Black mold found in your shower should be tended to quickly. Left to spread and grow, black mold can affect your health. Black mold spores grow quickly in warm, dark, moist locations such as shower stalls. By tackling black mold in your shower quickly you prevent it from spreading to your bathroom walls, floor and other areas of the bathroom. While there are commercial products available to remove black mold, you can get rid of it using supplies from home. After the mold is gone, keep a close watch to ensure black mold doesn't return to your shower.
Rinse black mold areas in the shower with plain water.
Pour 1/2 cup of disinfectant into a 1 gallon bucket then fill the bucket the rest of the way with hot water. Stir the mixture with your hands.
Scrub the black mold areas of your shower with a scrub brush dipped in the disinfectant solution. Change the disinfectant solution when it gets dirty and continue to scrub until the black mold spores are removed.
Fill your 1 gallon bucket two-thirds of the way with warm water, then add 1 pint of hydrogen peroxide. Soak a clean cloth in the solution then wipe down the tile and surrounding walls in your shower area. Any black mold spores that are invisible to the eye will be killed by the peroxide solution.
Wipe down your shower area with a dry cloth to remove all moisture. Turn on a ventilating fan or open a window to aid in the removal of moisture.
