How To Remove Moldy Drywall: Get Rid of Mold

Vinegar is surprisingly effective on mold thanks to its acidic chemical makeup. As the product of fermented ethanol and acetic acid bacteria, it has a natural pH of roughly 2.5. This level of pH is very mild but strong enough to kill mold spores without driving them further into the porous surfaces theyre growing on. Not only does vinegar have anti fungal properties, its also been shown to be a great antibacterial cleaner as well, so using it can leave your household surfaces sanitized in the end.

The type of vinegar you choose to get rid of mold is extremely important distilled white vinegar is usually the most effective choice due to its lack of sugar or other ingredients. Alternatives like wine vinegar or apple cider vinegar might get the job done, but the sugar they contain is something mold spores can feed on, which increases the risk of the outbreak returning.

  • 1Keep the room well ventilated. To remove mold, you may need to work with chemical cleaners. Many of these cleaners can be harmful if inhaled and, as a result, you should keep the doors and windows open as you work. Never direct a fan of any kind into the room or you will absolutely spread the spores everywhere! A fan may be placed in windows facing outward to push bad air outdoors. You should seal off doors with plastic to avoid spreading the mold spores in other areas of the house.XTrustworthy SourceUnited States Environmental Protection AgencyIndependent U.S. government agency responsible for promoting safe environmental practicesGo to source
  • 2Protect the surrounding area. To prevent potential damage that could result if you accidentally spill chemicals or cleaners, protect anything that you do not plan on working with directly. Remove furniture and decorations to the other side of the room or out of the room completely. Cover the floor with newsprint or plastic drop cloth and tape the coverings taped in place. Keep an old rag on hand to catch any spills as you notice them.Advertisement
  • 3Choose a cleaning agent. Cleaning agents range from mild to potent and include both natural and chemical alternatives. If you have small children or pets in your home, you may want to consider a milder, natural solution over a powerful chemical one. If you have a more advanced mold problem, a stronger chemical may be necessary.
  • Why Can’t Moldy Drywall Be Cleaned

    It is very difficult, usually impossible, to adequately remove mold from porous materials, and that includes drywall. Why? Well, porous materials aren’t entirely solid, even if they appear solid to the naked eye. Materials like drywall have very tiny holes, or pores, in them, much like the pores in your skin. Microscopic mold spores can remain unseen in the pores of the drywall, even when the drywall appears free of mold. It’s similar to the way dirt or oil can be trapped in the pores of your skin, even if you don’t see it.

    Much like how dirt or oil trapped unseen in the pores of your skin can lead to acne or other skin problems, unseen mold trapped in the pores of drywall can grow and spread and can also cause health problems. Since there is no effective way to remove mold from the pores of the drywall, the affected drywall must be removed and replaced.

When airborne water vapor hits a cold surface and turns into a liquid, mold may grow on your cellar or exterior walls. Because restrooms and laundry rooms are often damp, mold may flourish there.

    You can frequently see mold and mildew coexisting on grout. The walls and ceiling next to humidifiers and any room with a hot tub or jacuzzi are other places that are humid and prone to mold.

    Vinegar Also Kills Mold On Non

    Vinegar is also effective for removing mold from hard, non-porous surfaces. Although the leading surface disinfectant, household chlorine bleach, is effective for this application, it is harsh and toxic.

    A solution that consists of a 5% to 6% concentration of acetic acid in water is much milder and may be less likely to irritate the skin, eyes or mucous membranes of the person who is attempting to clean up the mold. Vinegar may also be less likely to damage or discolor walls than strong alkaline bleach solutions.

    When you apply a solution of bleach diluted in water to mold on hard, non-porous surfaces, this treatment should be sufficient to eliminate mold. In the case of tiled walls, bleach will not penetrate into porous grout between tiles but can still wear down sealant. Vinegar can be a better choice for walls that combine non-porous tiles and porous grout.

    If you are cleaning a non-porous surface, it may not be necessary to wait as long as two hours before scrubbing or wiping down a moldy wall. Within five minutes of applying full-strength or diluted vinegar, it should become easier to remove mold from walls.
