    I have a Getzen 700SP and the silver finish on the valve casings on the horn is corroding. Any help?

    That description does not quite make sense. The valves are not silver - most likely nickel. I assume that you are seeing some discoloration on the pistons that you call "corrosion." But, unless the trumpet was left sitting with the valves out in the weather for years, that is not corrosion. It is probably areas where the nickel plating is wearing thin and the underlying brass is showing. That wear results from not having proper lubrication. Just thoroughly clean the pistons and casings (wash the entire trumpet while you are at it - many posts here explain how), oil properly and they should last for a long time. The valve wear does not destroy the trumpet - yet!

    I meant to say the valve casing. My silver plate on my horn is coming off around the valve casings.

    Apart from having it professionally replated, there is nothing you can do. This is indicative of one of three things,
    i. acidic perspiration on you hands passing to the plating and breaking it down,
    ii. neglect of the mandatory wipe down when finished - every time you pick up the trumpet or,
    iii. a combination of both i and ii.

    I have sweaty hands and always put a valve hand guard on all of my hammers. It will protect from further dammage and cover up the wear already there. Some can be stylish, but I prefer understated black! Best wishes.

    You can use a valve guard, or get some clear nail polish and paint it on the corroded spots. That is what I do.

    You can touch up silver plating with a plug n' plate silver kit and/or Silversmith pure silver plate polish both available from Caswell.
