The first step when cleaning the trumpet is to disassemble and remove the different parts of the trumpet. Set the mouthpiece to one side on the towel you've laid out flat. Unscrew the top valves caps one at a time. Take the valves out and place them in order 1-2-3 on the towel. Then unscrew the bottom valve caps and place them in order underneath the valves. Finally, remove the first, second, third and tuning slides but lightly pulling on them until they are all of the way off the horn. Place them in order to the side of the valves. Next, take a sheet of paper towel and carefully wipe any oil off the valves. Pick up each slide and wipe any slide grease off the tubes. If the body of the trumpet has any inner slide tubes wipe any grease of these also. Now take a corner of the cotton towel and feed it through the eye of the valve
