How to Remove Mold from a Cutting Board

Wooden cutting boards are a staple in many kitchens, prized for their durability and natural appeal, plus they’re a sustainable, plastic-free choice. But if you’ve ever left your board damp or stored it improperly, you may have encountered an unwelcome guest: mold. Don’t worry—your cutting board can be saved! With a few simple steps and household ingredients, you can restore your board to its former glory. Here’s how to remove mold from a cutting board effectively.

How to Remove Mold from a Cutting Board

Step 1: Clean the Surface

Start by rinsing the cutting board under warm water to remove any loose debris or surface mold. Use a gentle dish soap and a scrub brush to give it a quick clean. Dry it thoroughly with a clean towel before proceeding to the next step.

Step 2: Use a Vinegar-Soaked Rag

Vinegar is a natural mold fighter, and it’s perfect for cleaning wood without harsh chemicals. Soak a clean rag in white vinegar and place it over the moldy area of the cutting board. Let it sit for about an hour. The acidity of the vinegar helps break down the mold, making it easier to remove.

Step 3: Scrub with Salt and Lemon

After the vinegar treatment, sprinkle coarse salt (like kosher or sea salt) over the affected area. Cut a lemon in half and use it to scrub the salt into the cutting board. The abrasive salt works to lift any remaining mold, while the lemon’s natural acidity acts as an additional cleaning agent. Plus, it leaves your board smelling fresh!

Step 4: Sand if Necessary

If stubborn mold spots remain, it’s time to break out the sandpaper. Use fine-grit sandpaper to gently sand away the mold. Focus on the affected area, but be sure to blend the edges so the board maintains a smooth surface. Wash the board again to ensure you remove any dust.

Step 5: Condition Your Board

Now that your cutting board is mold-free, it’s important to give it some TLC. Conditioning your board helps protect the wood, keeping it from drying out or absorbing too much moisture in the future. I love using my DIY wood conditioner made with beeswax and coconut oil—it’s all-natural, smells amazing, and works wonders to keep your board looking its best. Simply rub a small amount onto the surface, let it soak in for 10-15 minutes, and then buff it with a clean cloth.

Resourceful Living: Care for What You Have

Choosing to care for your cutting board rather than replacing it is a small but meaningful act of resourceful living. When we take the time to maintain and repair the items we own, we reduce waste, save money, and honor the resources that went into creating them. A well-loved and well-maintained cutting board can last for years, standing the test of time and countless recipes.

Resourceful living isn’t just about frugality—it’s about making thoughtful choices to live sustainably and mindfully. By learning how to remove mold from a cutting board, you’re not only saving your kitchen staple but also embracing a lifestyle that values care over consumption.

Tips to Prevent Mold in the Future

• Dry Thoroughly: Always dry your cutting board completely after washing.
• Store Properly: Store your board upright or in a well-ventilated space to prevent trapped moisture.
• Regular Conditioning: Keep your board conditioned with a natural wood conditioner to protect the surface and repel water. (I always recondition my wood cutting boards and spoons are the beginning of every month!)

By following these steps, you can confidently tackle mold and keep your cutting board in tip-top shape. Whether you’re a seasoned cook or a casual baker, knowing how to remove mold from a cutting board is a skill every kitchen needs.
