What is mold?

Mold, also known as mould, is a structure that can be formed by certain types of fungi. It appears as a colored, dust-like substance due to the spores that contain fungal secondary metabolites.

How to Remove Mold

Mold can grow on any surface that has moisture, and wood is no exception. Mold growth on wood can not only damage the appearance of the wood but also compromise its structural integrity.

Therefore, it is crucial to remove and clean mold from wood as soon as possible. In this blog post, we will provide a step-by-step guide on how to remove mold and clean from wood effectively.

Step 1: Safety Precautions

Before starting the mold removal process, it is essential to take necessary safety precautions. Mold spores can cause health problems, including allergies, respiratory problems, and even infections. Wear protective gear, including gloves, goggles, and a face mask, to prevent exposure to mold spores.

Step 2: Identify the Mold

Mold can have various colors, including black, green, white, and brown. Some molds may not be visible, and you may only notice a musty odor or discoloration on the wood surface. It is essential to identify the type of mold to choose the appropriate cleaning method. If you are unsure about the mold type, you can consult a professional for advice.

Step 3: Remove the Mold from Wood

The first step in removing mold from wood is to dry the affected area. Use a dehumidifier, fans, or open windows to improve air circulation and reduce moisture. Next, use a stiff brush to scrub the mold off the wood surface. You can also use a scraper or a putty knife to remove stubborn mold.

Be careful not to damage the wood surface while scrubbing or scraping. Dispose of the moldy materials in a sealed bag and clean the area thoroughly.

Step 4: Clean the Wood Surface

After removing the mold, it is essential to clean the wood surface thoroughly to prevent mold regrowth. Use a solution of warm water and detergent to clean the wood. You can also use a solution of one part vinegar and one part water or a commercial mold cleaner.

Apply the solution to the wood surface using a scrub brush or sponge. Let the solution sit for about 15 minutes, then rinse the surface with clean water and dry thoroughly.

Step 5: Sand the Wood Surface

If the mold has caused stains or discoloration on the wood surface, you can sand the wood to remove the stains. Use a fine-grit sandpaper and sand the affected area in the direction of the wood grain. Sand the wood until the stains are no longer visible.

Step 6: Apply a Mold Inhibitor

After cleaning and sanding the wood surface, apply a mold inhibitor to prevent future mold growth. You can use a commercial mold inhibitor or a natural solution such as tea tree oil or grapefruit seed extract. Apply the mold inhibitor according to the manufacturer’s instructions and allow it to dry completely.

Step 7: Prevent Future Mold Growth

Preventing future mold growth is essential to ensure that the mold does not return. Keep the wood surface dry and well-ventilated. Fix any leaks or moisture problems in the area. Regularly clean and inspect the wood surface for any signs of mold growth.

Tips For Removing Mold From Hard-To-Reach Areas

Mold can be a stubborn and persistent problem, particularly in hard-to-reach areas. However, with the right approach, you can effectively remove mold from even the most inaccessible corners and crevices of your home. Here are some tips for removing mold from hard-to-reach areas:

1. Use a Mold Remover Spray

There are many mold remover sprays available on the market that are specifically designed for hard-to-reach areas. These sprays can penetrate deep into crevices and cracks, killing mold spores and preventing regrowth. Be sure to follow the instructions on the label carefully and wear protective gloves and a mask while using these sprays.

2. Try a Steam Cleaner

If you have a steam cleaner, it can be an effective tool for removing mold from hard-to-reach areas. The high temperature of the steam can kill mold spores and loosen stubborn mold growth, making it easier to clean. Be sure to direct the steam directly at the mold growth and hold it in place for several seconds to ensure thorough cleaning.

3. Use a Brush or Scrubber

For mold growth that is particularly stubborn, you may need to use a brush or scrubber to physically remove it. Choose a stiff-bristled brush or scrubber that is appropriate for the surface you are cleaning and scrub the affected area vigorously to remove the mold. Be sure to dispose of any moldy materials carefully to prevent the spread of spores.

4. Use a Vacuum Cleaner

If you have a vacuum cleaner with a HEPA filter, it can be an effective tool for removing mold from hard-to-reach areas. Use the crevice tool attachment to reach into crevices and corners and vacuum up any visible mold growth. Be sure to empty the vacuum canister carefully and dispose of any moldy materials in a sealed bag.

FAQ About Removing Mold

Can you permanently remove mold from wood?

In short, you can kill mold on wood, but it may not be possible to permanently remove it if the wood is extensively damaged or if the mold has penetrated deep into the wood fibers. It is possible to treat small areas of mold on wood using a scrub brush, dish soap, and vinegar. However, for large areas, it may be necessary to call in a professional mold remediation company. If the wood is moldy and rotting, it will likely need to be replaced.

What causes mold on wood?

Mold on wood is typically caused by excess moisture and humidity. When wood is exposed to a damp or humid environment, it can provide an ideal breeding ground for mold spores to grow and thrive. This can be due to a variety of factors, including water leaks, flooding, high humidity levels, or poor ventilation.

Is mold on wood harmful?

Yes, mold on wood can be harmful. In addition to being unsightly, it can pose health risks to individuals with allergies or respiratory issues. The allergenic mold type can give off a musty smell that can cause coughing and aggravate allergic or asthmatic conditions.

Other effects of mold on wood can include rashes, dizziness, and breathing issues that affect your respiratory system. If left untreated, mold on wood can continue to grow and spread, potentially causing structural damage to the wood and posing additional health risks to those exposed to it.

Can you get rid of mould forever?

Mould growth can be permanently eliminated by removing the source of moisture in your home, as moisture is the primary factor contributing to mould growth. Without moisture, mould cannot grow, and it will eventually die off. However, controlling other factors such as warmth, spores, and nutrients may be more challenging.

Therefore, it is important to take preventative measures such as proper ventilation, regular cleaning, and controlling indoor humidity levels to minimize the risk of future mould growth.


In conclusion, mold growth on wood can be a serious issue, posing both health risks and the potential for structural damage. To effectively remove and clean mold from wood, it is important to first identify the source of the moisture that is promoting its growth and address that issue. Small areas of mold can be treated with a mixture of dish soap and vinegar, followed by thorough drying and sanding of the affected area.

For larger areas or more severe cases, it is recommended to consult with a professional mold remediation company. By following these tips and taking a proactive approach to addressing mold on wood, you can help keep your home healthy and safe for you and your family.
