Mold spores can adhere to tiny particles of dust and dirt on a mirror. A clean mirror isn't conducive to mold growth because the surface isn't porous. But dust and dirt present on the surface of your mirror provide the fungus with a place to grow. To keep your mirror mold-free, you must keep it clean. You can get mold off your mirror with common household supplies, and enjoy your reflection without ugly mold stains ruining the view.

Things You'll Need

  • Spray bottle
  • Paper towels
  • Bucket
  • 2 tablespoons ammonia
  • Clean cloths

Spritz water on the mirror with a spray bottle to prevent mold spores from becoming airborne. Wipe the mold spores off with a paper towel. Discard the paper towel in a sealed trash can.

Fill a bucket with 1 gallon of warm water. Add 2 tablespoons of ammonia.

Dip a clean cloth in the diluted ammonia solution. Wring out the cloth to remove excess moisture.

Wipe the surface of the mirror with the ammonia-dampened cloth. Rinse the cloth as mold stains lift off the mirror. Add more ammonia solution and continue to clean the mirror to remove remaining mold spores and stains.

Dry the mirror with another cloth. Buff the glass to a shine with a second cloth, if desired.

Tips & Warnings

  • Substitute full-strength vinegar or rubbing alcohol to kill mold on the mirror and clean the glass.
  • Regulate excessive humidity in the home with a dehumidifier.
  • Repeat mold stain removal methods with a light touch instead of scrubbing the glass too hard to avoid breakage.
