Can Cutting Boards Go in the Dishwasher? 

Cutting boards are a staple in every kitchen, playing a crucial role in meal preparation. These indispensable tools come in a myriad of materials, including wood, plastic, glass, acrylic, and various composites. 

Despite their differences, they all share a common purpose: to provide a safe and clean surface for chopping, dicing, and slicing. However, a key question often arises when it comes to cleaning—Can cutting boards be safely put in the dishwasher? 

As we navigate through this topic, we will delve into the specifics of different cutting board materials and their compatibility with dishwashers.

Cutting Boards and Dishwasher Suitability

Cutting boards can generally be categorized into five main types, each with different characteristics and dishwasher compatibility.

1. Wooden Cutting Boards

Made from various types of wood, such as maple, walnut, or bamboo, wooden cutting boards are valued for their durability and natural aesthetic. However, they are not dishwasher-safe. The intense heat and water in a dishwasher can cause the wood to warp and crack.

2. Plastic Cutting Boards

Usually made from polypropylene or high-density polyethylene, plastic cutting boards are typically dishwasher-safe. The plastic can withstand the heat of the dishwasher and cleaning is often more thorough, reducing the risk of cross-contamination.

3. Glass Cutting Boards

Although glass cutting boards are dishwasher-safe, they are not recommended for regular use due to their hard surface, which can dull knives quickly.

4. Acrylic Cutting Boards

Similar to glass, acrylic cutting boards are also dishwasher-safe. They are less likely to dull knives but can be susceptible to scratches and cuts over time.

Made from a combination of materials, usually wood fibers and plastic resin, these boards look like wood but have better durability. Most composite cutting boards are dishwasher-safe, but it’s always best to check manufacturer guidelines.

When deciding whether to clean your cutting board in the dishwasher, consider the material of your board above all else. Improper cleaning can lead to a shortened lifespan of your board and potential food safety issues.

Dishwasher-Safe Cutting Boards

  • Plastic Cutting Boards and Dishwasher Suitability

The resilience and durability of plastic cutting boards make them a common choice in many kitchens. 

Made primarily from polypropylene or high-density polyethylene, these boards can withstand intense heat and water exposure in dishwashers. 

This ability allows for a more thorough cleaning process, significantly reducing the risk of cross-contamination and ensuring food safety.

To clean plastic cutting boards using a dishwasher, there are a few recommendations to bear in mind. 

Temperatures should ideally be set between 130 and 150 degrees Fahrenheit. Use dishwasher detergents that do not contain bleach, which can discolor the board. 

The plastic board in the dishwasher should be positioned in the top rack, away from direct heating elements, to prevent warping.

  • Bamboo Cutting Boards and Dishwasher Compatibility

Bamboo cutting boards share a similar aesthetic with wooden boards and have varied compatibility with dishwashers. 

Their construction entails tightly pressing together thin layers of bamboo with adhesives. Due to this, some bamboo boards can tolerate dishwashing, while others might warp or split.

If you choose to clean a bamboo cutting board in a dishwasher, it’s important to recognize the potential risks and follow certain guidelines to ensure its longevity. 

First, always check the manufacturer’s instructions to verify whether your bamboo board is indeed dishwasher-safe. 

If dishwasher cleaning is permissible, use a mild detergent and ensure the dishwasher is on a gentle cycle. 

Lastly, position the board on the top rack and away from the heating element to prevent heat damage.

Cutting Boards That Should Not Go in the Dishwasher

Not all cutting boards are created equal when it comes to dishwasher compatibility. Two types of boards, in particular, require special care: wooden cutting boards and stone cutting boards made of materials such as marble or granite.

  • Wooden Cutting Boards

Wooden cutting boards are not dishwasher-safe due to their porous nature and the sensitivity of wood to heat and moisture. 

High heat and prolonged exposure to water in the dishwasher can cause wooden boards to warp, crack, or even split. 

The intensive cleaning process can also strip away the board’s natural oils, leading to drying and further damage.

