Mold belongs to the fungi group and is a greenish-grey matter that grows in areas that are high humid levels. Mold emits an earthy pungent smell. There are different types of mold that can be identified by their color. We have black mold-greenish-grey, white-white, brown, and black. You can easily notice the presence of mold on wooden surfaces in your home when you see grey rings. These rings are a common feature near areas that have had exposure to water.
What Does Mold on Wood Look Like?
It is hard to identify mold on wood because naturally, wood comes in different shades of colors. And the growth of mold is gradual, that you might not clearly spot the color difference.
Also, since there are different types of mold, we have white mold that has a white appearance on wood and is loosely attached. The black and grey mold is also found on wood after the wood has previously been soaked in water and was not properly dried.
How to Remove Mold from Different Types of Wood
For you to effectively clean and prevent any type of mold from growing back, you need to first identify the cause. You, therefore, have to prevent conditions that favor the growth of mold.
When the mold is not properly cleaned, it leaves behind stains. It should therefore be properly removed using the correct cleaning agents and tools.
General ways of cleaning mold off surfaces are basically by scrubbing it off the surfaces and by use of the correct cleaning agent. It is also important to use wood-friendly cleaning agents that do not cause damage to your wooden surfaces.
As a general concern, for your cleaning to be effective, if possible clean your wooden from the outside for the portable ones. And for the ones attached to your house, clean while your windows and doors are open to allow them to dry well. Also, move them away from the wall. This allows for good ventilation.
Make sure that you wear protective gear. And vacuum the area after cleaning so that you avoid the spread of mold spores. If it is necessary, sand the area to eliminate residual mold.
Also, carefully select an appropriate cleaning agent to avoid damaging the wooden surfaces or totally discoloring them. It is also advisable that you apply a protective coat on your wooden surfaces so as to minimize the chances of the mold growing back.
Let us consider specific situations:
a. Wooden Chair
Here, there are several ways which include wiping the chair with diluted dish detergent or beach, among other methods.
Spray the chair with your preferred detergent, using a soft bristle brush, and scrub gently in a circular motion. Rinse the chair with clean water and allow it to dry.
Only use bleach for stubborn mold stains. Remember bleach discolors surfaces. Also, consider using sandpaper if the mold stain is really tough. Otherwise, sandpaper also discolors your chair.
b. Wooden Cabinet
First, remove all the contents from the cabinets. Spray the cleaning agent you settled on onto the cabinets. Using a soft bristle brush, gently scrub the mold off. Rinse thoroughly with warm water and a soft rag. Allow them to dry properly before using them.

e. Wooden Door
Removing mold from a door is quite complex, for wood is porous. At times, you might be cleaning the outer surface yet the source might be deep in between the wood. If your door is painted, however, it would be hard for the mold to penetrate through.
Use the required detergent, and spray it on the door. Using a soft bristle brush, scrub the mold off in a circular motion. Rinse the door with clean water, wipe it and allow it to dry.
f. Composite Deck
This is more difficult due to the porous nature of the composite deck. Ensure that you remove all items and expose the whole surface that contains mold. Ensure that the deck is dry, then apply the cleaning agent. Gently scrub the mold. Rinse it up with clean water and allow it to dry.
g. Wooden Deck
Clear off the area. Make sure that you expose all the surface that has been infected with the mold. Then use the cleaning agent that you settled on and wipe off or scrub the mold. Allow it to dry properly. You can then put back whatever was there.

How to Remove Black Mold from Wood
First, you need to find out whether the mold is loosely attached to the surface of the wood or whether it is a big bulky mass. For the loosely attached black mold, it is quite easy to remove using the common cleaning and bleaching agents. The big mass buildup of the black mold is a bit cumbersome and, in most cases, you would need the help of an expert to have it thoroughly cleaned out.
For this exercise, you need a shop vacuum, bleach, N-95 respirator or mask, heavy-duty cleaner, drywall saw, painter’s tape, safety glasses, oil-based primer, scrub brush, and plastic garbage bags, rubber gloves, paintbrush, utility knife, and sandpaper.

1. Identify a cleaning agent
This should be a good cleaning agent that penetrates the wood and kills the fungi. There are cleaning agents like distilled vinegar, bleach, and rubbing alcohol, among others. However, you should carefully select the cleaning agent so as to avoid a violent reaction of the detergents from happening, that is, avoid mixing ammonia with any bleaching agent.
2. Wear protective gear
This includes putting on gloves and long-sleeved shirts depending on the cleaning agent that you settled upon. Other safety gear that you can consider include protective goggles, a respirator, and coveralls. If you do not have all these protective gear, you can always improvise but choose good quality materials that can easily be cleaned or disposed of after the cleaning.
3. Vacuum the surface
Make sure you use a vacuum with a HEPA filter in sucking up mold and mold spores from the surface of the wood. As you vacuum, ensure the mold gathered is in a tightly sealed plastic bag for disposal. Otherwise, you may simply spread it to other areas in the home.

6. Dry the area
When you are satisfied that you have thoroughly cleaned the affected area, remove all the residue from the area and allow it to dry properly. You need to carefully put all objects that came into contact with the black mold into the garbage bags for disposal. To be more cautious, tie the garbage bag with tape so as to avoid the mold debris from spilling and contaminating otherwise clean areas.
Sometimes, you might have properly carried out the cleaning process but you still see the mold on the wooden surface. In such a case, you will need to reapply the cleaning mix and allow it to be absorbed for some time then scrub the surface slowly again.
Cleaning tips for mold on wood
When cleaning mold of any type from wooden surfaces, follow these tips:
- Avoid cleaning wooden surfaces with bleach if the mold is deep inside the wood since it doesn’t get into the wood fibers. Instead, only the water in bleach solutions will enter the wood. This will instead provide better conditions for the further growth of mold instead of killing it. However, bleach kills mold effectively when it’s on the surface of the wooden surface.
- It’s advisable to clean if it is furniture, from the outside so as to avoid contaminating other surfaces with the black mold since it spreads in the air very fast.
- Use a vacuum to suck all the mold spores that might have escaped into the air. This ensures that your home is free of mold in general. Empty the vacuum canister from outside into the garbage bag and have the bag sealed properly to avoid the escape of the black mold particles.
- Very light surfaces with black mold are easy to clean by just having them aired under direct sunlight. This will eradicate the earthy smell and the mold coloring will also disappear after some time. You can also spray your furniture with a mixture of water and vinegar before airing them outside.
- You can also remove light mold by spraying your furniture with cheap vodka. After spraying, air the furniture under direct sunlight. You might need to paint your wooden surfaces with anti-molding substances. These are gotten from the paint shops and are mixed with normal paint. Their work is to prevent black mold from growing back to your wooden surfaces or furniture.
With these tips, cleaning mold from wood shouldn’t be hard. Some of these methods can be used to remove mold from stucco. If you can’t do it by yourself, consult an expert instead.
