I just bought an old martin and after playing yesterday I still have a weird "brassy" aftertaste in my mouth and my throat's a little sore. It was chemically cleaned before I bought it, but there is a little crud still on the inside of the leadpipe. I'm not sure if it's just some leftover chemicals from the cleaning that I need to rinse out or something else.... should I be worried that my mouth still feels a little weird 24 hours after last playing the horn?

i'm concerned that it may be red rot in the lead pipe. luckily thats the only place there's anything like that on the horn. is that dangerous? I'm planing on getting the pipe replaced eventually-red rot or not, it's banged up a bit, but would that possibly be a health hazard i should take care of now?

What kind of Martin are we talking about?
I'd give the horn a bath in some hot, soapy water...don't use anything too abrasive, though. Run a snake through the whole horn, let it dry, and re-assemble.
Is the mouthpiece that you're playing old, too? Wash out that as well.
Good luck

It might be the tase of verdigris--some real nasty stuff:

Verdigris is the common name for the chemical Cu(CH 3 COO) 2 , or copper(II) acetate. It commonly occurs by the action of acetic acid when copper, brass or bronze is weathered and exposed to air or seawater over a period of time. Its name comes from the Middle English vertegrez, from the Old French verte grez, an alteration of vert-de-Grice — verd (green), de (of), and Grice (Greece)— "green of Greece".

The vivid green color of verdigris makes it a very common pigment. Until the 19th century, verdigris was the most vibrant green pigment available and frequently used in painting. Verdigris is lightfast in oil paint, as numerous examples of 15th century paintings show. However, its lightfastness and air resistance is very low in other media. Copper resinate, made from verdigris, is not lightfast, even in oil paint. In the presence of light and air, green copper resinate becomes stable brown copper oxide. This degradation is to blame for the brown or bronze color of grass or foliage in many old paintings, although not typically those of the "Flemish primitive" painters such as Jan van Eyck, who often used normal verdigris. In addition, verdigris is a fickle pigment requiring special preparation of paint, careful layered application and immediate sealing with varnish to avoid rapid discoloration (but not in the case of oil paint). Verdigris has the curious property in oil painting that it is initially bluish-green, but turns a rich foliage green over the course of about a month. This green is stable. Vergidris fell out of use by artists as more stable green pigments became available.

Verdigris is poisonous and has also been used in medicine and as a fungicide.

Copper(II) acetate is soluble in alcohol and water and slightly soluble in ether and glycerol. It melts at 115 °C and decomposes at 240 °C. It can be prepared by reacting copper(II) oxide, CuO, or copper(II) carbonate, CuCO 3 , with acetic acid, CH3COOH 2 . It is used industrially as a fungicide, a catalyst for organic reactions, and in dyeing (The Merck Index , Ninth Ed., 1976).

WOW! Vulgano that's awesome. You delve into the voodoo side of things more than you let on, don't you?

Yeah, if you we using the mouthpiece that came with it i'd be more worried about that. old mouthpieces tend to have a slighty interesting taste...
