It is not uncommon to find mold growing in various areas of your bathroom. Mold requires a damp, dark and humid location to grow and thrive, which makes bathrooms the perfect breeding ground for mold and its spores. If mold is not dealt with in a timely manner, it can eat away at the item and deteriorate it beyond repair. Mold growing on your ceiling could be a sign of a ventilation problem which you should look into after the mold has been removed.

Things You'll Need

  • Water
  • TSP
  • 2 Buckets or containers
  • 3 Sponges or cloths
  • Bleach
  • Stain killing primer
  • Mildew resistant top coat

Video of the Day

Combine 2 cups of warm water with ¼ cup of TSP—trisodium phosphate—in a bucket or container.

Saturate a sponge in the solution and wring out the excess mixture.

Scrub the bathroom ceiling with the sponge. When the sponge becomes dirty, resaturate it in the solution. Continue scrubbing until all mold is gone.

Pour undiluted bleach in a small container. Submerge a sponge or white cloth in the bleach and wring out the excess liquid.

Wipe the bathroom ceiling with the sponge. Allow to sit for a few hours.

Dampen a clean cloth with cool water. Rinse the bathroom ceiling with the cloth.

Tips & Warnings

  • After the ceiling has dried, prime the bathroom ceiling with a stain killing primer and apply a mildew resistant top coat to prevent mold growth.
  • Wear rubber gloves when working with chemicals to prevent skin irritation.
