The Difference Between Mold and Mildew

You may or may not be aware of the negative health impacts of mold. Caused by bacterial growth and mycotoxins, mold can present significant risks to your family’s health. Knowing the distinctions between mold and mildew is essential to determining why your bathroom smells bad.

Mold usually grows in clumps of spores that appear as yellow, black, brown, and green spots. These spots also grow around and through porous materials in your bathroom, which remain unchanged by regular cleaning. Mildew, on the other hand, grows on bathroom surfaces, responds well to normal cleaning supplies, and poses fewer health risks to your family.
