You see fungus on your wooden furniture or floor, and it feels like a nightmare. You worry it will ruin the wood forever. But here’s the good news — you can fix it. The exact answer is to clean the wood with a mix of white vinegar or baking soda and dry it completely. In this article, I will show you how to remove fungus from wood step by step in a very easy way that anyone can follow at home, even if you have never done it before.
Find the Fungus and Understand the Problem
Fungus on wood doesn’t always look the same. Sometimes it’s black spots, sometimes it’s white or green fuzzy patches. You might also notice a bad smell or see the wood changing color. This means the fungus is growing, and it is feeding on the wood. Fungus loves dark, wet places. It can grow in areas with water damage, high humidity, or poor airflow. If you don’t take care of it soon, it can spread and cause real damage.
First, look closely at your wooden item. Is the fungus on the surface, or does it go deeper into the wood? Surface fungus is easier to clean. If the wood feels soft or crumbly, the damage might be worse. Also check the air around the wood. Is the room damp or musty? This will help you understand why the fungus grew and how to stop it from coming back.
Now, check for any water leaks near the area. Fungus often starts near water damage. Leaking pipes, windows, or roofs can cause moisture to build up in wood. If you don’t fix the leak, the fungus will return after cleaning.
You also need to protect yourself. Some fungus can be harmful if you breathe it in. Wear gloves, a mask, and old clothes. If you are allergic or have breathing problems, ask someone to help you or take extra care.
Summary:
- Look for black, white, or green patches
- Smell for musty or damp odors
- Touch the wood to check if it’s soft or cracked
- Find and fix any water leaks
- Wear gloves, mask, and old clothes for safety
Clean the Area and Get Tools Ready
Before you start cleaning the fungus, you need to make the space safe and get your tools ready. Start by opening windows and doors. Fresh air helps stop mold from spreading and keeps you safe while cleaning. If you have a fan, turn it on to move the air around.
Next, clear the area. Move furniture and other things away from the wood. Cover nearby items with plastic or old cloths so they don’t get dirty. If the fungus is on a wall or floor, you may want to tape plastic around the space to stop spores from floating to other parts of the house.
Now, gather your tools and cleaners. You don’t need anything fancy. Here’s a simple list:
- White vinegar
- Baking soda
- Water
- Spray bottle
- Scrub brush or old toothbrush
- Clean rags or towels
- Sandpaper (medium grit)
- Vacuum with HEPA filter (if possible)
- Gloves and mask
Mix one part white vinegar with one part water in a spray bottle. This mix kills fungus naturally. If you prefer baking soda, mix one tablespoon of it with water to make a thick paste. Both options work well.
If the fungus is light, you can start with vinegar. If it’s heavier or smelly, try both vinegar and baking soda. Make sure to test a small spot on the wood before cleaning the whole area to make sure it doesn’t damage the finish.
Finally, vacuum the wood gently to remove dust and loose fungus. Use a vacuum with a HEPA filter if you have one. This will stop the tiny spores from spreading.
Summary:
- Open windows and use fans for airflow
- Move items and cover nearby furniture
- Gather vinegar, baking soda, water, brush, and rags
- Make a spray or paste cleaner
- Vacuum the area gently with HEPA filter if possible
Spray and Scrub the Fungus Off the Wood
Now that you are ready, it’s time to start cleaning. Spray the vinegar and water mix on the fungus spots. Make sure the wood gets wet but not soaked. Let the spray sit for 10 to 15 minutes. This gives the vinegar time to kill the fungus.
After waiting, use a scrub brush or an old toothbrush to clean the surface. Rub in small circles, gently but firmly. You will see the fungus start to come off. Wipe the area with a clean towel or rag to remove the mess.
If you see stubborn spots, try the baking soda paste. Rub it on the fungus and let it sit for another 10 minutes. Then scrub again. Baking soda not only cleans but also helps prevent fungus from growing again.
