An apparatus and method in which a coating is wetted with a solvent to initiate dissolution of soluble coating portions and the hydraulic pressure of the solvent at the surface of the coating is repeatedly increased and decreased to assist in the dissolution of the soluble coating portions. A brush with an array of bristles reciprocating in a path perpendicular to the coating may be utilized to produce the increasing and decreasing hydraulic pressure. Also, the coating may be immersed in the solvent to wet it and to initiate dissolution of the soluble coating portions. |
