My 4 month old lever harp has a couple wire bass strings that are discoloring. They were shiny silver, but now one string is nearly all copper-colored, and the bottom 4-5″ of another string is getting spots of copper on it too. I don’t think it’s rust. But could it be? Or is it common for wire strings to tarnish? What do I do about it? I don’t think the tone is compromised, but it doesn’t look as pretty.
Is there any way to fix these strings? And what can I do to prevent this in the future?
