porous nature complicates this. While dishwashers kill bacteria with heat, they can also trap water in the wood’s pores, creating a breeding ground for mold or bacteria if not dried properly afterward. Hand-washing with proper drying is a safer bet.

How to Clean a Wooden Cutting Board Properly
Since the dishwasher is off-limits, what’s the best way to clean your wooden cutting board? Here’s a detailed, expert-backed method to keep it hygienic and in great condition:
Step-by-Step Cleaning Process
1. Scrape Off Debris: Use a bench scraper or the back of a knife to remove food bits immediately after use.
2. Wash with Mild Soap: Run the board under warm water and use a soft sponge with a small amount of dish soap. Scrub gently to avoid scratching the surface. Avoid soaking it—keep contact with water brief.
3. Rinse Thoroughly: Ensure no soap residue remains, as it can affect the wood’s taste and finish.
4. Dry Immediately: Pat the board dry with a clean towel, then stand it upright to air-dry completely. This prevents moisture from pooling.
5. Sanitize When Needed: For raw meat or strong odors (like garlic), sprinkle coarse salt over the surface, rub with half a lemon, and rinse. Alternatively, a solution of one part vinegar to four parts water works as a natural sanitizer.
America’s Test Kitchen emphasizes, “Never submerge a wooden cutting board in water—it’s the fastest way to ruin it. Quick washing and thorough drying are key” [((America’s Test Kitchen))].

Beyond Cleaning: Maintaining Your Wooden Cutting Board
Cleaning is just one part of the equation. To extend the life of your board, regular maintenance is essential. Here’s how to keep it looking and performing like new:
1. Oil It Regularly
Wooden cutting boards need conditioning to stay hydrated and crack-free. Food-grade mineral oil is the go-to choice. Apply a thin layer with a cloth, let it soak in overnight, and wipe off excess. Do this monthly or when the wood looks dry. Boos Block, a leading cutting board manufacturer, advises, “Oiling prevents the wood from drying out and splitting, and it enhances its natural beauty” [((John Boos & Co.))].
2. Avoid Cross-Contamination
Use separate boards for raw meat and other foods (like vegetables or bread). This reduces bacterial risk and prevents flavor transfer.
3. Sand Down Scratches
Over time, knife marks can accumulate. Lightly sand the surface with fine-grit sandpaper, then re-oil. This restores smoothness and removes shallow bacteria traps.
4. Store Properly
Keep your board in a dry, ventilated spot—not in a damp drawer or near a sink. Standing it upright helps air circulate.

Exceptions: Are Any Cutting Boards Dishwasher-Safe?
While traditional wooden cutting boards can’t handle the dishwasher, some modern alternatives blur the lines:
- Bamboo Boards: Bamboo is technically a grass, not a wood, and is less porous. However, most experts still recommend hand-washing bamboo boards to avoid warping and glue breakdown.
- Composite or Plastic-Coated Wood: Some boards combine wood with protective layers or resins. Check the manufacturer’s label—*some* are dishwasher-safe, but this is rare.
- Plastic Cutting Boards: If dishwasher convenience is a must, switch to plastic. They’re non-porous and built for the machine.
Always consult the care instructions from the maker. For example, OXO’s wooden board guides explicitly state “hand-wash only” to preserve quality.

The Bigger Picture: Why Wooden Cutting Boards Are Worth the Effort
You might wonder: if wooden boards require so much care, why bother? Research and chefs agree they’re superior in several ways:
- Knife-Friendly: Wood is gentler on blades than plastic or glass, preserving sharpness longer.
- Self-Healing: Small cuts in wood close up naturally, unlike plastic, which harbors deeper grooves.
- Sustainability: Wood is renewable and biodegradable, unlike many plastics.
A study from the University of Wisconsin found that wooden boards may even have natural antibacterial properties, thanks to the way bacteria get trapped and die in the pores [((University of Wisconsin))]. That’s a bonus you won’t get with a dishwasher-safe alternative.

FAQ: Common Questions About Wooden Cutting Boards
Q: Can I soak my wooden cutting board to clean it?
A: No, soaking causes water to penetrate deep into the wood, leading to warping and cracking. Stick to quick washes.
Q: How do I remove stains from my wooden cutting board?
A: Sprinkle baking soda on the stain, scrub with a damp sponge, and rinse. For stubborn marks, use the salt-and-lemon method.
Q: Is it safe to cut raw meat on a wooden cutting board?
A: Yes, as long as you clean and sanitize it properly afterward. Consider dedicating one board just for meat to avoid cross-contamination.
Q: How often should I replace my wooden cutting board?
A: With proper care, a quality board can last decades. Replace it if it’s heavily cracked, warped, or has deep grooves that can’t be sanded out.
Q: Can I use olive oil to condition my cutting board?
A: No, olive oil (or any cooking oil) can go rancid. Use food-grade mineral oil or beeswax-based products designed for wood.
