ELECTROCLEANING PROCESS Abstract of the Disclosure A process for electrocleaning articles comprised of a substrate having a copper coating thereover to remove adherent and embedded contaminating carbon particles from the coating, rendering the article in suitable condition for further electroplating operations. The electrocleaning treatment in- cludes immersing the article in an aqueous alkaline solution containing a controlled effective amount of an inorganic com- plexing agent possessed of copper solubilizing properties and effective to retain the solubilized copper in solution in the form of a complex. The article is cathodically electrified continuously or on an intermittent basis for at least a portion of the period while immersed in the aqueous alkaline solution to accelerate the solubilization of the copper and the dis- lodgment and removal of the contaminating carbon particles, whereafter the electrocleaned article is rinsed.
