That's what she did do, and the stuff comes back.

  It sounds like it is some stuff left over from the manufacturing process.  Your repair lady could probably just target the offending port and give it a mini-chem cleaning to fix the problem.

    Question here;
    Am getting a black buildup in one of the ports of my third valve. The stuff is really hard to get off. I had my repairwoman look at it and she got it off with a chem clean. 
    Now a week later, it's back. She said it may be some kind of reaction. 
    The horn is a brand new Yamaha Xeno RGSM. I snake the leadpipe and tuning slide daily and the horn is clean but this stuff still shows up. It's like dug into the metal of the valve port. 
    I use Holton oil if that info helps anyone.
    Any ideas on how to stop this or clean it??

    Thanks!!~
