🛑 Why You Shouldn't Use Soap on Moldy Wooden Cutting Boards

As the old saying goes, “Illness enters through the mouth”—so keeping your cutting board clean is essential for protecting your health.

Wooden cutting boards are naturally more eco-friendly and safer than plastic alternatives, but they also absorb moisture easily, especially in humid or rainy weather. Without proper care, this makes them a perfect breeding ground for mold and bacteria.

You might think hot water and dish soap will do the trick, but this can actually dry out the wood, causing it to crack or warp. And worse, soap may not completely eliminate deep-set mold or odors.

Instead, use gentle household ingredients that disinfect, deodorize, and protect the wood—all without damaging it.

🧼 3-Step Cleaning Method with Vinegar, Salt, Toothpaste & Oil

Here’s how to thoroughly clean and restore your wooden cutting board using simple kitchen staples:

🧂 Step 1: Disinfect with White Vinegar and Salt

What you need:

• White vinegar

• Table salt (coarse if available)

How to do it:

1. Pour a generous amount of white vinegar over the surface of the cutting board. This helps loosen any deep-seated grime or mold.

2. Sprinkle salt evenly on top. The salt acts as a gentle abrasive and a natural disinfectant.

3. Let the mixture sit for a few minutes to allow the vinegar to penetrate.

🪥 Step 2: Scrub with Toothpaste and a Toothbrush

What you need:

• A used (clean) toothbrush

• Regular white toothpaste (not gel-based)

How to do it:

1. Apply toothpaste directly onto the board or onto your toothbrush.

2. Use the toothbrush to scrub the surface thoroughly, focusing on knife grooves or any dark moldy spots.

3. The combination of toothpaste and salt provides excellent cleaning power and abrasion, helping to lift stubborn stains and kill bacteria.

This method not only cleans the surface, but also gets into the micro-cuts where mold can hide. After scrubbing for a few minutes, rinse the board with clean water and dry it completely with a clean cloth.

🧴 Step 3: Condition with Cooking Oil to Prevent Mold

What you need:

• Any neutral cooking oil (vegetable, sunflower, or mineral oil for cutting boards)

• Plastic wrap or food-safe film

• Baking soda (optional)

How to do it:

1. Once the board is dry, apply a thin, even layer of oil across the surface.

2. Wrap the board in plastic wrap and let it sit for 4–5 hours. This helps the oil penetrate the wood, keeping it nourished and preventing cracking or mold formation.

3. Afterward, unwrap and check the board. If it feels greasy, don’t use dish soap to wash it off. Instead, sprinkle baking soda over the surface and rub it in to absorb excess oil.

4. Rinse lightly with warm water and dry immediately.

This final step helps keep your cutting board mold-resistant for up to a year, with no harsh chemicals involved.
