What Kills Black Mold On Wood

What Is The Best Way To Clean Mold From Wood

How To Remove Toxic Black Mold From Wood!

When cleaning mold off wood, there are several solutions you can use depending on their strength, availability, and level of penetration of the mold into the woods surface.

Below are some of the best cleaning solutions to use on the mold with the respective procedures to get the best possible results.

  • Water and detergent
  • Perhaps the simplest way of cleaning mold from wood is using water and detergent. This method is an excellent option for cases where you are sure that the mold has not penetrated the wood surface. To use this solution:

    • Prepare a soapy solution with water and detergent.
    • Spray the moldy surface and use a soft-bristled brush to scrub the mold away. You can also dip the brush into soapy water.
    • Dry the wood surface with a towel to minimize the chances of a recurrence.

    If soap and water prove unsuccessful, you can use a baking soda solution.

    To use baking soda in cleaning mold, mix the baking soda and water to create a solution that you will spray over the surface covered in mold. Use a soft-bristled brush to scrub the mold. Keep spraying the baking soda solution if you feel the area needs extra disinfecting.

    White vinegaris one of the most popular options when removing mold. The mild acid found in vinegar is excellent for removing mold and preventing future recurrences. When using vinegar, go for the distilled white vinegar, which typically has around 5% acidity. To clean mold with distilled white vinegar:

  • Chlorine bleach
  • Hydrogen peroxide
  • How Frequently Do You Need The Mold Inspection

    Now that you know the meaning of mold inspection and testing, you need to avail yourself of these services on a regular basis for the mold check. You may call upon these services once or twice a year based on the risk of mold growth in the surroundings you reside. Early detection can help in taking the right measures and increase the effectiveness of the solutions.

    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.

    Where Not To Use Hydrogen Peroxide To Remove Mold And Mildew

    As we mentioned, hydrogen peroxide is unlikely to inhibit mold growth on porous surfaces like fabrics and wood. If you notice mold on bath rugs, wooden walls, or other porous surfaces, the object or surface will need to be safely discarded according to your local disposal rules.

    Hydrogen peroxide has the potential to bleach some types of natural fabrics like wool.

    Hydrogen peroxide is generally safe on solid surfaces and even most synthetic fabrics. To avoid accidental bleaching, make sure to clean off all the hydrogen peroxide once you finish cleaning the mold.

    When cleaning mold in your home, its a good idea to wear protective gloves, goggles, and a mask to prevent coming into contact with mold spores.

    Heres how you can clean mold from solid surfaces using hydrogen peroxide:

  • Pour 3-percent hydrogen peroxide into a spray bottle. Spray it onto the moldy surface until the area is completely covered.
  • Let it sit for about 10 minutes or until the hydrogen peroxide stops bubbling.
  • Scrub off the mold and hydrogen peroxide with a rag or soft brush. Start by scrubbing gently to avoid damaging the surface beneath the mold and slowly scrub harder as needed.
  • When finished, wipe the surface dry with a clean cloth or rag.
  • Repeat if necessary.
  • Hydrogen peroxide is just one of many household ingredients you can use to clean mold. Using vinegar is another effective way to clean mold in your home.

    However, its important not to mix hydrogen peroxide and vinegar together.

    Understanding The Different Types Of Mold

    The three most common types of mold can be identified by their color black, white, and green.

    Black Mold

    Many types of mold are black and harmless. However, one of the most dangerous types of black mold is Stachybotrys chartarum.

    Because it releases mycotoxins, exposure to this black mold can cause serious health issues. This includes respiratory problems, headaches, and more .

    Black mold needs more moisture than other types of mold in order to grow. As a result, its more likely to be found in damp places or in areas where theres been a flood or water leak .

    Unfortunately, this type of mold has deeper roots than the other types of mold. Naturally, this makes it harder to get rid of, especially if it has infested porous surfaces like wood.

    White Mold

    White mold has a powdery, stringy appearance and is not toxic. However, a moldy environment within the home can still cause health issues for you and your family.

    White mold grows on organic materials, such as wood, fabric, food, and carpet. Mold growth on a wooden structure can cause rot and destroy it if not dealt with.

    Green Mold

    The term green mold applies to various species and usually has a soft and fuzzy texture. This type of mold grows on spoiled food like bread and fruit. Youll also find it in areas of your home with a water problem.

    Will Vinegar Kill Mold

    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.

    Cleaning Mold With Bleach

    Always use protective gear when cleaning mold.

