object to killing mold is
to kill mold at its “roots”.
Mold remediation involves the
need to disinfect wood and wood-based building materials, all of which are
porous materials. Thus, chlorine bleach should not be used in mold
remediation as confirmed by OSHA’s Mold Remediation/Clean Up Methods
guidelines. The use of bleach as a mold disinfectant is best left to kitchen
and bathroom countertops, tubs and shower glass, etc.
Chlorine Bleach does kill bacteria and kill viruses, but has not been proven
effective in killing molds on non-porous surfaces.
Bleach itself is 99% water. Water is
one of the main contributors of the growth of harmful bacteria and mold.
Current situations using bleach re-grew and regenerated mold and bacteria
twice the CFU counts than were originally found before bleaching, within a
short period of time. Bleach is an old method used for some bacteria and
mold. It is the only product people have known for years. The strains now
associated within Indoor Air quality issues are resistant to the methods our
grandmothers employed to clean-up mold.
What potential mold 'killing' power chlorine bleach might have, is
bleach sits in warehouses, on grocery store shelves or inside your home or
business 50% loss in killing power in just the first 90 days inside a never
opened jug or container. Chlorine constantly escapes through the plastic
walls of its containers.
ionic structure of bleach prevents Chlorine from penetrating into porous
materials such as drywall and wood
just stays on the outside surface, whereas mold has enzyme roots growing
inside the porous construction materials---however, the water content
penetrates and actually FEEDS the mold---this is why a few days later you
will notice darker, more concentrated mold growing (faster) on the bleached
Chlorine Bleach accelerates the deterioration of materials
and wears down the fibers of porous
Chlorine Bleach is NOT registered with the EPA as a disinfectant to kill
You can verify this important fact for
yourself when you are unable to find an EPA registration number for killing
mold on the label of any brand of chlorine bleach.
Chlorine bleach off gases for a period of time.
Chlorine off gassing can be harmful to
humans and animals. It has been known to cause pulmonary embolisms in low
resistant, and susceptible people.
Chlorine bleach will evaporate within a short period of time.
If the area is not dry when the bleach
evaporates, or moisture is still in the contaminated area (humidity, outside
air dampness), you could re- start the contamination process immediately and
to a greater degree.
Chlorine is a key component of DIOXIN.
One of the earliest findings of
dioxin's toxicity in animals was that it caused birth defects in mice at
very low levels. This finding led to dioxin being characterized as "one of
the most potent teratogenic environmental agents". The first evidence that
dioxin causes cancer came from several animal studies completed in the late
1970's. The most important of these, published in 1978 by a team of
scientists from Dow Chemical Company, led by Richard Kociba, found liver
cancer in rats exposed to very low levels of dioxin. This study helped
establish dioxin as one of the most potent animal carcinogens ever tested
and, together with the finding of birth defects in mice, led to the general
statement that dioxin is the "most toxic synthetic chemical known to man."
