In my previous post, where I discussed about mold removal products, I mentioned about using bleach to kill mold. Today I will talk about the effectiveness of bleach as a mold removal product, its usage and limitations in killing mold. To learn about other mold removal products, you may refer to my previous posts.
Bleach is the product we have known for years to be good at killing bacteria and viruses. Some believe bleach can kill mold as well. Yes, bleach is a mold killer, but that’s limited to molds grow on non-porous materials such as counter-tops, tiles, bathroom, shower glass, tubs, etc. When dealing with mold infection on non-porous surfaces, you can use a mixture of less than a cup of bleach to one gallon of water to effectively disinfect and kill molds.
However, the use of bleach to kill molds on porous materials is not recommended for the fact that bleach contains 99% of water. When bleach is used to clean and disinfect porous materials like wood and drywall, the Iodin structure of bleach prevents Chlorine from soaking into the materials to kill the roots of molds. While the water element of bleach penetrates through the surfaces and feed the roots. Therefore remediating porous materials with bleach is said to accelerate mold growth rather than stopping and killing it.
Bleach is corrosive. It releases harmful fumes that can cause serious health problems. When bleach is used as mold removal product, make sure you follow proper safety measures to protect yourself from inhaling the toxic fumes.
In conclusion, bleach can be used as mold removal product for non-porous surfaces like glass, tiles, tubs, counter-top and etc. Do not ever use bleach to kill mold on porous materials like wood and drywall. It expedites mold infestation due to the water content of bleach. Remember to put on protective gears whenever dealing with any mold removal product such as bleach. Do not mix bleach with ammonia, as this will create toxic fumes. Bleach is not registered with EPA as a mold removal product. Thus the effectiveness of killing mold with bleach is not proven.
