From their website:
"For mildew you will want to try our fungus-removal formula. We copped it from the U.S. Government Department of Forestry. It consists of a third of a cup of powdered laundry detergent, 1 quart of liquid chlorine bleach. Any brands will do. You will also need 3 quarts of warm water. Add the bleach to the water and then the detergent and mix thoroughly. Although this concoction is mild, you should use rubber gloves and eye protection. Spray the formula onto the affected surface, and when the black mildew turns white, it's dead. Rinse the area with fresh water and towel dry. Although the formula can be used on painted surfaces, it is a good idea to test an obscure area first.
Commercial mildew cleaners contain two active ingredients: sodium hypochlorite and sodium carbonate. The former is bleach, the latter is the primary active ingredient in most laundry detergents. Our formula costs about one-fifth the price of store-bought mildew cleaners and works just as well."
From me, proportions for a smaller batch:
3/4 C. bleach
1 Tablespoon detergent
2 1/4 C. water
