    Does Bleach Kill Mold?

    Yes, bleach is a potent biocide that can be used to kill mold.

    The active ingredient in bleach, sodium hypochlorite, reacts with water to form hypochlorous acid, which kills mold by denaturing proteins, inactivating enzymes, disrupting nucleic acids, and destroying other cellular components.

    Because bleach requires direct contact to kill mold, its most effective at killing mold on the surface of nonporous surfaces like tiles and sinks. Its not as effective at killing mold on porous materials , which absorb moisture and allow mold to penetrate underneath the surface.

    When using bleach, the CDC recommends using a diluted solution of no more than 1 cup of household bleach mixed in with 1 gallon of water. Never mix bleach with ammonia-based cleaners, which can react to produce toxic fumes.

  • Apply the diluted bleach solution to the moldy surface
  • Let it sit for 15 minutes
  • Scrub off the mold
  • Dry the surface thoroughly

    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 To Clean And Kill Mold With Bleach

    • Use a ratio of one cup of bleach per gallon of water .
    • Apply the solution to nonporous surfaces with mold growth using a spray bottle or a bucket and a sponge or cloth.
    • No need to rinse the surface afterward, unless it is used for food prep or a surface which may be touched by small children or pets.

    How Does The Mold Grow And Reproduce

    Molds are fungi, simple microscopicorganisms that thrive anywhere with a moist environment. They grow in the formof multicellular strands known as hyphae.They reproduce by the production of large numbers of small spores which maycontain a nucleus or be multinucleate. These spores are comparable to the seedsof a plant, though they are much smaller than seeds or even pollen grains. Thesmall size makes them easy to disperse through the air and water. They can also disperse long distances byclinging on the clothing and fur. They will only start to grow once they landin an environment with suitable temperature, food, water and oxygen.

    What Is The Recommended Way To Destroy Mold

    Back in the day I’ve heard that bleach is a good way to kill mold. The other day a home inspector suggested that Dawn dish soap actually works much better than bleach. I’ve heard from another home inspector to use the store-bought mold killer.

    Does anyone know what really works and what doesn’t for a DIYer?

    • Bleach will react and become inert after a short period of time and the mold can re-establish. Detergent will stick around a lot longer. Other mold treatments include Sodium Carbonate, TSP, and other salts that make it hard for mold to re-establish especially if things are kept relatively dry.May 2, 2015 at 13:35

    Bleach, when used carefully, may be effective at killing surface mold.

    How do you get those hyphae out of the wood or other material? You need a surfactants.

    Surfactants serve the purpose of significantly lowering the surface tension of water to allow a cleaning solution to penetrate porous surfaces –KleanPros

    What’s an example of a Surfactant? Dishwashing soap.

    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.
