Electroleaning is a cleaning process used in metal surface preparation, usually in preplate cycles. It is essentially characterized by the use of DC current and a specially formulated electrolyte. The work being processed may be used as anodes or cathodes, or both, depending on the application. Although electrocleaning is a different and distinct method of surface cleaning, it should be considered in the context of the complete surface preparation or preplate cycle. Such a general cycle might include: (1) soak clean, (2) rinse, (3) electroclean, (4) rinse, (5) acid activate, (6) rinse, (7) repeat steps 3 to 6 (optional), and (8) plate.
