Abstract
Hydrogen peroxide rinse aid solutions of the present invention added to hydrochloric acid rinse baths for acid pickled stainless steel enables hydrochloric acid rinse baths to easily remove stainless steel oxides and smutt from the surfaces of acid pickled stainless steel to produce a bright and clean finish that is comparable to the finish produced by nitric/hydrofluoric acid rinse systems.
