According to the CDC website, exposure to mold indoors has been linked to upper respiratory tract symptoms, cough and wheeze in otherwise healthy adults and children, and asthma symptoms in people with asthma. It has also been linked to hypersensitivity pneumonitis in individuals susceptible to that condition. For indoor mold cleanup, we would recommend a product called Concrobium. There are lots of benefits to Concrobium. It's safe for any surface, including fabric. It leaves a protective barrier when it dries. Bleach doesn't do that, and bleach is also not fabric-safe. Bleach will kill mold spores on application, but unlike Concrobium, it doesn't offer any ongoing protection.
