This is an unashamed advertisement- no I don't work for them, but I'm extremely impressed with all of the alisyn products, the most among which is the valve cleaner. It's on amazon, and I highly recommend it to any player who cleans their own horn. You spray it on, let it sit for a bit, and simply wipe it off. It gets rid of all of the mineral buildup from your spit that doesn't come off with normal cleaning. Not only does it extend the life of your valves, but it also keeps them quick and easy to play on. That is all.
