The following is a Jupiter Baritone sent into the shop because of valves not working.  According to the customer, the instrument had been cleaned the following summer and had not been played very often during the year.

Upon inspection it was determined this instrument really needed to be cleaned Ultrasonically.

residue accumulating inside tuning slide ...

outer slides were dirty as well

More expamples of dirty outer slides

These are the bottom valve caps, notice the build up (the black sections) of residue

More build up of residue around the edge

These are the valves of this 4 valve baritone after removing the valve guides.  Notice the residue build up around where the valve guides were located.

The instrument is checked for reachable dents and those dents are removed, then it is dissassembled and degreased in a tub.  Once we've cleaned out as much as we can with a brush, it's time for the instrument to be placed into the Ultrasonic tank.

Here is the baritone in the Ultrasonic tank.  Notice the water is clear and look at the left hand portion of the picutre and see the valve caps.  The black cloud rising from the caps is the build up of residue being removed by the ultrasonic sound waves.

Notice more residue being removed from the inside of the tuning slides

After the instrument is cleaned in the Ultrasonic tank, it is rinsed in a rinsing tub, and dried.  All parts are checked over to ensure all residue is removed.  Slides are treated with slide grease, valves are cleaned and oiled.

Here are pictures of the final result ...

Clean valve caps, notice they look almost like they did out of the factory

valves are clean

slides are very clean, free of residue that can cause the slides to stick and become frozen
