Ron, If your flatware is plated I suspect there is not much you can do to remove the pitting without removing the plating. If Sterling your flatware will do well to be rubbed with something a bit more agressive than rouge. I might suggest Semichrome polish on a rag. Do not use a buffer. The chances of damage are much greater if you use a buffer. When the pits are clean use the a commercial silver polish and wipe clean with soft cloth.
