I'm sorry if this isn't the right group for me to ask this question but it looked like it, so I hope no one minds!
I bought some chess pieces in Greece many years ago and they seem to be made of brass though they could be made of an alloy, I suppose. They are reasonably heavy.
Anyway, at the time I bought them, they were coated to prevent dis-colouration but, over the years they have slowly discoloured. I can clean them with various, off-the-shelf cleaners but can anyone suggest the best way to re-coat them after cleaning.
I said "brass" but the pieces were of two different colours, originally, (as they should be) and I have no real idea what the materials are.
Regards,
John
