What is Mold?

What is Mold

Mold is a fungus that thrives in damp environments with excess moisture. The porous, organic nature of wood makes it an ideal food source for mold. To know how to remove mold from wood, it’s essential to understand its root causes:

  • Water leaks, flooding, or condensation collecting on surfaces
  • High indoor humidity and poor air circulation
  • Soaking of wood from storms, plumbing issues, or other water damage
  • Lack of protective sealants and paints on raw wood
  • Wood stored outdoors exposed to rain and moisture

Mold produces microscopic spores that become airborne, allowing it to spread to surrounding areas. Continued moisture exposure causes mold colonies to rapidly grow larger on wood.

To tackle this issue, and if you’re specifically looking into how to kill mold on wood. Or if you are considering methods like removing mold from wood with vinegar, the first step is prevention. And, preventing mold on wood requires controlling humidity, immediately fixing water problems, and properly sealing wood surfaces. Routine cleaning using antimicrobial products also helps avoid mold growth.

What You’ll Need To Remove Mold from Wood

What You'll Need to clean mold

1. Protective Equipment

When you’re looking into how to remove mold from wood, it’s crucial to protect yourself from mold spores and chemicals. You’ll need goggles or safety glasses, an N95 respirator mask, rubber gloves, and old clothes and shoes that cover your skin. Make sure to use a properly fitted N95 mask – avoid touching the front of the mask when wearing and taking it off. Also, open windows or use fans for good airflow.

2. Cleaning Tools

Gather the necessary scrub brushes, sponges, buckets, and rags to clean mold off wood surfaces. Use brass bristle brushes or nylon scrub brushes rated safe for use with chemicals. Have multiple buckets – one for bleach solution, one for vinegar (if you’re exploring how to get rid of mold using natural solutions), and one for rinsing. Stock up on old rags or paper towels. Avoid using your regular sponges and towels.

3. Vacuum

Remember, if you’re embarking on the journey of how to clean mold off wood, a strong vacuum cleaner would be an essential tool. Use the hose and crevice attachments to suck up mold from the porous wood texture before scrubbing. The vacuum helps contain airborne mold spores. Dispose of used vacuum bags carefully by sealing them in plastic before throwing them away.

4. Materials

For killing and removing mold from wood, you’ll need:

  • White distilled vinegar – Helps kill mold and prevent future growth. 
  • Chlorine bleach, oxygen bleach, or peroxide cleaner – Bleach disinfects and whitens moldy wood.
  • Mild detergent – Use for washing and rinsing wood before and after disinfecting.
  • Commercial mold removal products – Useful for serious mold infestations.
  • Plastic tarps or sheets – Cover nearby surfaces to avoid spreading spores.


With all the tools and materials ready and the area contained, you can now scrub away the mold on the wood. If you’re searching for how to remove mold from wood, you’re in the right place.

How to Clean Mold Off Wood

How to clean mold from wood

Follow these methods to fully clean mold off a wood surface:

1. Put on Protective Clothing

Before scrubbing the moldy wood, put on goggles, an N95 mask, gloves, and old clothes, and ensure you have all the necessary gear and supplies ready before beginning to remove mold from the wood.

2. Prepare the Area

Start by isolating the moldy area on the wood. Close doors and use plastic sheeting secured with tape to cover any nearby walls, floors, or furniture. Make sure the room is well-ventilated, and open windows or use fans to circulate fresh air during the process.

3. Mix Cleaning Solutions

Prepare your vinegar, bleach, or other cleaner and detergent solutions according to the product instructions. For bleach, mix 8-ounce bleach with 1-gallon water for optimal mold-killing power. Have a bucket of clean water ready for rinsing the wood after cleaning.

4. Vacuum the Mold From the Wood Surface

Use the vacuum and crevice tool to go over every bit of the moldy wood. Get into corners, cracks, and detailed areas to suck up as much of the mold growth as possible. This helps contain the mold spores before scrubbing. 

5. Wash Sealed or Painted Wood

For sealed, painted, or finished wood, start by washing with a sponge, detergent, and warm water. Rinse off detergent residue. Let the wood dry completely before resealing or painting.

6. Spritz With Distilled White Vinegar

Use undiluted white vinegar in a spray bottle. Liberally spritz the moldy areas and let sit for 1 hour. The vinegar will help kill and loosen mold for easier removal.

7. Use Chlorine Bleach for Tough Mold Stains

For tough stains on raw wood, scrub using a rag or stiff nylon brush dipped in the water bleach solution. Rub gently to avoid damaging the wood. Rinse thoroughly.

8. Rinse Away Residue

Once mold is killed and loosened, use clean water to rinse off any remaining vinegar, bleach, or cleaning product residue. Wipe dry with fresh paper towels.

9. Dry Rapidly

Make sure the cleaned wood dries as quickly as possible. Use fans, heaters, or dehumidifiers. Drying deprives mold of needed moisture.

If you’re keen on understanding how to remove mold from wood, follow these methods to ensure a thorough cleaning.

What to Do if Mold Persists

Check if any discoloration remains after drying. For those seeking ways on how to remove mold from wood, it’s important to repeat the vinegar or bleach application if the mold persists. For stubborn mold that keeps growing back, use a commercial mold removal product. Be sure to follow instructions and precautions. You may need to replace porous wood if the mold damage is severe. Calling a mold remediation pro is advisable for large outbreaks.

Difference Between Mildew and Mold

The Difference Between Mildew and Mold

It’s easy to confuse mildew and mold, and they are often used interchangeably, but they are different types of fungi. Understanding which growth you have will determine the best removal methods.

AppearanceFuzzy, cotton-like texture, 3D coloniesThin, powdery, grayish-black growth
ColorVarious colors, including black, white, green, etc.Mostly grayish-black
TextureGrainy texture that penetrates deeper into porous materialsFlat pattern, easy to wipe away
LocationThrives in any environmentDamp surfaces like tile, drywall, grout, etc.
Removal MethodsMay require more intensive removal methods such as disinfectants, scrubbing, or professional helpBleach can permanently remove and disinfect mildew

Both should be removed quickly to prevent spreading and damage. For those wondering how to remove mold from wood, it’s vital to treat any questionable fungal growth as potentially hazardous mold rather than assuming it is mildew. Contain the area and use an N95 mask when cleaning. Mold can be very damaging to health and property if left unchecked.

What Is Black Mold?

what is black mold

Black mold, also called Stachybotrys chartarum, is an especially toxic form of mold. This dark greenish-black mold grows on very wet materials like drywall, carpets, and wood. It produces harmful mycotoxins that can cause respiratory issues, headaches, and skin irritation when inhaled.

Removing black mold requires extra caution – wear an N95 respirator mask, thick rubber gloves, and goggles. First, contain the moldy area with plastic sheeting to avoid spreading toxic spores. Then, Use a HEPA vacuum before scrubbing to contain and remove the mold. Finally, finish the process by disinfecting all surfaces with an 8-ounce per gallon water bleach mix or commercial antimicrobial. Additionally, consider installing HEPA air filters to remove mold spores during and after remediation.

However, consider hiring a professional mold removal company for large black mold infestations. You need to completely remove and replace damaged drywall, carpet, or other porous materials if needed. Also, be sure to address and fix all moisture problems that allowed the black mold to grow.

How to Prevent Mold Growth on Wood


Here are some tips for those exploring how to remove mold from wood and prevent problematic mold growth on wood surfaces:
