With all the discussion of the care of trumpets, and since many on this site are obviously collectors (or obsessive/compulsive or manic), I think some recommendations for the care and storage of trumpets is in order. How can I ensure a horn will be in good shape if I only take it from its case once or twice a year? What will prevent red rot? What will KEEP the valves free, etc.....? (How do I pare down my collection?) - Not!
