What is the difference between Mold and Mildew?
Mold and mildew may have similar characteristics but they are different kinds of fungi.
Mold is a type of fungus that produces growth on moist and decaying surfaces. It can grow on leather, clothing, ceilings and food.
Mildew also grows on moist surfaces. It is generally found in bathrooms and bathtub grout and sometimes smooth stone window sills. It generally stains the surface however sometimes it can gray or white fuzzy substance. If it stains the area like a grout area it is generally not going to get into the air. A recent swab test of a bathroom grout reveal zero for molds on the lab report. If it does aerosolize then it can act as an inhalation irritant just like pollen or dust.