Don’t rush this part. Take your time and make sure every patch is cleaned. Change the towel or rinse it often so you are not spreading fungus back onto the wood. If the towel gets too wet, switch to a dry one.
Sometimes, the fungus might go deeper into the wood grain. In that case, use medium-grit sandpaper and lightly sand the top layer of the wood. Be gentle and go slowly. Only sand the part where the fungus was. Wipe off the dust after sanding.
Keep checking the wood while you clean. If it looks better and smells cleaner, you’re doing it right. If it still smells musty, you may need to clean again or sand a little deeper.
Summary:
- Spray vinegar-water mix and let it sit 10–15 minutes
- Scrub gently with brush or toothbrush
- Use baking soda paste on tough spots
- Wipe with clean towel often
- Sand lightly if fungus is deep in the wood
Dry the Wood Completely to Stop Fungus Return
After cleaning, the most important thing is to dry the wood fully. Fungus loves moisture. Even a little bit of dampness can bring it back. Drying the wood the right way will stop that from happening.
First, use dry rags or towels to soak up as much water as possible. Press firmly but gently. Do not rub too hard, especially if the wood is soft from damage. Change towels often until they come away mostly dry.
Next, let air do the work. Keep the windows open. Use a fan or a space heater nearby. Point the fan toward the cleaned area. This helps dry the wood faster. If you have a dehumidifier, use it in the room. It pulls extra moisture from the air and wood.
Leave the wood like this for at least 24 to 48 hours. Don’t put anything back on the wood until you are sure it is fully dry. If the wood is very thick or if the weather is humid, it may take longer. Be patient. It’s better to wait than to risk fungus coming back.
You can also check dryness by touching the wood. It should feel cool but not damp. If you press a dry paper towel on it and it stays dry, the wood is ready.
Sometimes, after cleaning and drying, the wood may look dull or pale. That’s normal. You can fix this later with polish or oil. The main thing now is to keep it dry.
Summary:
- Wipe wood dry with towels
- Use fan, heater, or dehumidifier for fast drying
- Keep drying for 24–48 hours
- Check by touch or using paper towel
- Don’t cover or use the wood until it’s fully dry
Treat the Wood to Protect from Future Fungus
Now that the wood is clean and dry, it’s smart to protect it from future fungus. This will save you trouble later and keep your wood looking nice. First, think about sealing the wood. You can buy wood sealers at hardware stores. These are clear liquids that go on with a brush. They create a barrier that stops water from getting inside the wood.
If you prefer something natural, you can use linseed oil or mineral oil. These also help protect wood and bring back its shine. Rub the oil on with a soft cloth and let it soak in. Then wipe away any extra oil. This will make the wood stronger and less likely to hold moisture.
For extra safety, you can mix a small amount of tea tree oil with water and spray it lightly on the wood. Tea tree oil fights fungus and smells clean. Don’t soak the wood, just mist it a little. Let it air dry after spraying.
Also, improve the air in the room. Fungus likes still, damp air. Add a fan or keep a window slightly open. If the area is very humid, use a dehumidifier often. You can also keep small bowls of baking soda or charcoal nearby to soak up moisture.
Check the wood every few weeks. If you see small spots or smell something musty, clean it right away before it spreads.
Summary:
- Use wood sealer or oil to protect wood
- Try tea tree oil spray for natural fungus control
- Improve air with fan or dehumidifier
- Use baking soda or charcoal to absorb moisture
- Check the wood often for early signs
Keep Fungus Away with Regular Care
Now that your wood is clean and safe, you must take care of it to stop fungus from coming back. This is not hard. You just need to be aware and follow a few easy steps every week or month.
Start by keeping your wood dry. Don’t place wet cups, shoes, or towels on wooden surfaces. If anything spills, clean and dry it right away. Use mats or cloth under items that might leak water.
Dust and clean wood often. Use a dry or slightly damp cloth. Don’t let dirt or grime build up, as they can hold moisture. Once a month, wipe the wood with vinegar and water mix just to be safe.
