If the silver plating seems to be scratched, I have had good luck with the products that are used to silver plate circuit boards. I don't recall the product name that I used, but it was/is available from Digikey and such. I merely used fine steel wool to polish the plunger and then used the silverplating kit to re-plate it.
Here is one product I ran across in a google search: http://www.cool-amp.com/cool-amp.html WARNING: The silverplating plating is NOT very thick. It won't take much to scratch it back off, but if you lube the finger stock with a conductive lube it will last longer. I have used no-ox in the past, but Cool-amps's "Conducto-Lube" might be a better choice. I have had no experience with it.
