A treatment for controlling the deposition of scale imparting species on the structural surfaces of steam generating systems, wherein the aqueous medium is maintained at a pH which minimizes magnetite solubility, comprising the use of a combination of an organic amine and a nonionic polymer having the structure: <IMAGE> wherein R1 is H or lower (C1-C4) alkyl, R2 is (CH2-CH2-O)n, <IMAGE> or a mixture of both, n is an integer of from 1 to about 40, and R3 is H, lower (C1-C4) alkyl or an acetate.
