I have no idea ! Who knows, please? Is it taking metal out of my horn? It comes out dark brown after sitting overnight from both standard spit valves and Amado keys.

marsuleu

maybe you should clean your horn before applying oil . I don't think that an oil could destroy your horn inside ...
how come the oil comes out ?!? this is weird ... where and how much did you applied ?

Thanks, Marsuleu,
The color also shows in the bottom caps some, and when I drain the spit valves. This is main and third slide valves, whether on the YTR6320S with the black rubber spit valve cork, or the Bach MtVernon with the Amado keys which I soldered on. I could send some of the liquid to Alisyn I suppose. Both horns are very clean. I first noticed it on the Bach and wondered about the springs in the Amado keys being not stainless and somehow the valve-slide-key oil encourages oxidation, but the Yamaha once I started using the oil there did the same thing. The color is toward the red spectrum, but brass includes copper so maybe it is not the iron. But copper oxide is green, so it would have to be unoxidized brass. I use as much of this oil as one would a standard oil, not the few drops recommended. I bought a quart. It happened also when I was buying small bottles. The Bach has worn valves and needs it to not stick, the Yamaha needs oiling every time I put it away or it will be slightly stuck next day. Maybe it is just unavoidable brass oxide being flushed out.

change the oil ! use something synthetic ( Yamaha, UltraPure ) and see the results.

You have more than one kind of oil in your horn, and the Alisyn is reacting with it. Clean your trumpet very well, and then the Alisyn will work perfectly. Everyone eventually learns to NEVER mix oils, and never borrow different oil from someone on a gig. It doesn't happen every time with every oil, but that's what is happening.

Remember, one brand of oil at a time. Switch brands? Clean the horn first.

Thanks, Grizzle. Yours seems the best answer. I will try it. As to changing away from Alisyn (which is synthetic), it would need to be to something thick like the Alisyn to work on the Bach. If that is needed, any suggestions for a slightly thicker oil? Now I suppose I will get a whole bunch of favorites ... or not.

Grizzle

I'm not too into oils, but I use Alisyn and dig it. But oils combine with the pH of your breath, the metal, and the oil and combine differently for different people. There are other people who can answer your question better than I.

I have used Alisyn oil for years and I like it a lot. It has never turned dark on me, even if I have used it on horns that had been lubricated with something else. So, it must have something to do with your personal chemistry. If you bought a quart, I would suggest giving a sample to a few friends to try and see if it happens on anyone else's horn. Also, I suspect there is something else going on as I have never seen oil come out of a spit valve. That is really weird. Yes, take the previous suggestions and give your trumpets a thorough bath and use the snake to insure that all possible foreign material is removed then try the oil again. You really need to figure out what is causing it.

As with all problems, change only one variable at a time ....... but still, if a solution results, the complex chain of effects mechanism of the removed variable is still unknown. Go back and change a different variable. No one has said anything about rust of the Amado spring. I took the Amado off a cheap pocket trumpet, maybe it is not rust-free. I am not whining, I appreciate all your attention. But my eye says the color is iron. Does any oil advertise as an anti-oxidant? I forgot to say that sometimes I put a whole bunch of Alisyn in the receiver and blow it through. This is unusual as if you don't have a quart (most people) you wouldn't want to "waste" that much. But, it also occurs just with normal at-the-valves oiling. The valves are definitely sloppy, maybe they are to the point that any oil would flush away metal that is being ground up. Also, I have little sticks of foam plastic inside my valve springs to stop them being little reverb units (a definite sound change but very subtle). I will see whether Alisyn is dissolving them.
