A composition and method of inhibiting white rust on galvanized steel in water system. The composition preferably comprises two parts, a first part comprising oleylamine and optionally comprising 2-diethylaminoethanol and cyclohexylamine, and a second part comprising phosphonobutane tricarboxylic acid, tolytrizole, and a polymer, and optionally comprising a tracer or sodium hydroxide. A preferred composition comprises two commercially available products, Cetamine V217 S and Chem-Aqua 31155. A preferred method of inhibiting white rust comprises adding the two parts of the composition or two commerically available products to the water in a water system to be treated in an amount sufficient to provide a concentration of the first part of around 200-500 ppm and of the second part of around 50-150 ppm. |
