How to Kill Mold in the Garage


Garages are generally an ideal environment for mold to grow since they are not insulated from moisture and heat. Once you spot mold in your garage, call your landlord and have it removed if you are renting. If you are a homeowner, you can remove mold from your garage on your own. Safety should be observed when removing mold, as it is a health hazard.

Things You'll Need

  • Gloves
  • Goggles
  • Painter's mask
  • Ammonia-free detergent
  • Bleach
  • Distilled water
  • Bucket
  • Spray bottle
  • Stiff-bristled brush
  • Fan
  • Dehumidifier
  • Put on gloves, goggles and a painter's mask. Open the garage door and windows, if applicable, to provide the best ventilation possible.

  • Mix together 5 parts bleach with 1 part ammonia-free detergent and 20 parts distilled water in a bucket. Use distilled water, as it is free of any bacteria and other impurities. Fill a spray bottle with distilled water as well.

  • Mist the mold with the spray bottle to make it moist and keep spores from spreading as you kill it with the solution. Dip a stiff-bristled brush into the bucket and scrub the mold away from the garage. If the mold cannot be taken up with this solution, add another part bleach.

  • Place a fan in the garage once the mold is completely gone. Put a dehumidifier in the garage to prevent future mold growth.

Tips & Warnings

  • Do not use detergents that contain ammonia. Ammonia mixed with bleach creates noxious, poisonous gas.
