Envirocleanse-A (ECA) is a chlorine-based product that is effectively used as a disinfectant for water treatment. ECA has an equal efficacy as bleach, with none of the toxicity. The EPA has given ECA the lowest possible rating for toxicity. ECA is completely non-harmful to humans and other warm-blooded animals so there is no need to handle toxic chemicals and worry about handling, spilling, or leaking of those harsh chemicals. Kill microorganisms, destroy pathogenic organisms, and cut the spreading of waterborne illnesses with ECA.
