Well the thing is though with old horns, corrosion is often caused by neglect, not a lack of oil.
Oil will dry out over time, most will anyways. That leaves anything open for rust/corrosion. If you regularly oil your valves and clean them, absolutely no dirt will build up, even if your saliva is acidic. If you keep your slides greased, you'll have no corrosion or stuck slides there. The major problem with stuck slides is that even if they were greased they must have been neglected. After all, how many times are horns neglected for a few decades after they've been thorougly cleaned? In fact if you cleaned a horn completely before storing it somewhere you may not find many corroded parts - if you pulled the slides out first anyways, washed everything with soap and water, and put one last coat of quality oil before storage. Either way, just like with automobiles, a final coat of oil on the important parts will save it from corrosion if you were to store it for a while. However of course my point was that if you're going to clean your horn you might as well get all the oil out and start from scratch. I know that my valves will get sluggish if the bearing/valve oils ever mix, and if slide grease works its way into the valves it'll progressively get worse. Moisture in the valves aren't usually a problem but I still have to manually dry them out sometimes. It reminds me of how they store automobiles. There is a lengthy process before a car can be stored for many years so that there is no corrosion and damage to it from neglect, I think. Just like an automobile, if a horn is properly stored for a lengthy period of time after it is prepared for storage it should last a while. -William In a message dated 9/8/2004 6:52:15 PM Pacific Daylight Time, [EMAIL PROTECTED] writes: If you ever remove an old branch or tuning slide bow and cut it with a saw, you can see just how green and corroded the inside can get. A light film of oil will protect the inside of the tubing from being eaten away by acids.
