Fill a bath tub with warm water. Take out all the valves and the tuning slides on the instrument. Place the tuning slides gently into the water. Take the valves apart by unscrew and remove the pistons, unscrewing the key caps from the pistons and remove the felts (set these aside so they don't get wet) and place all parts, including the horn in the tub. Clean the horn and the tuning slides with a wire snake. Remove the horn from the bath and dry it with a towel. Reassemble the horn while greasing the slides and oiling the valves. You can use polish on the horn after the horn is dry to make it shine.
