I have decided to send my horn into the city to get cleaned by a professional and was curious to what I should do in the mean time seeing I wont get it back for over a week (long, I know...school instrument rush). Should I do mouthpiece buzzing....any suggestions? Or should I just give it a break.

O yeah and a question about the horn : the corks on the top of my pistons seem to be glued on. A couple of them have came loose. What should I do?.......what if I need to take all the corks/felts off for cleaning?

Thanks

Kevin
