Abstract:
1. A corrosion-inhibiting mildew remover kit consisting essentially of a premeasured amount of an alkali metal perborate stored in a container; a premeasured amount of a liquid blend consisting essentially of a surfactant and benzotriazole and/or tolyltriazole stored in a container; and a premeasured amount of an alkali metal silicate stored in a container; wherein at the time of use said premeasured amount of the perborate, said premeasured amount of the liquid blend, and said premeasured amount of the silicate are combined with a premeasured amount of water to form an aqueous solution consisting essentially of: (a) from about 0.1 to 3.0 percent by weight of at least one alkali metal perborate; (b) from about 0.05 to 5.0 percent by weight of at least one alkali metal silicate; (c) benzotriazole, tolyltriazole, or a mixture thereof; and (d) 0.1 to 5.0 percent by weight of at least one water soluble surfactant; wherein the composition has a pH ranging from 7.0 to 10, does not include a chlorine bleach, and the combined amount of ingredients (b) and (c) does not exceed about 5.0 weight percent of the composition.
