How To Use Bleach To Clean Mold

If You Have Mold In Your Home

How to remove and kill mold – Bleach vs vinegar

Mold can look like spots. It can be many different colors, and it can smell musty. If you see or smell mold, you should remove it. You do not need to know the type of mold.

If mold is growing in your home, you need to clean up the mold and fix the moisture problem. Mold can be removed from hard surfaces with household products, soap and water, or a bleach solution of no more than 1 cup of household laundry bleach in 1 gallon of water.

Bleach Is Ineffective In The Long Run

In the long run, bleach only helps you mask the mold for a short period. After you have applied bleach to a porous surface, the molds dark green color is removed, and your wall returns to its bright colors. However, the roots of the molds which have reached deep into the insides continue to grow. Also, bleach does not stop harmful mold spores from spreading within the house.

In the long run, you should call an expert to look into any mold problem you have. Cleaning mold is not enough to eliminate their harmful effects because, even when molds are dead, they can still produce toxic spores. Molds have to be removed entirely, and there are different procedures for doing this depending on the type of surface on which the mold has occurred. Air quality also needs to be returned to healthy levels. To achieve these, you should let a certified mold remediation specialist handle any mold problem you have in your home.

How To Prevent Mold

Prevent the growth of mold through the following methods:

  • Stop leaks that cause dampness on surfaces. Stopping leaks requires checking around windows frames, roofs, gutters etc., as well as ensuring pipes are joined properly with glue and other adhesives.
  • Keep the building ventilated by keeping the windows open and using fans to circulate the air in the building.
  • Keep surfaces dry and clean. For instance, users can place a dehumidifier in the basement or laundry room. Keep surfaces dry means keeping humidity levels below 50%.
  • Carpeting should not be placed in locations of your house that may get wet like the kitchen or bathrooms. Always dry rugs as soon as they get wet. If already infested with mold, throw them away.
  • It is also important not to use too many chemicals on floors as they might damage walls and paintwork that are damp from water leakage.
  • Clear and repair any gutters and downspouts to ensure water from the rain flows away from the walls.

If an area has already been contaminated by mold spores, it will be more difficult to prevent future outbreaks from occurring if there are still moisture problems within the house itself.

Still, the best way to remove mold is to call for a mold remediation expert who will assess the source of the mold, the extent of its growth then kills and prevents its regrowth. Clorox can kill mold but its not as effective as what a mold remediation expert will do.

    Should I use BLEACH to clean MOLD? | AdvantaClean of Charlotte

    Experts advise that you should never use bleach to clean mold, whether on a porous or non-porous surface. There are many reasons for this and mainly because, using bleach to treat or clean mold can jeopardize your health.

    Common household bleach is not necessarily toxic, but prolonged exposure to bleach can be very harmful to humans. When in the gaseous state, chlorine bleach produces a byproduct called dioxin, recognized as a cancer-causing compound. Hence, inhaling bleach is dangerous.

    In addition to this, mixing chlorine bleach with ammonia, drain cleaners, cleansers, or any other similar chemical produces chlorine gas, which can be very harmful to health. Exposure to chlorine gas can cause a burning sensation on the skin, eyes, and nostrils. It can also negatively affect the lungs or cause breathing anomalies, mostly when used around individuals with a lung condition such as asthma.

    To stress the potential harm of using bleach to kill mold, the the CDC advises against handling bleach without wearing complete personal protective gear. This includes an N95 respirator to prevent you from inhaling harmful gas, goggles, and protective gloves.

    In essence, using bleach to kill mold can cause you even more harm than the mold you are trying to kill.

    Bleach Can Contribute To Further Mold Growth

    Bleach is made up of about 90 percent water. Moreover, since molds thrive with moisture, spraying bleach on mold can contribute to further mold growth, especially on porous surfaces.

    Once you apply bleach to mold on a porous surface, the chlorine content of the beach dries up almost immediately, leaving behind the water content to be absorbed into the wood or any other absorbent material. The water travels down to the root of the mold and helps it thrive. This is why mold problems often become worse a few days after bleach is applied.

    Applying bleach on mold may even cause mold to grow in surrounding areas that were previously unaffected.

    How Bleach Works: Information About Disinfectants & Contamination Cleanup Procedures


    How does bleach remove stains?

    Household bleach is a mixture of sodium hypochlorite and mostly water .

    It’s the sodium hypochlorite that’s the active ingredient in bleach. Bleach is an oxidizing and a bleaching agent and a disinfectant. – Grant and Hackh’s Chemical Dictionary, 5th ed.

    The chemical formula for sodium hypochlorite is NaClO – or sodium , Chlorine and Oxygen . In NaClO the chlorie atoms are very reactive, snagging electrons from other nearby molecules. Nearby hydrocarbons that comprise organic materials and stains give up electrons to the chlorine while the oxygen and chloride molecules in the bleach stick to the carbons.

    Those modified carbon molecules are changed by their new passenge molecules to become highly soluble in water. Water, then, can flush those molecules away – removing the stains. Because the stain particles, now water soluble and now washed away, are physically removed from their original spot, the stain material is actually “gone” – in a favorable reaction.

    How does bleach disinfect surfaces, materials, or water?

    Bleach is also a really good oxidizer. Its easily-freed oxygen molecule oxidizes molecules that comprise bacteria, fungal spores , other organic materials , and even viruses, or cells within those organisms, thus “killing” them.

    The effectiveness of bleaching anything depends on the concentration of bleach and its exposure time. Higher concentrations and longer exposure increase the “kill rate” of bleach when attacking organisms.

    Dont Take My Word For It

    A simple study was conducted by the University of Oregon State. One of the purposes of the study was to examine if bleach can prevent or remove mold growth from Douglas-fir Lumber. The study found that While bleach is often recommended for remediation of surface mold on wood, our results illustrate that the treatment does not eliminate the surface microflora. As a result, an important component of remediation must be drying to moisture levels below 20 percent . In the absence of drying, some fungi clearly survive the treatment and may re-colonize the surface. You can check out the full study here.
