Bleach loses 50% of its effectiveness after 3 months and has a short shelf life. It is not effective at penetrating porous surfaces like wood or concrete so cannot kill mold at its root. When used, bleach releases harmful gases that can cause issues like pulmonary embolism in humans. It also degrades quickly in the presence of water which can encourage further mold growth. Contact with bleach can cause skin irritation and burns. Bleach is not registered by the EPA as an approved disinfectant for killing mold.

1. BLEACHThe Ugly Truth
Studies have shown that bleach loses 50%
of its effectiveness over a period of 3
months. The end result is a shorter shelf-
life.
LOSES EFFICACY RAPIDLY
The chemical properties of bleach prevents
it from effectively penetrating porous
surfaces such as wood, sheet rock, grout,
and concrete.
CANT KILL THE ROOT OF MOLD
Chlorine bleach releases gasses that are
known to be harmful to animal and plant
life. One of the known causes in humans is
pulmonary embolism.
EMITS HARMFUL GASES

Bleach decomposes in the presence of
water, and the remaining water encourages
mold growth.
DEGRADES QUICKLY
Skin contact will produce caustic irritation
or burns due to defatting and saponification
of skin oils and destruction of tissue.
CAUSES SKIN IRRITATION
Chlorine Bleach is NOT registered with the
EPA as a disinfectant to kill mold.
