| What I discovered is that the corrosion that I observed on my goldplated mouthpiece rim is actually from the silver plate underneath the very thin gold plate.
I was advised to use Silvo (supposedly a finer grit abrasive than many other metal polishes) and stop as soon as I was satisfied that the corrosion was no longer noticeable.
Using 3M anti-corrosion strips when storing horns and mouthpieces has been a great help in preventing recurance. |
