    I noticed the marks where the metal was gone, which occurred within the last few days, and asked a specialist about it who diagnosed it as red rot. I don't have contact with him at the moment...what do I do about it...just a normal bath? get a shop to chemically clean it? how much time do i have until it starts spreading, since there's only a handful of small marks at the moment? Will it trash my horn no matter what I do? I really can't afford another...

    Keep the horn clean and swab the affected part with a swab and then coat the inside of the slide with valve oil every time you oil your valves.

    Depending on how old you are,
    the horn will probably outlive you.
    So no too big worries on the latter;-)

    Also: where exactly on the trumpet have you spotted red rot?
    Leadpipe, main tuning slide?

    Take a deep breath, exhale, and relax. It's a very slow, sloth-like process that won't destroy your horn quickly. I would add to Brekelefuw's advice to check and lube your tuning slide more often. Depending on the products you use, valve oil can /will break down the slide grease to where it will move with gravity! Dings to bell and slide can happen!

    often, the 'red rot' is still superficial, and easily remedied
    take a blitz cloth to it and keep it protected with MAAS polish and protector, this will stop the 'rot' on the outside.
    if it is from within and through the professional help

    As a last resort, you could always have it patched or have the part replaced. You shouldn't
    have to replace the entire horn.

    Red rot takes a LONG time to create a pinhole. When a few do go all the way through (if you still own the horn by then), a good tech can fill them with a touch of solder and polish it smooth. I was just discussing this with Bill Deiss at Southeastern the other day, and he told me that when viewed under a microscope, the brass in the area where the zinc has leached out has a mesh, or spider-web look to it. When done correctly, the solder will flow into those voids and bond with the brass, creating a very good, hardly noticeable fix, even on a non-plated brass instrument.