The recommended method for cleaning wooden cutting boards is handwashing. Use warm, soapy water to scrub the board after each use gently. 

Rinse thoroughly and towel dry immediately to prevent water absorption. Regular maintenance should include oiling your board with food-grade mineral oil to replenish its natural oils and preserve its longevity.

  • Marble and Granite Cutting Boards

Marble and granite cutting boards also fall into the category of dishwasher-unsafe items. 

The concern here is not so much about the material’s reaction to heat or water—stone can handle both—but rather the potential harm to your dishwasher. 

These boards are heavy and could damage the dishwasher’s rack or even the tub itself.

To clean a marble or granite cutting board, simply wipe it down with a damp cloth after use. If needed, use a gentle cleaner specifically designed for stone surfaces. 

Avoid abrasive cleaners, as they can scratch the surface. Dry the board thoroughly after cleaning to prevent any residual moisture from causing a buildup of bacteria.

  • Glass Cutting Boards

Glass cutting boards are generally considered safe for dishwasher use. Thanks to their non-porous nature, they tend to resist water absorption and are not sensitive to high heat, making them fairly resilient in the dishwasher environment. 

However, potential chipping is a concern. The forceful water jets in the dishwasher and contact with other dishes could chip or crack the glass. 

So, while it’s possible to put a glass cutting board in the dishwasher, it’s prudent to place it carefully and ensure that it’s secure.

  • Acrylic Cutting Boards

Acrylic cutting boards are another popular choice that can safely withstand dishwasher conditions. They are non-porous, resistant to high temperatures, and have strong water jets, making them suitable for regular dishwasher cleaning. 

However, it’s important to keep an eye out for potential warping, especially with prolonged exposure to high heat in the dishwasher. 

As a rule of thumb, acrylic boards are best placed in the top rack of the dishwasher where heat intensity and water force are relatively lower. This precautionary measure can help extend the lifespan of your acrylic cutting board.

Flexible and Composite Cutting Boards

  • Flexible Cutting Boards

Flexible cutting mats are typically made from a type of plastic that can withstand the high temperatures of dishwashers without warping or cracking. 

Their thin, flexible nature allows them to bend without breaking, making them less likely to get damaged by the water force in the dishwasher. 

Due to their size, they are best placed on the top rack of the dishwasher, where they won’t obstruct water flow to other items. 

Keep in mind, though, that sharp edges and high heat can still cause cut marks or slight warping over time, so regular inspection is recommended.

  • Resin Composite Cutting Boards

Resin composite cutting boards are another dishwasher-safe option. These boards are made from a blend of resin and other materials, creating a dense, non-porous surface resistant to high temperatures and harsh detergents typically used in dishwashers. 

However, all cutting boards should be inspected regularly for any signs of wear and tear that could harbor bacteria.

Best Practices for Cleaning Cutting Boards

Regardless of the type of cutting board you own, some general cleaning practices should be adhered to. Firstly, use mild soap and warm water for routine cleaning. 

Avoid abrasive cleaners, as they can create small scratches on the surface, which can harbor bacteria. 

To prevent cross-contamination, special attention should be given to disinfecting your cutting boards, especially after they have been used for cutting raw meats.

Always adhere to the manufacturer’s guidelines for care and maintenance. This includes instructions about the suitability of a particular cutting board for dishwasher cleaning and tips on enhancing the board’s durability. 

For example, wooden cutting boards can benefit from regular treatments with food-safe mineral oil, which helps prevent the wood from cracking and warping.


In conclusion, the compatibility of cutting boards with dishwashers depends largely on the material of the board. 

Acrylic, flexible plastic, and resin composite boards can usually withstand a dishwasher’s high heat and water force, although precautions like using the top rack and regular inspection are advised. 

On the other hand, traditional wooden boards typically require hand washing and special care. 

Regardless of the cutting board you use, following proper cleaning and maintenance practices is crucial. 

This ensures the longevity of your cutting boards and maintains a safe and hygienic environment in your kitchen. 

Remember, a well-maintained cutting board is essential for safe and enjoyable cooking.