Watch out for changes in your room. If the weather is very wet, or if you see water around windows or walls, check the wood too. If you feel the wood is cool and damp, it may need some air.
Keep rooms bright and airy. Fungus grows faster in dark, still places. Pull back curtains, open windows, and let light in. If a piece of furniture is always in a dark corner, move it sometimes to let the air move around.
Teach others in your home to do the same. When everyone helps, your wood will stay beautiful and safe for years.
Summary:
- Keep wood dry and clean up spills fast
- Dust and wipe wood often
- Use vinegar water once a month
- Watch for damp spots or leaks
- Let sunlight and air into rooms

Frequently Asked Questions (FAQs)
Is it safe to use vinegar on all types of wood?
Yes, vinegar is safe for most types of wood, but always test it on a small spot first. Some finished or polished woods may react a little, so it is good to be careful. Mix the vinegar with water to make it less strong. Spray it gently and never let it sit for too long. Wipe it off with a clean, dry cloth. If the wood looks fine after that, you can use it on the rest. Vinegar is a natural cleaner and works very well to kill fungus without harming the wood when used correctly.
Can I leave the fungus if it is only a small spot?
No, even a small spot of fungus can grow and spread fast if you leave it alone. Fungus makes tiny spores that float in the air and land on other parts of your wood or home. If the air is damp or dark, the fungus will grow again. It is always best to clean it right away, even if it looks like just a small dot. The earlier you act, the easier it is to remove and control. Small problems can turn big if you ignore them, especially with fungus.
Do I need to sand the wood every time I see fungus?
You don’t need to sand every time, only if the fungus has gone deep into the wood or left stains. If the surface is clean after spraying and scrubbing, you can skip sanding. But if you still see marks or if the wood feels soft or cracked, light sanding helps remove the damaged part. Be gentle and only sand the area that needs it. After sanding, clean up the dust and let the wood dry fully. Sanding is helpful but not always needed for every fungus problem.
Is it okay to paint over wood after removing fungus?
Yes, but only after the wood is completely clean and dry. If you paint over fungus or wet wood, the problem will come back under the paint. First, make sure all fungus is removed. Then let the wood dry for at least 48 hours. Use a wood primer to seal the surface. After that, you can paint it safely. Painting can also help protect the wood, but only if it’s done after proper cleaning and drying. Never try to hide fungus with paint — it will not solve the problem.
Can I use bleach instead of vinegar?
You can, but bleach is very strong and can damage wood or your health if not used carefully. Vinegar is safer and works well for most fungus problems. Bleach can lighten the wood or make it dry and weak if used too much. Also, bleach fumes can hurt your nose and eyes. If you decide to use bleach, always mix it with water and wear gloves and a mask. Use it only in places with good airflow. Most of the time, vinegar or baking soda is enough and much safer.
Do I need to throw away wood that has fungus?
Not always. You can save the wood if the fungus is only on the surface and not deep inside. Clean it, dry it, and treat it as shown in this article. If the wood is soft, broken, or smells very bad, then it may be too damaged to save. In that case, it’s better to replace it to stop the fungus from spreading. But for light or moderate fungus, you can clean it and keep using it safely after proper care and drying.
Is it safe to touch fungus with bare hands?
No, it’s not safe to touch fungus with bare hands. Some types of fungus can cause skin rashes or allergic reactions. Others can make you sick if you breathe in the spores. Always wear gloves and a mask when cleaning fungus. Even if it looks harmless, it’s better to be safe. After cleaning, wash your hands and clothes well. Keeping yourself safe is just as important as cleaning the wood. Never take chances when it comes to fungus.
Can I use a hairdryer to dry the wood faster?
You can use a hairdryer, but only on a low setting and from a safe distance. Too much heat can crack or damage the wood. It’s better to use fans, heaters, or natural airflow. If you use a hairdryer, move it slowly and don’t keep it in one place too long. Always keep checking the wood to make sure it doesn’t get too hot. Hairdryers can help in small spots, but for full drying, fans or dehumidifiers are safer and better.
