Researchers at National Jewish Medical and Research Center have demonstrated that dilute bleach not only kills common household mold, but may also neutralize the mold allergens that cause most mold-related health complaints. The study, published in the Journal of Allergy and Clinical Immunology, is the first to test the effect on allergic individuals of mold spores treated with common household bleach. The researchers found that, under laboratory conditions, treating mold with bleach lowered allergic reactions to the mold in allergic patients. However, in order to assure that the bleach solutions will function similarly under actual field conditions, additional experiments will need to be conducted. Their study and findings are further discussed in this article.
