5 Tips on How to Remove Mold on Wood

Remove Mold on Wood

Mold growth on wood is a problem many homeowners face. It can appear on wooden furniture, floors, window frames, or even in the structure of your home. Mold doesn’t just look bad—it can cause musty odors, trigger allergies, and weaken the integrity of wood over time. The longer it’s left untreated, the harder it becomes to remove.

Fortunately, there are effective ways to remove mold from wood and steps you can take to stop it from coming back. Below are five essential tips on how to safely and properly remove mold from wood surfaces. And if the problem is more serious than you can handle, you can always count on PuroClean of Northeast Tacoma for professional mold remediation services.

1. Identify the Mold and Assess the Damage

Before you start cleaning, you need to figure out how severe the mold problem is. Mold on wood usually looks like dark green, black, or even white patches. You may also notice a damp, earthy smell.

• Surface mold: If it’s just on the top layer of the wood, you can often remove it with household cleaning solutions.
• Embedded mold: When the mold penetrates deep into the wood, it’s much tougher to clean. In these cases, you may need stronger treatments—or help from a professional team.

As a general rule, if the mold covers more than 10 square feet or keeps coming back after cleaning, that’s a clear sign to call in experts.

2. Protect Yourself Before Cleaning Mold

Mold isn’t just a nuisance—it can affect your health. Spores become airborne during cleaning and may cause skin irritation, coughing, or even breathing problems. That’s why safety precautions are a must.

Here’s what you’ll need before you begin:

• Gloves (rubber or disposable) to protect your hands
• Goggles to keep spores out of your eyes
• A face mask or N95 respirator to protect your lungs
• Old clothing that you can wash immediately afterward

Ventilation is also important. Open windows and doors, and if you can, set up a fan to help direct spores outside.

3. Start with Gentle Cleaning Solutions

If the mold is minor, start with simple solutions that are less harsh on wood:

• Soap and Water: Mix mild dish soap with warm water and gently scrub the surface using a sponge or soft-bristled brush.
• White Vinegar: Spray undiluted vinegar directly onto the mold. Let it sit for at least an hour before wiping it off. Vinegar is a natural antifungal and helps prevent regrowth.
• Baking Soda: Mix one tablespoon with a cup of water, spray onto the area, scrub, and wipe clean. Baking soda also neutralizes odors.

Be careful not to use too much water, since excess moisture can seep into the wood and actually encourage more mold growth.

4. Use Stronger Cleaning Agents for Stubborn Mold

When natural solutions don’t work, you may need to use stronger cleaners:

• Borax: Mix one cup with a gallon of water, scrub the moldy area, and leave it to dry. Borax is effective because it kills mold and also helps prevent it from coming back.
• Hydrogen Peroxide (3%): Spray directly on the mold, wait 10–15 minutes, then scrub and wipe clean.
• Bleach: This should only be used as a last resort, since it can damage and discolor wood. If you do use bleach, dilute one cup in a gallon of water.

Always test a small, hidden spot before applying any cleaner to the entire area to avoid damaging your wood.

5. Prevent Mold from Coming Back

Once you’ve removed the mold, the most important step is to stop it from returning. Mold thrives in damp, poorly ventilated areas, so reducing moisture is key.

Here are some preventive measures you can take:

• Keep indoor humidity below 60% by using a dehumidifier or air conditioner.
• Repair leaks from pipes, roofs, or windows right away.
• Install or use exhaust fans in kitchens, bathrooms, and basements.
• Avoid pushing wooden furniture directly against walls that may collect condensation.
• Regularly inspect your home, especially basements, crawl spaces, and attics.

A dry, well-ventilated home makes it much harder for mold to grow again.
