Killing Mold And The Bleach Myth
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.
The Internet is a great source of information, but unfortunately there are still websites that recommend bleach. Main stream online publications like the Huffington Post and even the CDC recommend that bleach can be used to kill mold.
Fortunately, the Occupational Safety and Health Administration and the Environmental Protection Agency no longer recommend the use of bleach because using chlorine bleach to kill mold is one of the worst things you can do.

Liquid household bleach has 5.25 to 8.25% of the active sodium hypochlorite ingredient. It also contains other secondary ingredients such as sodium hydroxide which is intended to keep the solution alkaline.
It is the sodium hypochlorite in bleach that denatures proteins in microorganisms that thrive on roofs. This ingredient is effective in killing algae, mildew, mold, fungi, bacteria, and viruses.
The Sodium hypochlorite becomes hypochlorous acid when it comes into contact with water. Hypochlorous acid is the active ingredient further that attacks proteins that make up the microorganisms leading to the destruction of the algea as well as other microorganisms on your roof shingles.

Does Not Work On Porous Materials
Bleach doesnt work well on porous materials such as drywall, carpeting and wood paneling among others. Bleachs chemical setup prevents it from soaking up into the material and killing mold from within or removing stains. Bleach can work well for non-porous surfaces because when applied, it wont seep into anything else but its intended area.
With bleach being made up of 90% water and 10% chlorine, the chlorine will evaporate leaving the water behind. This further encourages the remaining mold to regrow.
As stated by the Environmental Protection Agency , always call for a professional mold cleaner if the mold covers more 10 square feet or more. Mold remediation should help do away with the mold and mildew permanently.
Using Bleach For Cleaning Mold
