OK I've done this on mouthpieces in the past but not on trumpets. Basically I have a few questions.
1) I was told to put in a tablespoon of bi-carb soda and two table-spoons for salt for a reasonably large tub for trumpets. This seems like a lot... is it too much?
2) What procedure should I follow when doing it? Do I need to take the trumpet apart? When I dry it and let it drain, how and for how long?
Basically I need an overview of what to do
