Abstract

A process of cleaning very sparingly water soluble soaps off workpieces after cold forming them is made considerably more economical by using a cleaning solution that causes the removed soap anions to form a separate floating solid phase that can easily be skimmed from the surface of the cleaning solution. When such a separation is made, much longer intervals between replacement of the cleaning solution are possible while still obtaining satisfactory results. A preferred cleaning solution for such a process comprises hydroxides, neutral salts, polymeric quaternary ammonium cations, and a sequestering agent for the counterions of the soap anions to be cleaned.
