A clogged bathroom fan stops removing moisture – allowing mold to grow.

  1. Turn off the fan at the switch or breaker.
  2. Pull down the cover (most have spring clips or snap off).
  3. Wash the cover in warm soapy water. Dry completely.
  4. Vacuum the fan blades and motor housing with a brush attachment.
  5. Wipe accessible surfaces with a damp cloth.
  6. Reattach the dry cover.

Do this every 6 months. A labored sound or visible dust caking means it may need replacement.
