If you have an issue with black mold in your house, you should get it taken care of as soon as possible. Black mold can be dangerous, and will spread if not removed. The most effective way to get rid of black mold is to hire a mold remediation specialist. However, this option can be very expensive. The most inexpensive option is to get rid of the mold yourself with household cleaning products.
Put on rubber gloves to protect your skin.
Add a gallon of water to a large bucket, and pour in 1 cup of bleach.
Dip a sponge into the bleach mixture, and use it to cover the area infected with black mold. It will take 15 minutes for the bleach solution to kill the mold. Add more solution if it dries before 15 minutes are up.
Scrub the area vigorously with a scrubbing pad.
Rinse the area with a clean sponge soaked in plain water. Dry the area with clean towels.
