Abstract

The instant invention is directed to a corrosion inhibiting admixture comprising: (A) 10 to 90%, by weight, of a water-soluble orthophosphate compound, and (B) 10-90%, by weight, of a polyether.
The instant invention is also directed to the use of the admixture in inhibiting corrosion of steel.
