Abstract
This invention relates to a method of inhibiting the corrosion of flux-treated metal surfaces. The method comprises the step of contacting the flux-treated metal surface with a formulation comprising a corrosion inhibitor composition comprising one or more mono-carboxylic acids, or salts or isomers thereof, and an effective amount of a corrosion inhibiting surface active agent such as a water soluble alkali or alkaline earth metal nitrate salt. This method has been demonstrated to be a surprisingly effective means to inhibit corrosion of flux-treated metal surfaces found in the cooling systems of internal combustion engines.
