Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases for three decades, one of the leading experts on pandemics in the U.S., and the good neighbor you’ve always wanted, dished out some very harsh words while speaking at the Senate Health, Education, Labor and Pensions Committee in Washington, D.C.

@Vina OkoThe good news is the color isn’t an indicator of the toxicity of a mold or mildewToxic molds can be a variety of colors and are a problem when the spores produce into the air and stop lungs from functioning.Most likely in a washer that is front loaded you are not dealing with something toxic.If you have a mold allergy use caution when cleaning.
