Abstract

A method for inhibiting corrosion of a metal member of a cooling water system, which comprises: a step (1) wherein one or more compounds (A) selected from among tartaric acid and tartaric acid salts are added into the cooling water system, thereby being brought into contact with the metal member; and a step (2) wherein one or more compounds (B) selected from among zinc and zinc salts are added into the cooling water system after the step (1), thereby being brought into contact with the metal member.
