Where Is Mildew?

Mildew most commonly shows up as black, grey, or brown powdery substances or stains that develop on the surfaces of the paint on walls and ceilings, on caulk, and in cracks.

A mildew problem with paint typically shows up on walls and ceilings in locations that are subject to moisture, such as outdoor patios, bathrooms, kitchens, and areas with poor ventilation, including closets. 

It is important to determine the cause of the mildew, whether it be lack of ventilation, leaking pipes, water entering the house from outside, or another cause, and fix this issue.

Identify the Problem

The first thing to do if you discover a dark mark resembling mildew on painted walls or ceilings is to test to determine if it is mold or mildew.

Using household bleach, place a few drops on the suspect area and wait several minutes. After this time, if the spot has become lighter, it is mildew, and if it is darker or unchanged, it is mold.

A mold problem is more complicated than mildew, and may require professional help.
