ABSTRACT OF THE DISCLOSURE Disclosed are compositions and a method for repairing a damaged electrostatographic photoreceptor comprised of a conductive substrate with a uniform layer of selenium or a selenium alloy on its surface. The instant compositions contain amorphous silica of three distinct particle sizes. Scratches in the selenium layer of a depth less than its total thickness are polished with the instant composition whereby the affected surface area is buffed to a smooth finish. After application of the polish composition, the electrostatic effects of the original scratch are eliminated and the repaired photoreceptor will provide copies in which printout in the repaired areas is of the same quality as in the non-damaged areas.
