Trumpeters, use these helpful hints to keep you blowing and not green growing in your horn.

description	procedure	frequency
Blowout	Before playing, forcefully blow air through your horn, without moving the valves, to clean case fuzz and other stuff out of your mouthpiece and bore. This stuff can get into your valves and cause them to hang.	before each use
Oiling	Keep your valves oiled. Oil not only reduces friction, but serves to reduce leakage. Use the heaviest oil you can that still provides good action. See Warnings	every two days
Wiping	With a soft, dry cloth, wipe the fingerprints off of your horn. Empty the condensation out of your horn via the water keys, blowing forcefully to blow as much out as possible.	after every use
Cleaning	Remove the slides and valves. Pour cool, soapy water into the tubes several times. Use a "snake" to scrub the bore and pour more soapy water through. Rinse with clear water and let dry. Swish the valves in a jar or glass of soapy water. Don't get the felts wet. Scrub the ports with the snake's brush end. Swish the valves in clean water to rinse and let drain. Assemble with fresh oil and grease. Check water key corks by pressurizing the slide and looking for leaks. Best time to do this is during the soapy water pour through (Makes bubbles if it leaks). (You have tasted soap before haven't you, potty mouth?) See Warnings	monthly or more frequently if you feel you need to

IF IN DOUBT, DON'T!
