How To Remove Toxic Black Mold From Wood!

Mold has many forms, and like termites it can break down wood surfaces. If you dont see mold or are unsure if what you see is mold, then look at these signs that what you see is mold.

  • wood warping, cracking, or peeling
  • continued growth
  • appears in a low light area with high moisture content

You want to always keep your home safe. The money spent on an inspection would be worth it.

Getting Rid Of Mold Naturally

So what should you use? Vinegar. Why? Vinegar will penetrate porous surfaces to kill both the mold on top and the membrane beneath to prevent it from coming back again. It will work on solid non-porous surfaces as well making it the all-around best choice for mold removal. Vinegar can be found in just about any grocery store, its cheap and its effective for getting the job done.

Do Baking Soda And Vinegar Clean Mold

Combining vinegar with baking soda forms carbonic acid. While this compound isnt strong enough to kill mold, its effective enough to get rid of the spores. However, you should be careful, as this mixture can damage some wooden finishes and sealants.

Baking sodas abrasiveness should be taken into account when deciding how to clean mold off wood. So, if you opt for the baking soda and vinegar combo on wood, dont scrub it forcefully onto the surface, and rinse away after 10 to 15 minutes.

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.

Removing Mold From Wood Floors And Ceilings

How To Clean Mold On Wood

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.

Protecting Yourself While Cleaning Moldy Surfaces

When cleaning mold from any surface, wear protective gear to keep yourself safe. Wear a respirator or air mask of some sort during mold removal to prevent mold spores from entering your lungs. Safety goggles and rubber gloves need to be worn at all times when cleaning up the mold to protect you from certain cleaning products, as well as mold spores.

If using bleach, wear protective outer clothing or old clothes as the bleach may cause stains. To remove mold from a large area like one that has a strong, musty smell, or one with extensive water damage, you not only want to wear protective gear, but you also want to take a few extra precautions.

These extra precautions prevent the mold from spreading throughout the rest of the house and will protect you from breathing in the spores and fumes from cleaning products you are using. Use an old box fan to ventilate the area you will be throwing it away when done as the spores are impossible to clean off the fan.

Moisten moldy areas while working, turn off furnaces and air conditioners while working, cover ducts and vents, and always leave your wet/dry vacuum outside double-bag and tape all moldy materials before throwing them in the trash.

How Much Mold Must Be Removed

Following a properly executed mold cleanup, if there is a future mold problem in a building it is unlikely to be due to having left behind an “inoculation” of problem mold, and more likely to be due to a new building leak that was left unattended.

Good practice for the extent of and means of physical removal of moldy debris varies by material.

For drywall we remove all visibly moldy material and continue removing drywall to no less than the next adjacent stud, rafter, or joist.

For fiberglass or other porous building insulation which has been wet, we remove all suspect insulation and all insulation within 24″ of the suspect material. However if moldy and wet conditions were long-standing in a building, removal of all of the insulation may be necessary.

For building insulation that has been exposed to dusty conditions or high levels of airborne mold it is often more cost effective to simply remove the material, clean the surfaces, and re insulate than to spend that same money on testing the insulation for mold.

Generally it is less costly to remove and discard more material than to “finish” the job and then discover that it needs to be done over again because the initial work was insufficient.

Framing lumber, or roof or wall sheathing that is not rotted does not need to be replaced. Unless framing lumber has been actually damaged, such as by rot, replacing it due to mold contamination is not justified and wouldbe improper.

Five: Protect And Prevent

If you correctly identified the cause of the issue, that means that moisture shouldnt be a problem anymore .

To prevent further damage or recurring issues, keep your wood furniture dry, clean, and disinfected.

Mildew-resistant paints in all colors for wood surfaces are available at paint, hardware, and some department stores. These products are formulated with fungicides to combat mold and mildew growth.

Applying a mildew resistant paint is a great way to seal your efforts and prevent further infections.

If you feel that any mold remains, you might consider sanding your wood furnitures surface and repeating the above steps before applying a mildew resistant paint.

It may seem contrary to protecting the wood, but sanding is the only way to reach the mold deep within the wood.

Once the wood is clean and smooth and shows no sign of mold, then you can safely apply your stain or finish and your resistant paint.

Treat Wood To Prevent Reinfestation

How To Remove Mold: Mold Remediation  The Family Handyman

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.

How To Remove Mold From Wood Furniture And Other Surfaces

For minor infestations, a solution of household detergent and water with a soft-bristled brush or sponge may be enough to remove mold from the wood in your house. In more difficult situations, meticulous sanding or even replacement may be required. Keep in mind that even the invisible mold spores can cause health problems, so only specialists with appropriate training and removal procedures should handle severe cases.

Gently scrub off the mold from the afflicted wood surfaces with the brush or sponge dipped in the mixture. After youve gotten rid of all visible signs of mold, you may be tempted to give the wood one last rinse. Dont do this. Adding more water to the area might actually produce new mold, defeating your efforts. The objective is to thoroughly dry out as quickly as possible and minimize the chance that it will support mold development.

We strongly advise against the use of bleach. Mold may grow in any nook and cranny on porous surfaces such as drywall or wood, making it difficult to remove all of the spores from inaccessible locations. After youve finished cleaning, the mold will just re-grow from within these tiny crevices.

Another alternative to removing mold from wood is to get the old wood removed and replaced. In some cases, removing and replacing wood may take less time and work than cleaning large or difficult surfaces.

How Does Vinegar Kill Black Mold

Housekeeping Tips : How Do You Clean Mold From Wood Furniture?

White vinegar is the most preferred vinegar type to kill black mold. The product is acidic. Hence, it helps deodorize, disinfect, and clean up to 82% of mold species. You can use the product on both porous and nonporous surfaces.

If you use it safely, its offensive odor will go away in no time. But, of course, it would help if you had a spray bottle to pour the dilute white vinegar. Besides, dont think of diluting the vinegar with water since it contains only 20% acetic acid. Thus water will make it less effective.

With undiluted vinegar in the spray bottle, spray it over the affected area and give it at least an hour to work effectively. After this, wipe off the area using clean water, then give it some time to dry completely.

You should also note that any smell will clear off within a few hours.
