I use Al Cass valve oil and do not apply pressure on the 2nd valve elbow.
I just bought a Xeno C horn and cannot afford a new Bb.

Wynton,
I've heard this story before and its one of the reasons I don't do chemical cleaning - it can leave residue in places where it shouldn't be. The process I use is low-pressure steam cleaning (LPSC).
The advantages of LPSC include:
1) Your horn doesn't get abused by harsh chemicals
2) Your horn is not submerged so dirt and grime from one part of the horn doesn't float into another part of the horn
3) Its quick - only takes about 30 minutes total
4) It sanitizes
5) Also, it removes minerals left behind by chemical cleaning
(I have pics if anyone doubts me)
If you are interested in LPSC then send me a PM.
I also would avoid AL Cass and go with Zaja, Pro Oil, Blue Juice or Clark's Viper oil. Also, I would never try to clean the horn or valves while they are in the hron.
Good luck,
Greg
