“Perhaps the most misunderstood aspect of bleach when proposed as a cleaner or sanitizing agent is that its effectiveness is greatly reduced in the presence of organic material. To be a successful sanitizer, bleach must be used on clean materials and surfaces. This is why bleach products are used in the laundry after the wash cycle or in a commercial kitchen as a component in the third sink after the dishes have been washed and rinsed. The efficacy of bleach as a sanitizer is also compromised by heat and light. Despite the fact that the chlorine odor may linger for some time after use, bleach loses strength so quickly that it is not considered to have a residual effect that would prevent future bacterial or fungal growth.” Micheal Pinto CEO of Wonder Makers Environmental
One of the greatest invention thus far today has been the Internet. It has given everyone an equal opportunity to search and invest their time into any topic of interest. Unfortunately, this does allow for both good and bad information to be available for research. As we are barely getting into the scientific studies on mold and the effects of exposure, it is hard to gain valuable information.
In respect to mold, the internet is full of incorrect information! Bleach may have some impact on non porous materials such as bathroom glass, tile, or porcelain toilet but it is completely ineffective on porous materials.
“If you spray bleach all over your “black toxic mold” you won’t kill every single spore….To kill every single mold spore using bleach, for example, you’d have to use such a high concentration of disinfectant and you’d have to keep it on the surface for so long that more likely you’d damage the structure – and still miss some toxic spores.” Should we be trying to kill mold?
Bleach does not address the problem! Experienced Remediation specialists understand the most effective way to deal with mold is to first fix the source of moisture.
The next step is to set containment with plastics, tapes, and poles if necessary to secure the containment and block off any HVAC or areas for air movement.
Set up an AFD ( Air Filtration Device) to create negative pressure allowing to clean the air during air exchanges.
Then remove the materials under containment making sure to HEPA vacuum bags as they leave the containment. All occupants should be required to wear a full face mask with proper PPE attire.
Proper removal of mold contaminated materials like drywall, carpet, soft goods, insulation, and other porous materials is essential because mold has hyphae, which are basically roots that embed themselves in the material. This is the reason that bleach does not work. Bleach may kill some of the surface mold, but it will not be able to penetrate and kill the roots. The other reason bleach is a problem is that it is diluted with water. Spraying this is counter-productive because water is an essential ingredient mold needs to grow. Keep in mind, even if another biocide or fungicide is sprayed on the material, killing the roots, the material will still be contaminated with dead spores. The best course of action to permanently deal with a mold problem on porous materials is to properly dispose of the contaminated material.
