Guide on How to Remove Mold from Wood

What is mold? To simply put it, mold is any species of microscopic fungi that grow in the form of multicellular filaments called hyphae. Mold generally floats around us undetected until it gets optimum conditions such as warmth and moisture, and that’s when it begins to grow. It thrives well on almost anything organic like ceilings, clothes, floors, etc. Wood can be a habitat for mold as it can soak and hold water; hence mold can survive easily here.

It is sad to find your beautiful furniture infested with mold. So then the question becomes, how to remove mold from wood? The trick is to make sure it hasn’t spread as that makes it harder to eradicate it completely. In this article, I will take you through the steps on how to remove mold from wood.

What Tools Do We Need To Use?

  • Dishwashing agents
  • Sandpaper
  • Chlorine Bleach
  • Water
  • Soft-bristled scrub brush
  • Sponge
  • Soft cloth
  • Safety gear (goggles, gloves, and air mask)

Step 1. Wear Your Protective Gear

Before embarking on this procedure, the first thing is to take care of ourselves. Mold is harmful to human health if it gets into your body, especially your lungs. Again we will be using chemical agents that can be dangerous to you if they come into contact with your body, and we need to be protected. Seal off the area you want to work so that the spores do not spread to the rest of the house. Consider opening up the windows and using a fan to facilitate aeration.

Step 2. Prevent the Spread Of The Mould

First and foremost, you need to find the root cause of the problem. This might be a leakage, floods, dampness, and you should cut off this source before trying to remove the mold from the wood.

Do this by moving your infested wood outside to avoid spreading it to other items. Unfortunately, if you don’t have the luxury of doing it outdoors, ensure you open doors and windows to allow ventilation. Additionally, place the piece of wood on a trash bag, then use a vacuum (with a HEPA filter) and vacuum the loose mold on the wood to ensure it doesn’t float in the air. As said earlier, it can spread to other things in your house and also can be harmful to your health if ingested into your body.

Step 3. Wash Down Your Painted or Sealed Wood

Painted wood is usually easy to remove mold. This is because paint acts as a repellant for insects as well as mold. So, if the wood has not been affected much, wash it out with dishwashing detergent or just soap and water. Use your bristled brush to scrub the surface of the piece of wood. If the mold has penetrated the wood, you need to sand it to comove the stain completely. Try not to saturate the wood with water, and if in case it happens, remove the excess water with the sponge.

Step 4. Exterminating the Mould

White vinegar will kill almost 82% of mold species, and you can use it on virtually any surface. The good thing is that its odor clears very fast. If the mold is less concentrated and severed the piece of wood, spray distilled white vinegar on the area. Allow the wood to rest outside until the stain has completely vanished and then buff the surface with a cloth.

If the stain has penetrated and cannot be removed by vinegar it is time to take more drastic action. Mix a part of the dishwashing detergent with a half cup of chlorine bleach and warm water. Apply the mixture to the stain and scrub gently with the bristled brush and let it air dry. Finish off with a soft dry cloth to bluff.

On the brighter side, there are other ways to remove mold without resulting in using harsh chemicals used to eradicate mold. Some of those chemicals can be as dangerous if not handled by a professional. Some of the natural ways include:

Use Of Hydrogen Peroxide

Hydrogen peroxide is not new to many of us. You can find it in many of our medicine cabinets or first aid kits. It is a solution with antifungal, antiviral and antibacterial capabilities. Due to its antifungal ability, we observe that it is an effective mold treatment. Put a 3% concentrated solution of hydrogen peroxide in a spray bottle and spray the affected area. Leave it for about 15minutes then scrub the area to remove the stains. Ones it’s out, use a dry cloth to wipe down.

Using Baking Soda

From being a common item in our kitchens, baking soda is an ideal absorbent of moisture that could attract mold. Combine ¼ tablespoon of baking soda to a spray bottle with water and shake till fully dissolved. Then spray the infected area. Use a bristled brush to scrub and remove the mold from the surface. Rinse the surface with water to remove any left-over mold or spores. Finally, respray the area to kill any mold that may have been left behind and let it air dry.

For hard to remove mold, mix two parts baking soda, one-part white vinegar and one-part water. Mix the mixture until it becomes a thick paste and spread it on the affected areas. Let it dry off and scrub thoroughly until the stain comes off. Rinse with water and use a dry cloth to wipe down.

Treating With Lemons

Lemons are known to be a natural deodorizer, antiseptic, bleach, cleaner, and stain remover. The high concentration of acid in lemons makes it easy to remove mold leaving the surface disinfected. Squeeze a few lemons in a container and pour over the infected area. Let it sit for a few minutes then scrub. Rinse with water and wipe down the residual water. Let it dry off.

Step 5. Sanding and Resealing

If the stain persists and has refused to get out, it’s time to sand out the stain. Sanding will remove any left-over stains that have deeply penetrated the wood. After its gone, it’s time to refinish or seal the area to prevent further damage. Note, if this is a process that you cannot consult an expert for help.

Tips To Consider

  1. If your wood cannot be taken outdoors like your floorboards, use a fan and heater to remove the spores from the room and to keep it aerated. The heater will evaporate the moisture from the wood. Make sure not to place them near the wood; otherwise, it will just irritate the mold more. Let them run for at least four hours. The airflow ensures there is no further spread of the mold.
  2. Sand in a circular motion to remove the surface mold. Use a 100 or 200 grit sandpaper.
  3. Most of our bathrooms have wooden doors. So keep the bathroom door open after showering to allow the moisture out.
  4. Get a dehumidifier if you don’t have one in your home. Keep the humidity levels about 30-50% to stop the growth of mold.
  5. Always use protective gear when trying to remove mold from any surface.
  6. Never mix ammonia or any detergent containing ammonia with bleach as it produces a very poisonous gas.
  7. You must remove the source of moisture that is giving out moisture, which causes the mold to grow, e.g. leaks, dampness from cooking or bathing, floods, etc. Ensure that the spread of mold is stopped.
