Solid wood furniture can be a big financial investment, which is why it can be a major bummer if you discover mold on one of your favorite pieces. The good news is, there are steps you can take to get your wood furniture back into good condition. Keep reading for a thorough guide on how to remove mold from wood furniture.

Why Do I Have Mold on My Wood Furniture?

You may be surprised the first time you spot mold on wood furniture, but unfortunately, mold can make its home on many different surfaces. Mold growth on wood furniture is a more common problem than many people realize, and there are several reasons why it might occur.

  • Moisture: Mold needs moisture to grow, and wood furniture can absorb moisture from the air, especially in humid environments. If the furniture is stored in a damp area or if there's a leak in your home, it can create the perfect conditions for mold growth.

  • Poor ventilation: Insufficient ventilation can trap moisture indoors, creating an environment conducive to mold growth. This is especially common in closed, unventilated spaces like closets or storage rooms.

  • Direct contact with moisture: If the wood furniture comes into direct contact with water or another liquid, it can provide the moisture necessary for mold to grow. This can happen due to spills, leaks, or even cleaning the furniture with excessive water.

  • Lack of sunlight: Sunlight can help to inhibit mold growth. Furniture placed in dark, poorly-lit areas is more prone to mold infestation.

  • Existing mold spores: Mold spores are everywhere in the environment. If the conditions are right, these spores can land on the furniture and start to grow.

How to Identify Mold on Wood Furniture

It shouldn’t be too hard for you to see if your wood furniture fell prey to mold. When inspecting furniture, make sure to check all surfaces, including crevices, joints, and hidden areas. Here are some of the common signs of mold infestations on wood furniture. 

  • Color: Mold on wood can appear in various colors, including black, green, gray, white, or brown. It might look fuzzy, slimy, or powdery.

  • Texture: Mold can have different textures, ranging from fluffy to slimy.

  • Scent: Mold often produces a musty, earthy smell. If you notice a persistent, unpleasant odor near the furniture, it might indicate mold growth.

  • Discoloration: Look for any unusual stains or discoloration on the wood. Mold can cause the wood to darken or become discolored.

  • Warped or distorted wood: Prolonged exposure to moisture can cause wood to warp or change shape. If your furniture shows signs of distortion, it might be due to mold growth.

  • Deterioration: Mold can lead to the deterioration of wood fibers. Check for any signs of crumbling or weakening of the wood structure.

  • Allergic reactions: If you or others in your household experience allergic reactions, such as sneezing, coughing, or skin irritations when near the furniture, it could be a sign of mold presence.

If you're uncertain about whether or not what you're seeing is mold, consider hiring a professional mold inspector. They can perform tests to confirm the presence of mold and identify the type.

How to Remove Mold from Wood Furniture

Do you have to throw away everything with mold on it? The good news is, that if you do find mold on your furniture (and you can even remove mold from fabric furniture), there are some simple steps you can take to remove it.

Assess the Damage

Begin by inspecting the furniture to assess the extent of the mold growth. Identify the affected areas and determine whether the mold has deeply penetrated the wood or is confined to the surface.

Isolate and Ventilate

Move the affected furniture to a well-ventilated area, preferably outdoors if possible. Proper ventilation is crucial to prevent inhaling mold spores during the cleaning process.

Wear Protective Gear

Before you really get to work, put on gloves, a mask, and safety goggles to protect yourself from mold spores and cleaning solutions. Long sleeves and pants can also prevent skin contact with mold.

Remove Surface Mold

Use a soft brush or cloth to remove the surface mold from the wood gently. Avoid brushing vigorously, as it can release mold spores into the air. Dispose of the brush or cloth after use.

Clean with Mild Detergent and Vinegar

Once you remove the surface mold, you will prepare a solution of mild detergent and water. Dampen a clean cloth with the solution and gently wipe the moldy areas. Avoid oversaturating the wood. Dry the furniture thoroughly with a clean, dry cloth afterward. 

You can also apply white vinegar to the wood as an extra precaution. White vinegar is an effective natural mold killer. Mix equal parts of water and white vinegar in a spray bottle. Spray the affected areas and let it sit for an hour. Wipe the furniture with a damp cloth and then dry it completely.

Sand the Wood (If Necessary)

If the mold has penetrated the wood deeply and caused stains, you may need to sand the affected areas lightly. Use fine-grit sandpaper to remove the stained layer. Be cautious not to damage the wood's integrity. Taking this extra step will turn this project from a quick and easy one to a fairly time-consuming one, but it may be worth it to save valuable wood furniture. 

Apply Anti-Mold Solution (Optional)

To prevent future mold growth, consider applying an anti-mold solution or wood sealant designed to resist mold. Follow the product instructions carefully and apply it to the entire surface of the furniture.

Seek Professional Help (If Needed)

If the mold infestation is extensive, if you have health concerns, or if your efforts do not effectively remove the mold, it's advisable to seek professional mold removal services near you. Professionals have the expertise and equipment to handle severe mold problems safely. Mold remediation costs can vary significantly, so make sure you ask around for a few different quotes.

How to Prevent Mold Growing on Wood Furniture

To prevent mold growth on your wood furniture, consider the following measures:

  • Keep the area dry: Ensure the area where the furniture is kept is well-ventilated and dry. Use a dehumidifier if necessary, especially in areas prone to high humidity.

  • Avoid direct water contact: Be cautious about placing drinks or vases directly on wooden surfaces. Use coasters or placemats to protect the wood from moisture.

  • Clean and dust regularly: Regular cleaning prevents the buildup of dirt and dust, which can create a habitat for mold. Use a mild cleaning solution suitable for wood surfaces.

  • Arrange proper storage: If storing wooden furniture, make sure it's in a dry, well-ventilated area. Consider using moisture-absorbing products like silica gel or activated charcoal in storage spaces.

  • Expose to sunlight: If possible, position the furniture where it can receive some sunlight. Sunlight can help to prevent mold growth.

  • Promptly address leaks: If there are leaks in your home, fix them promptly. Even small leaks can lead to significant mold problems over time.

  • Regular inspections: Periodically inspect your furniture and the areas where it's placed for signs of mold. Early detection can prevent extensive damage.
