Care and Maintenance of a Horn
Weekly care and maintenance

1. Press the lever to release pressure so that removing the slides does not cause a popping sound.
2. Wrap a polishing gauze around the cleaning rod so that the metal is not exposed, and insert it into the slide to remove dirt from inside.
3. Wipe the outside of the slide to remove any dirt and then apply a small amount of slide grease. Move the slide back and forth to make sure that grease reaches all parts of the tube.

1. Remove the rotary valve cap, and apply a small amount of rotor spindle oil to the center of the rotor and the place that supports the spindle.
2. Apply a small amount of rotor spindle oil to the rotor spindle and the rotor bearing. After applying the oil, replace the cap, and move the levers to work the oil into the rotor.
3. Apply a small amount of lever oil to the bearing in the lever base.

Make up a solution of brass soap, consisting of 10-15 parts warm water (30°C-40°C) to one part brass soap. Put some brass soap solution on the mouthpiece brush and put it into the throat to wash, and then rinse with clean water.

Twist a piece of gauze into a thin strip and run it through the narrow parts to clean them.
