I've got a number of old estates with silver repair bands. How do you all protect the briar when your bands need to be polished? Medical tape, as a buffer, leaves a gummy residue and I'm leery of removing the bands so I can restore the luster.
Blue tape for heavy duty stuff, if its just tarnished some I.e. a little black..I've got a jewelry polishing cloth that doesn't need any solutions and doesn't harm the wood

Useful though the tape method might be, I could not stick tape on my pipe. I too have a pipe with a band that needs to be shined and I will end up using jewelry polish.
I picked up a two pack of Cape Cod Cloth at the local hardware store after seeing it highly recommended on the internet. It works great on silver bands. It's currently on sale on Amazon for $4.29. There's also a tin with 12 cloths for $13.86 on Amazon, but two should last a long time. I wipe it dry with a soft cloth after using it.
