As a trumpet player... I might be able to help you..

I've removed laquer on a horn before... strong polishes will work with time. Laquer remover will probably work. A strong polish that is good at removing finishes and laquer is "car polishing compound." It comes in a green and white labeled container, usually. It is cylindrical in shape.

I suggest going to the store and reading the labels.. If you want to rub it away with polish, pick the one that says "Do not use on gold plating, for it will remove the plating." If you are going to use laquer remover, brush it on the jewelry, and cover it completely with plastic rap over night. This will trap in the fumes and cause the plating to lift from the surface quicker. You could fill an empty jar with the chemical and place the item within over night aswell.

Don't be suprised if you need to use scrubby pads to completely remove all the plating. They come in different grades of corseness. A fine grade will scratch less. If it comes to that, you'll want car polishing compound to polish out the scratches.

Boiling it several times in a pot of water might work too. It depends on the quality of the plating.


Then again, most the above processes are probably bad on the pewter. I've only stripped brass.
