How to Clean Up Mold With Bleach

  1. Prepare the area for cleaning. Because bleach is a very corrosive substance, it is very important to create a safe environment for cleaning. Activate any ventilators close by, and open windows to allow fresh air to pass through.

  2. Put on safety gear. Bleach should never come in contact with your bare skin or be inhaled, so make sure to put on rubber dishwashing gloves and a surgical mask to prevent contact with the skin or respiratory system.

  3. Create a bleach concentrate. For killing mold, an acceptable dilution is 8 oz. for every gallon of water used. Make sure to shake the mixture thoroughly to ensure an even mixture.
