Thanks for all the replies. Rowuk – as to your question above, no, I’ve never had a problem like this before. I’m usually on the horn six or seven days a week, so I try to clean it out at regular intervals. I think I’ve averaged every three weeks since I’ve owned the horn. I’m also fairly religious about brushing/flossing before I play. The only exception to the rule is beer during the summer, but all my horns understand that beer is going to be a condition of their existence in my hands :)

I’ll try plugging the pipe and pouring some vinegar in and see if that works. It’ll be a great cold-weekend project, at least for a half hour or so.

Later,
