Debunking The Myths About The Effect Of Bleach On Mold

Last Updated on November 30, 2016

The idea that bleach can actually get rid of mold is entirely wrong. It is actually a premise that has been disseminated by bleach companies as well as DIY communities.  The assumption is that mold can be removed by simply spraying bleach on the affected area. Scrubbing then follows to remove the mold from the surface. In light of that, you need to understand that scrubbing a particular surface clean only gets rid of the surface mold. This means that it is only going to worsen the mold situation.

Interaction between mold and bleach


When you spray bleach on mold, it will react as if it were under an attack. This implies that as you spray down the bleach, mold will actually be shooting off spores for protection. Now as you unknowingly wipe the surface, you will be spreading the spores further, thus worsening the situation. If the rag used to wipe the surface with mold is used on other areas of the house, it may lead to further spread of the mold to areas that were not even affected at all. The interaction between mold and bleaches in this regard clearly shows the effects of spraying and wiping off mold on surfaces.

Bleach component

Molds will do well in a place with a good amount of moisture. Well, the sad news is that bleach actually has water as a component. Furthermore, the chemicals present in the bleach (inclusive of chlorine) do not effectively penetrate through the porous spots of wood or sheetrock. Since the roots of the molds are usually at the porous spots, it makes it hard to completely get rid of mold. In addition, the constituents of bleach make it highly acidic. This is actually a menace to the integrity of porous materials.

Effect of bleach on home construction materials

As mentioned earlier, bleach is highly acidic and as such, it can easily wreak havoc on home construction materials. For instance, spraying bleach on dry wall actually damages its fabrics and weakens its integrity. As the bleach ruins the integrity of home construction materials, it also causes further spread of mold. In the case of the drywall, its destruction by use of bleach simply causes mold to easily spread to other unaffected areas in the house. The worst part is that this is not usually noticeable until sometime later. Now you do not want to be taken by surprise.

Presence of mold

Bleach sort of creates an illusion that the mold is gone. The truth of the matter is that once you spray bleach on the wall or any other surface, you will no longer be able to see mold. However, it still remains present on the wall though you cannot see it. The deep roots of mold allow it to penetrate to the outer surface and get sustenance even after spraying bleach on the inner surface. Essentially, bleach is not the right solution for removing mold roots in an affected area.  You need to consult professionals for mold remediation in Toronto to be in a position to determine the right approaches for complete annihilation of mold. Therefore, you can start off with finding a certified mold removal company. These companies follow certain protocols that ensure effective removal of mold.

Therefore, you should not make the mistake of assuming that bleach is the right solution for mold removal. It may make things look better but this will only be temporary as the situation will get worse by the day. You can always inquire about the most effective ways of mold inspection and the recommended solutions. In most cases, hiring mold removal contractors makes the whole situation easy to handle as they have the knowledge and equipment to assess and handle any kind of mold threat.
