    TAF, it sounds like you need to break down and take it in to be looked at by a qualified professional instrument technician. Advice from a forum will not be able to repair what is going on with your instrument. The sooner you tend to it, the better, from the sound of things.

    red rot is an nasty customer i had to replace leadpipes on my Bb and C because of it and will need to again. 6 months after getting it it already started pitting and within a year shows up. it is nothing you do, i clean my horns out every month too. the acid in your salivia that causes it. next time i am going to get gold brass leadpipes have heard that they resist corrosion better then the plain brass (stock bach) leadpipes.

    but i second alex, get it to your nearest repair tech.

    Keeping the lead pipe, tuning crook and mouthpiece clean will do a lot towards keeping the rest of the horn clean. I do this and the exterior of the horn every day, then clean the entire instrument every month. Brass is made of copper and zinc. The acid in our systems leaches the zinc from the brass. This is red rot. On laquered instruments this shows up as small pink spots, usually on the lead pipe as this is where most of the gunk from your mouth accumulates. On silver horns the plating flakes off. It is sort of like cavaties in your teeth. Much of this depends on the acidity of the individual's system. Brass is tough stuff and resists corrosion. This is why it is used on boats. But it is no match for a person with an acidic system.

    A note on the red rot. Usually happens in the leadpipe first. Cause is you.

    Your spit has calcium in it and if left to build up in the horn it reacts with the brass displacing the zinc. When the zinc is gone you are left with copper - thus the "pink" or "red" color. The copper is now porous and allows air to escape and your tone to go to pot. Once you can see it on the outside of the horn you know the inside is shot. Then your option is to replace the leadpipe - if it has gone father down the horn, then replace the horn. This is a non-repairable item.

    The periodic chemical cleaning is the prevention. But I would do the soap and water trick right after getting it back, followed by a lot of valve oil down the leadpipe before putting it back into service. The chemical clean can leave some sensitive surfaces.

    The green stuff might be the copper corroding, or maybe some really old roast beef.

    It does have alot to do with enzymes in your saliva, but when it gets ot the outside it could have something to do with the oil in your hands. I have such oily hands that when we march I have to wear cotton gloves and I always have a valve guard on no matter the situation. My horn is already loosing finish on areas where my skin touches it and is unprotected. Most notably the bottom of the leadpipe between the 1st and 2nd valve. Also, the area connecting the 1st valve to the bell crook. Nasty stuff. Darn my oily hands! :x
