The apparatus, system and method utilize sequential sprays of wet, low-temperature steam, and dry, high-temperature steam to clean the exterior of laminated objects as well as to effect volatilization of liquid contaminates trapped between lamina thereof. Water is injected into the conduit through which the low-temperature steam is delivered, so as to produce a desirable concentration of droplets therein. A conveyor moves the laminated objects along a horizontal path through zones in which they are sprayed by the low temperature and high temperature steam, and then through a zone in which they are electrostatically coated with powder.

A method for cleaning and coating a workpiece contaminated with a volatilizable liquid, comprising the steps: a. transporting a workpiece contaminated with a volatilizable liquid along a travel path, and carrying out the following steps during said transporting; b. discharging wet steam upon said workpiece so as to substantially remove said liquid therefrom and elevate the temperature of said workpiece; c. discharging dry steam, having a temperature higher than said wet steam, upon said workpiece so as to further elevate the temperature thereof; d. exposing said workpiece to a cloud of electrostatically charged particles with said workpiece at an electrical potential effective to attract particles of said cloud thereto, to form a coating thereupon; e. cooling said workpiece between said steps c. and d., as necessary to prevent fusion of said particles of said coating during said step d; and f. effecting fusion of said particles of said coating on said workpiece subsequent to said step d.
