Hey, here's a testimonial to the power of Tubenet:
I've got a nasty old Couesnon tuba and the third valve was just driving me nuts.  Sticky, plus it felt gritty.  So I did a search on the BB using "sticky valves" as the keywords.  Suggestions I found included:  buff the valves, use blue juice, clean the gunk out of your horn.  So I did "all of the above."  Lots of green gunk flushed out of the leadpipe.  Plus I used a stiff tootbrush to clean out the keyways.  The valves aren't "like new," but they are so much better than before that I can stand to play the horn again.  Thanks.
