What Is Mildew?

Mildew is typically flat and powdery, white, gray, or yellow, and grows on surfaces rather than penetrating materials. Common on shower walls and windowsills.

What Is Mold?

Mold is fuzzy, can be many colors including black, green, and white, and penetrates porous materials. It can cause structural damage and serious health effects.

Which Is More Dangerous?

Both cause respiratory irritation but mold carries greater health risks. Any growth that has penetrated building materials warrants professional assessment.

DIY for Surface Mildew

Surface mildew on non-porous surfaces can often be cleaned with bleach solution. If it returns quickly, a persistent moisture problem needs to be fixed.
