Abstract
The present invention is directed to the chemical removal of adherent nickel deposits on plating racks and the like employing a composition which contains therein nitric acid and sources of chloride, copper and tellurium or selenium ions and to a process for stripping such unwanted deposits from electroplating apparatus without noticeable damage to the base metal and at speeds not normally obtainable with prior art compositions and methods.