    According to conventional wisdom, bleach kills mold growth. However, this is somewhat of a myth as bleach only kills the mold on the surface without affecting the membrane underneath. You need to kill and remove this underlying membrane to effectively remove the mold growth and prevent it from returning. Bleach cleaners cannot kill this membrane because its chemical structure prevents it from penetrating porous surfaces. This causes the mold membranes to move deeper into the affected surface to hide from the bleach. You should only use bleach to remove small amounts of mold that have formed on non-porous surfaces.

    Another problem with using bleach is that it can actually multiply the mold growth. When bleach is introduced to mold colonies, the mold recognizes the bleach as a threat and reacts. Mold can actually use bleach as a food source once it has been exposed which will cause the mold to grow back faster and stronger. Even the EPA advises against using bleach for removing mold. Fortunately, there is another household item that can kill mold.

    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.

    Poor Placement Of Fans

    Poor placement of fans can be another factor that leads to black mold growth. Often, kitchen, dryer and bathroom vents may be opening up into an area of your house instead of outside. This allows damp to build up inside of your house which can lead to black mold growth. One of the most common causes of black mould growths in homes is poor ventilation. Additionally, a large variety of building materials actually provide the perfect nutrients to aid black mold growth, which would explain why black mold on wood is extremely common.

    How Do You Use Vinegar To Clean Mold

    To safely and effectively clean a small area of mold, ServiceMaster advises the following:

  • Add full-strength white distilled vinegar to a spray bottle and spray it on the mold.
  • Let it sit for at least an hour before wiping away mold.
  • If you need follow-up scrubbing, combine one teaspoon baking soda with two cups of water. Pour it into a spray bottle, shake and spray it onto the mold. Scrub with a brush or scouring pad.
  • Rinse with warm water, then spray again with the vinegar and let it dry.
  • To protect yourself from mold and its spores, wear gloves, a mask and goggles. Gloves also prevent any skin irritation from the vinegar.

    All types of vinegar are acidic, and acids can slowly break down the structure of mold and kill it. Distilled white vinegar is non-toxic but acts much more slowly than chlorine bleach or hydrogen peroxide. While it will kill the mold, the discoloration and stains may remain and require additional scrubbing with a household cleaner.

    Distilled white vinegar can be used safely on most porous and non-porous surfaces. Pour undiluted white vinegar into a spray bottle and spray onto the moldy surface. Let it work for an hour.

    Tip On How To Get Rid Of Mold On Wood Using Bleach

    In extreme cases or the case of untreated wood, mold can penetrate the wood and make itself at home. If it penetrates, you will need a stronger cleaner something more than just soap and water to clean outdoor wood furniture.

    You can make up as much or as little of this powerful cleaning solution as you would like, as long as you keep the parts the same. In a big bucket mix together all three ingredients. Apply the bleach solution to the wood using a stiff-bristled brush or a scrubbing sponge. After scrubbing the wood, allow it to air-dry.

    Use dehumidifiers and fans to help speed up the drying process, but allow the wood to dry for at least three days. Inspect the wood for any signs of mold, and look and smell the wood. If mold is still present, your best mold remediation is to clean with the bleach solution again.

    Once you know its is no longer present, seal the wood with a primer or pigmented shellac from your local hardware stores. If mold is still present or you notice mold stains, your only other option is to sand the wood. Using sandpaper to sand down the wood allows you to reach the mold or stains that are deep inside.

    You dont want to do a quick sanding instead, slowly sand the wood until either the mold or the mold stains are gone. Once gone, you should stain, paint, or treat the wood to help prevent future problems.

    Stopping Mold From Reappearing

    At the start of this article, I mentioned that mold spores are everywhere, and theres nothing we can do to prevent their access to our homes. However, they need an environment to support the spores growing into the visible mold. If we can deny them that environment, we can stay mold-free.

    • Mold thrives in damp, warm, still environments. Thats why bathrooms and basements are prone to mold growth. Install fans or ensure adequate airflow to dry any steam, condensation, or humidity. If the moisture doesnt have time to sit, mold is less likely to form.
    • Consider protecting the surface with either a mold-inhibiting paint or a polyurethane coating. While mold will form on any surface, it is easier to remove from a smooth surface finish than from a porous surface like bare wood. You can purchase waterproof coatings for basements and masonry or mold-resistant paints.
    • If you have furniture with a natural finish, beeswax polishes are a great natural product. They have anti-fungal and anti-microbial properties and form a layer between the wood and moisture.
    • Dust, vacuum, and wipe all organic surfaces regularly. Regular cleaning will reduce the volume of mold spores over time and reduce the chances of mold gaining a foothold.
    • If the mold gets into fabrics and carpets, it can be extremely difficult, if not impossible, to remove. You can launder moldy clothes in a borax solution, but carpet tiles, carpet, and drywall may need to be replaced.
