~Slide/Cork Grease
~Brass Soap

Maintaining valves
>Remove valve caps at one time
>Wipe away any old oil at one time
>Add bearing oil on top of the surface where you can see the spindle turning in its collar
>Replace valve caps also not to cross the very fine thread.
>Light finger tightening is all needed. (do not over tighten the cap!!)
>For the bottom bearing a drop of bearing oil is added to a small gap between the fixed collar and the rotating part of the valve.
> Turn the horn on its back and move the levers for a few seconds until the oil is well into the bearing.
>Check that the oiling under the valve caps does not check that the marks incised at 90 degrees line up when the valves turn.
>If the marks do not line up it will mean that the corks or rubber stops underneath have worn and that the valves will not be opening properly.

For slide...
>Remove slide from the instrument
>Wipe of any old grease from the slide using a tissue (add oil)
>Take a little grease on the end of your finger and gently wipe around the middle of the slide
>Do this every couple of weeks
>Ensure no grease is build up at the end of the slides.
>Gently pull the slides out from the instrument.

Cleaning Inside & outside horn
>Use a long wire brush and insert it into the tuning slide of the horn
>Gently push the long wire brush into the tuning slide until it comes out of the mouthpiece end ( from larger to smaller diameter)
>Then gently pull from the mouth-pipe end until the whole wire has come through the pipe (repeatedly)
>Use a polish (lacquer/silver to clean)
>Make sure hands are wash cleanly from sweat
>Polish only ONCE a month. Do not polish too many times
