Great idea! I have a sax bag that feels like it's made out of antitarnish material that I was going to use. But if it doesn't work, I'll try this out!
Well it seems to be doing well on the bell of my cavalier alto! I polished it with wrights silver polish last year, and then put on some of this wax.I don’t recall seeing suggestions of Ren Wax over silver plate - bare brass, yes. I like Hagerty Silversmith Polish.
