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.
Prepping To Clean The Mold
How To Prevent Mold Forming On Wood
If a leak occurs in your home, immediate action is key to prevent mold growth. If you can dry the affected materials within a day or two , chances are mold wont grow.

Black Mold Removal Using Vinegar
White vinegar is a mildly acidic product that cleans, deodorizes, and disinfects. It can also kill 82% of mold species, including black mold, on porous and non-porous surfaces. You can use it safely on most surfaces, and its offensive odor goes away quickly.
Pour undiluted white vinegar into a spray bottle. Because white vinegar contains only about 20% acetic acid, adding water makes it less effective. Spray the vinegar onto the moldy surface and leave for an hour. Finally, wipe the area clean with water and allow the surface to dry. Any smell from the vinegar should clear within a few hours.
Stop The Spread Of Mold

Items that have been sitting near the mold colony often are dusted with spores and growth. Bookcases, closets, and pantries are especially susceptible, since we’re prone to “dust around” long-term items like earthquake kits, read books, and clothes you’ll wear once you renew that gym membership. Before moving the infected items, clean them throughly so the mold doesn’t move into a new home. Here’s how:
*NOTE: Do NOT mix bleach with cleaning products that contain ammonia. It creates a toxic vapor.

Different Types Of Mold
Molds come in many different forms in fact, according to the Centers for Disease Control and Prevention, there are probably tens of thousands of types of molds, if not more. Molds play an important role in breaking down leaves, plants and trees. While many molds are harmless, harmful types in enclosed places can lead to respiratory distress, manifesting itself in symptoms that include stuffy noses and wheezing. The effects will be more intense for those who are allergic to that mold or have asthma. Molds responsible for breaking down natural materials, like wood and leaves, can damage the structure of your home. Everyone has an aversion to that.
Lets take a look at a few different types of mold that you might commonly encounter in various areas of your home.
Treat Wood To Prevent Reinfestation
A wood mold infestation may recur in a structure as long as conditions remain conducive to fungus growth. Water damage or high relative humidity levels provide the moisture and wood contains cellulose, which is a rich source of nutriment for mold. While it is crucial to take measures to stop leaks or lower excessive moisture, treating wood can also prevent a problem from recurring.
If a single application of vinegar does not get rid of mold, consider reapplying this treatment at a stronger concentration, up to full 5% or 6% strength. In some cases, Borax, an alkaline mineral salt cleaner, may be a better choice. This substance gets absorbed under the surface of the wood. Once wood treated with Borax or vinegar has completely dried, furniture or building materials are ready to be treated with a mold-resistant finish, primer and paint.

Other Types Of Mold On Walls
Black may be the image you picture in your mind when you think about mold on walls. These spores actually come in many different colors and each color presents a different type of mold. Grey, olive-green, brown, blue, green and white molds are all commonly found on walls. Each color is a different type of fungus, but all molds must be killed and cleaned out of the home immediately. Left undisturbed, any color of fungi spores will continue to grow and spread in damp areas. No matter what color of spores you are seeing, know that it is harmful to your lungs and health. Access the area and decide the best way to clean and disinfect the area.
How To Remove Mold From Drywall
How the problem is handled on drywall depends on the condition of the sheet rock itself. If the material is unpainted or unsealed it is much more porous so it will absorb the spores right through to the back of the surface. In most situations, if you have a problem on the outside of sheetrock, it is probably on the inside as well. If you find it on unsealed sheetrock, the only thing you can do is remove the section that is affected and replace it. It is important to cut out a large enough section of the sheetrock to expose the wood behind it. Molds cannot be removed from insulation, so completely removing and replacing it is necessary.

Products For Removing Mold From Wood
There are numerous ways to get rid of mold from wood. You can either use eco-friendly, natural products or chemical products.
Different products are suitable for different types of wood. It depends on whether the wood has been painted or stained, making it non-porous, or if its unpainted and unstained, making it porous. On non-porous wood, mold remains on the surface, but if on porous wood, then the roots will be within the wood.
Take Note
Remove Mold From Plaster Walls
Under the right conditions, plaster can absorb a large amount of water and if the water is allowed to sit, black mold may appear. Cleaning a plaster wall will help to temporarily remove the problem, but to prevent the risk of it returning and/or spreading, itâs best to improve the air circulation with a fan or install a dehumidifier.

How Do You Get Mold Stains Out Of Wood
Before you remove the stains, ensure you are safe by dressing in appropriate gear that covers your skin. Use a respirator to avoid inhaling mold spores. Shield your eyes with eye goggles as the mold irritates the eyes. Protective clothing will keep mold spores from your attire and do not forget rubber gloves.
Clean the area in question, or vacuum clean it to curb the spread of mold. Study the wooden surface to determine what type of treatment to use. The wood may be painted or untreated.
If it is painted, wiping the surface with hot water and any detergent will resolve the issue. This is because the mold cannot penetrate through paint or any treated wood.
For untreated wood, clean the surface with water, detergent, and some bleach. What most people struggle with is, “does bleach kill molds?” It helps kill molds if used with water and works only if the mold is on the surface. After sponging the mixture on the wooden surface, you let it dry or use a dehumidifier to dry the area faster. This is necessary as excess water on the wood increases mold growth.
To remove the mold stains on the surfaces you have cleaned, you need to do a deep cleaning. The stains are hazardous to your health, so exercise caution to not increase mold growth instead of getting rid of it. Sanding the affected and cleaned area may remove the mold stain. If the wood is darker, discoloration will occur. Apply varnish or new paint after coating the place with mold-killing primer to conceal the discoloration.
Use Water To Wash Off The Loosened Mold

After scrubbing, get as many buckets of water as you will need and pour it across the surfaces you have scrubbed. This will clear the areas of the mold and the bleach altogether.
After the wash, make sure you mop up the floors to keep them dry. You should also leave the doors and windows open for continued ventilation, as this will help the surfaces dry faster.
Toxic black mold removal can not be truly complete without watering down the walls and drying them out. Do not forget to take this simple but vital step.
