    I second the Maas polish with a microfiber cloth. That stuff polishes any metal to a mirror finish. Amazing stuff. What kind of horn is it, anyway? Good luck!

    What kind of case does the horn have? Sometimes cheaper cases off-gas sulphur gas from the rubber/plastics, which causes silver to tarnish.

    Oh well my case doesn't have much rubber. Its more like a duffel bag strap on case. But it doesn't have much rubber inside it. Just the handle straps are rubber

    Pure silver oxidizes, as does any product with a higher content of silver. Silver in the presence of industrial air or carbon combustion seems to oxidize / tarnish more rapidly. Silver plated instruments never fared well in cigarette/cigar smoke laden venues.

    I did say that I had been told about silver by one source and I certainly don't only believe one source. I do try to find the most correct info I can and I welcome your input. I did think though after my earlier posting, what about coin silver? I just remember back in the day when they made coins out of real silver that they did not tarnish very fast and I thought they were fine silver. I have also done some research since and have found that the thing that tarnishes silver is contact with sulfur and that the resulting sulfur oxide (tarnish) is black not brown.

    I sure do not claim to be an expert and I am not a chemist but I think I will stand by my earlier post speculating that the instrument was plated with a product with less than a desirable amount of silver in it.

    Shame. I scanned some of the replies and it could very well be a poor quality instrument.
    In support of the humid climate theory, I live in Michigan. It is very humid here in the summer sometimes.
    A couple of weeks ago, my Bach Chicago C (which is also silver) developed some brown spots.
    I did polish the trumpet and they went away. But it was humid the next week and the spots returned.
    I too advise you give the cashier a piece of your mind.
