Does Bleach Kill MoldBleach – does bleach kill mold?

Mold is a generic term for fungus. There are hundreds of fungus species, and yes, bleach can kill virtually every species you find indoors along with its spores.

Instructions: Mix one cup of bleach per gallon of water. You can use a sponge or spray bottle to apply the bleach. Letting the solution dry, without rinsing, will allow it to inhibit future mold growth. If the affected area is accessible to children or pets, then you may want to use a milder alternative or rinse the affected area. Bleach will also release harsh fumes, so make sure your work area has the proper ventilation before applying the solution and wear the appropriate safety equipment including respirator mask.
