How to Remove Mold from Wood: Get Rid of Fungus & Mold Fast

What Does Mold on Wood Look Like?

Spotted something fuzzy on your wood floors or furniture? You need to act fast. Mold spreads quickly and can damage both your health and your home.

Before you can remove mold from wood, you need to know what you're dealing with.

Common Types of Mold on Wood

Black Mold (Stachybotrys chartarum)

• Appears as black spots or streaks
• Loves damp, humid spaces like basements
• The most dangerous type—take it seriously

Aspergillus

• Shows up as green or yellow patches
• Common in poorly ventilated areas
• Can trigger allergies and respiratory issues

Penicillium

• Blue or green with a fuzzy texture
• Often found on water-damaged wood
• Spreads rapidly if left untreated

How to Tell If It's Mold (Not Just a Stain)

Not sure if what you're seeing is mold? Here's how to tell:

Sign	What to Look For
Color	Irregular patches that don't match the wood grain
Smell	A musty, earthy odor
Texture	Fuzzy, slimy, or powdery surface

Quick Test: Shine a flashlight at an angle across the surface. Mold will cast tiny shadows due to its raised texture. Wood stains won't.

Don't Forget Hidden Mold

Mold doesn't always stay visible. It can hide behind walls where you can't see it. If you smell mold but can't find it, check our guide on how to tell if there's mold behind walls.

Best Cleaning Solutions to Remove Mold from Wood

• Safe for finished and unfinished wood

Dish Soap + Water

• Mix: 1 teaspoon soap per cup of warm water
• Best for: Surface mold on finished wood

For Stubborn Mold

Hydrogen Peroxide (3%)

How to Get Mold Out of Wood: Step-by-Step

Follow these steps to remove mold from wood floors, furniture, or trim.

Step 1: Prepare the Area

• Move furniture and rugs away
• Open windows and doors for ventilation
• Put on your protective gear

Step 2: Vacuum Loose Spores

Use a vacuum with a HEPA filter. This traps tiny mold spores instead of blowing them around. Go slowly over the affected area.

Step 3: Apply Your Cleaning Solution

• Spray vinegar or your chosen solution onto the mold
• Don't oversaturate the wood
• Let it sit for 5-10 minutes

Step 4: Scrub Gently

Use a soft-bristled brush. Scrub in the direction of the wood grain. Apply light pressure—you want to remove mold, not damage the wood.

Step 5: Wipe Clean

Use a damp cloth to wipe away the residue. Rinse your cloth frequently.

Step 6: Dry Completely

This step is crucial. Moisture left behind invites mold back. Use fans, open windows, or a dehumidifier. The wood should be bone dry within 24-48 hours.

How to Prevent Mold from Coming Back

You've removed the mold. Now keep it gone. Prevention is simpler than cleanup.

Control Your Humidity

Mold needs moisture. Keep indoor humidity between 30-50% and mold can't grow.

Quick wins:

• Run a dehumidifier in basements and bathrooms
• Use exhaust fans when cooking or showering
• Keep AC running during humid months
• Don't overwater houseplants

Fix Leaks Immediately

Water leaks are the #1 cause of mold. A small drip today becomes a big mold problem tomorrow.

Check these spots monthly:

• Under sinks
• Around toilets and tubs
• Near windows and doors
• In the basement and attic
• Around your water heater

Roof leaks? Even minor roof damage lets moisture in. Consider roof tarping as a temporary fix until repairs are done.

Improve Air Flow

Stagnant air traps moisture. Keep air moving:

• Open closet doors periodically
• Leave space between furniture and walls
• Run ceiling fans
• Don't block air vents

When to Call a Professional

Sometimes DIY isn't enough. Call the pros when:

Size Matters

If mold covers more than 10 square feet (roughly a 3x3 foot area), you need professional help. Large colonies go deep into wood. Surface cleaning won't cut it.

It Keeps Coming Back

Cleaned it twice and it's back again? There's a hidden moisture source. Professionals find and fix the root cause.

Black Mold

Suspect black mold (Stachybotrys)? Don't risk it. This type releases dangerous toxins. Pros have the equipment to handle it safely.
