What are the disadvantages to using bleach (sodium hypochlorite)?
Bleach is inactivated by the presence of organic matter, e.g. blood. Bleach has a very strong odor and the mixing of chlorine and ammonia containing cleaning agents emits a highly toxic gas. Concentrations of bleach stronger than 1:100 are corrosive to metals. Bleach has a short efficacy life in liquid form and is sensitive to heat and sunlight.
