Sand The Affected Area
As we mentioned above, there are varying levels of fungi growth and different mold species. If you catch the problem soon enough, the mold on wood may just be on the surface. But if its been growing for a while, the fungi roots may have penetrated deeper into the wood.
If thats the case, a single scrubbing will not prevent mold re-growth. To get deeper into the wood, you need to use a sanding process. This process is the same as you would use if you were to research how to remove mold from drywall. The treatment needs to penetrate deep into the affected material.
At this stage, youll want to put on the safety goggles to prevent wood chips from getting in your eyes. Either by hand or using an electric sander at a low-abrasive setting, lightly sand the area you cleaned in Step 3. Then apply the solution in the spray bottle and scrub again in the same area.
Repeat the process until you have scrubbed away any remaining fungal residue.
TIP: Start with the lowest level of grit in your sanding material and build up from there. Start with #100-grit sandpaper for the first pass. If this doesnt penetrate deep enough into the wood to get rid of all the mold, move up to #220-grit sandpaper and repeat the scrubbing and sanding process. Also, remember when dealing with furniture that some types of wood damage more easily from sanding than others. When in doubt, consult a professional before you start to avoid damaging your furniture.
Mold On Wooden Furniture
Fungi spores are a constant part of our indoor and outdoor surroundings. Unfortunately, they carry no good with them. Your wood furniture may come under attack from these fungi eventually causing damage as well as health complications. Wood furnishings are high prone victims of mold attack if exposed to certain temperatures and moisture levels. Mold survives on any cellulose-based matter, in which wood furniture provides. If any of your outdoor or indoor wooden furniture starts to home fungi, you might want to know how to remove it.

Removing Mold From Wood Floors And Ceilings
If you have surface mold on your wood floor or ceiling, your first step needs to be identifying the source of the mold. This means that youll need to look for any signs of water damage that may have caused the mold.
Then, youll need to clear away any furniture in the room. This helps to expose the entire area that has been affected by mold.
Next, prepare a spray bottle of vinegar, dishwashing soap and water. Spray on the affected area, allow it to sit for 10 minutes and wipe with a cloth. This will kill any live mold before it spreads.
Make sure to wipe the area with a clean, wet cloth to remove any solution once the mold is gone. Once the floor has completely dried, you can put furniture back in place. However, we recommend that you check the area over the next few weeks to ensure that the mold has not returned.
If the mold has penetrated the wood floor or ceiling, you can try using either hydrogen peroxide or a professional chemical solution. Apply to the affected wood and let the solution soak in for a few minutes, then use a hard bristle brush and scrub the mold.
Keep In Mind
Cleaning Mold From Wood Trusses And Cross
In an area of high levels of mold growth or moldy dust and debris, the irregular surfaces formed by wood trusses and alsoby older wood cross bracing between floor joists prevents thorough cleaning of surfaces and creates many dust collectionpoints.
A similar construction detail where significant moldy dust reservoirs may be left in place is the upper surface of woodfurring which has been nailed across the under-side of floor joists to support ceiling tiles.
Because the surfaces formed by trusses and cross bracing can form a significant dust and debris reservoir, I always checkthese areas during a mold remediation clearance inspection. If work has been hasty or incomplete, these are among the firstareas to be under-cleaned.
Spray process cleaning, media blasting , and HEPA vacuuming are effective for these areas.

Put On Protective Clothing
Prior to interacting with the mold, put on protective clothing, including a long-sleeved shirt and long pants. Wear old clothes because any bleach splatters will cause permanent stains. Also, wear a protective air mask, rubber gloves, and safety goggles. If possible take the mold-infested wood outside when cleaning to prevent spreading spores indoors. If you must remain indoors, close doors or use plastic sheeting to shield other areas.

Treat exposed molded subflooring with a mixture of 1 cup of borax and 1 gallon of water or an EPA-registered mold removal product. Spray the solution on the moldy plywood. You can also soak affected subflooring with a brush broom. Wait 10 minutes, scrub the area, and repeat the process two more times.
Power Tip: Repeated applications allow a treatment to penetrate and kill mold deep in the plywood.
Determine How Far The Mold Has Penetrated
For building materials such as wood floors, mold has the ability to penetrate deep within the surface that extends beyond visibility. But to determine exactly how far it has spread, press into the affected area with a screwdriver. If the wood is soft and spongy, it has spread below the floorboards, which will require replacing the board itself. Follow the listed steps below to learn how to remove mold that has penetrated through wood floors.

