Wipe surface of the countertop completely clean and inspect for defects and scratches.
process is essentially the reverse of electroplating. In a plating system, metal ions are deposited from the solution onto the workpiece. In an electropolishing system, the workpiece itself is eroded, adding metal ions to the solution. A typical electropolishing installation is similar in appearance to an electroplating line.
Polishing removes the artifacts of grinding but very little stock. Grinding uses ﬁxed abrasives—the abrasive particles are bonded to the paper or platen—for fast stock removal. Polishing uses free abrasives on a cloth that is, the abrasive particles are suspended in a lubricant and can
