Abstract
There is disclosed a cleaning and passivating treatment solution for ferrous metal surface comprising an essentially amine; alkanol amine and phosphate free aqueous solution of (a) from about 0.05 to 5.0% by weight of a caprylic acid derivative of imidazoline amphoteric surfactant, (b) a borate ion and (c) a molybdate ion wherein the ratio of imidazoline amphoteric surfactant to borate ion is from about 1:0.4 to 1:5 and the ratio of sodium molybdate to imidazoline amphoteric surfactant and borate ion is more than about 1:4. There is also disclosed a method of cleaning and passivating a ferrous metal surface.
