More often than not, the effectiveness of a cleaning process utilizing Alkaline Chemistry, is dependent upon the generation of energy in the form of heat, solution movement, or impingement at the part solution interface. Utilizing a controlled electric current (from a Direct Current power source--a Rectifier) has long been an established technique. The loss of "Triclor" as an in-process cleaning chemistry has renewed the value and the potential of this method of cleaning in industry. Voltage pressure can be applied over a wide spectrum of part configurations for both racking and bulk processing considerations. From thumb tacks or air rifle BeeBee shot to 48 inch reel-to-reel steel finishing, this cleaning tool is available. Today's technology allows us to employ self-regulating, precise voltage & amperage, in conjunction with alkaline chemistry to enhance the removal of soils. Direct cleaning (D.C.), Reverse cleaning (R.C.), Periodic Reverse cleaning (P.R.), Interrupted cleaning (I.R.), as used in conjunction with or independent of other alkaline cleaning methods will be explored. Process cycles, what happens at the metal/chemical interface, soils and their response to alkaline/electro processing will be offered as a guide to maximum utilization of the process.
