How to Remove Mold & Mildew From Colorbond
- 1). Put on protective eyewear and gloves.
- 2). Test the area by placing a drop of undiluted bleach on the suspected fungus. Wait a few moments to see how the area dries. A clean, dry spot indicates the likelihood that the substance is indeed a fungus.
- 3). Dilute the bleach so that the hypochlorite content is only 2 percent of the new cleaning solution. As most household bleaches contain approximately 6 percent hypochlorite, mix one part bleach with two parts water.
- 4). Add a small amount of household detergent such as dish soap to the diluted bleach solution to improve wetting. This step is optional.
- 5). Apply the bleach solution by using a soft-bristle broom to scrub the solution onto the entire area affected by the fungus. Saturated the area well, and allow the solution to sit at least three to five minutes.
- 6). Rinse the entire area thoroughly with water.
