Surface Preparation of Metals Prior to Plating
care and control as we do with plating processes. The day of the single cleaner tank is gone forever. Contemporary cleaning systems must remove oil, grease, scale, rust and inert particles. In other words, they must degrease, saponify, emulsify, acid dip (pickle), neutralize, activate, etc. in order to obtain a "clean" part for plating.
