Abstract
An improved composition for selectively stripping gold from a metal substrate, especially copper metal, wherein the gold deposit is rapidly and effectively stripped without an attendant attack on the metal substrate. A minor amount of an organo mercapto compound, e.g. mercaptobenzothiazole, is added to the stripping composition to inhibit attack on the metal substrate.