Remove Surface Area Of Mold From Wood Floor
After the mold is completely dry, use 100-grit sandpaper to scrape in circular motions to remove the surface mold. Then use 200-grit to scrape away the fungus that has penetrated deeper within the wood. For the most stubborn areas, you can use a metal spackle blade to have all mold in the deepest areas removed. Finally, when you are done, smooth out the area using 200 or 250-grit sandpaper.

What To Do If Mold Persists
If the mold stains still remain, the wood surface will need to be sanded to remove the spores that have deeply penetrated the wood. If you are not familiar with wood sanding or refinishing, ask questions at a home improvement store about the right sandpaper grit to use for your situation. After sanding and vacuuming away all of the grit, the wood should be refinished or sealed to help prevent future damage.

Reader Question: How Should We Clean Moldy Wood Framing In Our New Home
We are building a new home, the wood framing has mold, the walls are still open. How should the builder clean or remove the mold? – Linda Lewis 4/7/2013
Thanks for the question Linda.
If the mold is ONLY the cosmetic black mold that we describe
at BLACK COSMETIC MOLD then it really is only cosmetic and could be left in place.
There are two difficulties with this:
- First you may have trouble recognizing the cosmetic mold I describe in that article, though sometimes the growth patterns make it clear. To address this you could spend roughly $50. to send a representative tape sample of the mold to a mold test lab for confirmation.
- Second, while the black mold I describe is indeed harmless on framing lumber and virtually always came in on the lumber from the lumber yard, also one wants toWatch out: in some cases, particularly on lumber that has been wet, or on treated lumber, my own field and lab tests have found Aspergillus sp. and Penicillium sp. growing among the harmless black mold.
So we might want to clean the lumber.
I tend to stay away from labor intensive approaches and from incomplete approaches . Keep us posted and send along some photos if you can as what you learn may help others.
This article series includes advice on cleaning mold found on surfaces of un-finished wooden building materials such as framing lumber , and building roof, wall, and floor sheathing such as plywood, tongue-and groove pine boards, and other structural wood surfaces in buildings.

How To Remove Mold On Wood Cabinets
If the mold is truly surface mold, then you might be successful at removing most of it with the proper products and a little elbow grease. The sneaky thing about mold is that it roots quickly and deeply and may have already penetrated all the layers of your cabinet. You wont know if that is the case until you remove the surface mold and see if you get any regrowth.
If you believe that the mold on your cabinets has penetrated more deeply, the best thing you can do is to follow the steps above but instead of scrubbing the cabinet with a brush, sand the surface layer away. This of course means that as your final step, you would need to refinish or repaint the cabinets.

Answer: Physically Clean Moldy Wood Surfaces Dry The Wood Flooring Before Installation
Here we are discussing cleaning mold off of wood flooring products that have not yet been installed in a building. If your concern is with mold on the visible surfaces of wood flooring already installed in a building, or on the under-side of wood flooring or subflooring already installed in a building, the wood surface cleaning discussed here still applies, but you should also see HIDDEN MOLD in FLOOR / SUB-FLOOR. Also see MOLD CLEANUP – WOOD FRAMING & PLYWOOD where we describe methods for cleaning wood surfaces in general.
Without a mold lab test we don’t know from the moldy flooring question above if you are seeing mold or something else on soiled wood flooring, but it is reasonable to guess that a substance is mold based on its physical appearance , especially if the flooring has been exposed to water, wet conditions, or high humidity.
Except where major costs are at issue that would be effected by a determination of the type of material or mold present, or where there are other reasons to test for mold, in our opinion testing is not necessary for small mold cleanup jobs . For help in deciding if it is appropriate to test for mold, see Reasons to Test for or Identify Mold and see MOLD / ENVIRONMENTAL EXPERT, HIRE ?.
At right our moisture meter is measuring the moisture level of a different wood floor, showing that the moisture is in the danger zone for forming mold, rot, insect damage, and floorboard cupping.
