    I obtained this wonderful piece of American craftsmanship(1953). The third valve sticks regularly. It is oiled everyday it is used. The valve has some reddish discoloration. How can this be fixed?

    Also got a Getzen Eterna Severinsen model 1973. The valves are the best I have ever used.

    Soak it in 50% CLR and water for 3 hours, LIGHTLY SOS it, rinse well. If this does not work it is the valve tube. Off to the tech you go....

    Keep in mind that the problem may be some gunk collected in the valve casing. Make sure you have a really good quality valve brush and clean the casing with the CLR as well. Then scrub it out well with soapy water, then with a rag with some rubbing alcohol on it. Hold the trumpet up and look through the casing toward a light and see if the inside of the casing reflects light like a very smooth, shiny surface should. If it is dull, repeat the above steps until it is shiny.

    As a last resort, buy some gun oil from a sporting goods store - the kind that has teflon in it. Liberally spray the pistons and the insides of the casings and let them sit, unassembled for several hours. Then wipe both the pistons and casings with a soft cloth and reassemble. Try playing briefly before adding oil to see if there is any binding between the valve and the casing.

    Something else that you might have around the house which is very good for cleaning the valve itself is lacquer thinner. Considering the apparent wear and corrosion of the plating, though, the advice of A.N.A. Mendez and ComeBackKid is the way to go on the first round. Need to remove/smooth out that corrosion first with as little good material removal as possible. Expect to work through several rounds of playing and thorough cleaning before that valve settles back in. Lacquer thinner can be helpful during those subsequent cleanings.

    You have probably already done so, but I would also make sure that the long curving lead pipe, tuning slide, etc. on that cornet are well cleaned. More room there to stack up corrosion and gunk than on a trumpet, and it all enters the valve body at that 3rd valve.
