Using bleach to kill mold is not recommended when the mold is on any porous surface, like wood, for several reasons. Bleach can be harmful to health, especially when inhaled, as it can produce toxic gases like chlorine gas[1]. Additionally, bleach is ineffective in the long run as it only masks mold temporarily and can contribute to further mold growth on porous surfaces[2]. Furthermore, bleach does not penetrate porous materials effectively to kill mold at its roots, leading to regrowth and potentially worsening the mold problem over time[3].
In essence, while bleach may remove surface mold temporarily on non-porous surfaces, it is not a long-term solution for mold remediation and can pose health risks and contribute to the growth of mold on porous surfaces. It is advisable to explore safer alternatives. White vinegar, baking soda, and undiluted 3% hydrogen peroxide can each be used for cleaning mold more effectively without the drawbacks associated with bleach[3]. Some products such as Concrobium will form a protective film on a porus surfaces to prevent mold from reappearing.
The active ingredients in Concrobium Mold Control are Sodium Carbonate, Trisodium Phosphate, and Water. While Sodium Carbonate is the listed active ingredient on the label, these two additional ingredients, when combined with Sodium Carbonate and water, create a patented tri-salt polymer that effectively eliminates and prevents mold
Concrobium effectively eliminates and prevents mold growth on various surfaces by forming an invisible barrier over surfaces to repel new spores and prevent them from taking root[14]. This product is billed as containing no harmful chemicals like bleach, ammonia, or VOCs, making it safe for use in areas like kitchens and showers[11][12]. Concrobium works by hardening over moldy surfaces, physically crushing the mold micro-organism underneath, and eliminating musty odors[15]. It is suitable for use on a wide range of surfaces such as drywall, wood, concrete, metal, fabric, and more[13][15]. Additionally, it is non-toxic and safe for septic systems. It can be used in various settings including homes, businesses, institutions, and even vehicles like cars and boats[15].
When using it, there are some precautions to consider:
1. Avoid Over-Application: Applying too much Concrobium can lead to residue formation as the product dries. If this happens, simply wipe away the residue with a dampened cloth[11].
2. Wear a Mask in Heavy Mold Growth Areas: While Concrobium does not contain harmful chemicals like VOCs, wearing a mask in areas with heavy mold growth can limit inhalation of mold spores[11].
3. Proper Coverage: Ensure that the surface is lightly wetted for the product to be effective. The coverage will depend on surface absorbency and application method[11].
4. Avoid Mixing with Other Substances: Using Concrobium as recommended without adding any other substances ensures its efficacy[11].
5. Application in Specific Areas: Concrobium Mold Control can be safely used in kitchens and showers due to its non-toxic nature and lack of harmful chemicals like bleach or ammonia[11].
6. No Need for Evacuation: Unlike some harsh chemicals, Concrobium does not require evacuation of the area during use[11].
These precautions help ensure safe and effective use for mold remediation and prevention[16].
