Care and Feeding ~

Valves ~

The valves on the SIMA are machined to extra tight tolerances in order to provide years of fine service. This added precision requires some break-in time. During the first few weeks of service, use a high quality valve oil of light consistency every day. Before applying the oil rinse the valves and casings in lukewarm water to insure that any residual metal shavings are flushed out. The valves will get smoother and faster with every use. And, the blow of the horn will open up in a matter of days. Allow apx 2 weeks of regular playing before the horn fully "blossoms". 

Deep cleaning - Hanging valves are most frequently caused by pushing the valve a bit from the side rather than straight up and down. This is why the 3rd valve much more frequently hangs than others. But just a little dirt or grime on a tightly machined valve can also cause a valve hang up. Even changing to a different valve oil can cause problems. But the fix is quite easy. Remove the offending valve plus its lower valve cap. Coat the valve with Ultra Brite toothpaste (or any other toothpaste that has a little grit in it). Then, insert the valve up through the bottom of the casing and spin it around for a minute or two until it feels smooth. Rinse valve and inside of casing very thoroughly with lukewarm water and mild dish washing soap. Re-oil and test. You may have to repeat the steps two or three times for a very stubborn valve. But don't worry, the toothpaste is very mild so you won't do any harm to the valve as long as you follow the above steps. In our experience, this simple procedure solves over 98% of valve problems on Callet trumpets that have not been otherwise damaged.


Amado Water Keys ~

Amado water keys create less turbulence in the air stream, but they require a little extra care. Weekly, put a few drops of valve oil in both ends plus the opening of the water keys while pushing the button in and out. A valve oil of heavy thickness is best. WD-40 works even better and is the best solvent, in our experience, for loosening a sticky Amado key. For Pollard water keys please click here: Pollard water keys


Finish ~

The finish of your SIMA trumpet is best cleaned with mild soap and water. For deeper cleaning on silver plate use a mild silver polish, but only do this occasionally as polish does remove some silver. On the gold lacquer finish, spray with Pledge furniture polish then wipe with a soft, clean cloth.


Inside ~

Each week, flush the inside of your trumpet with lukewarm water. Each month, add some mild dish washing liquid soap and rinse thoroughly. Use a trumpet or trombone cleaning brush, particularly in the leader pipe, to remove accumulated deposits. On reassembly, squirt a coating of valve oil down the leadpipe. Weekly cleaning will keep deposits to a minimum.  If you have highly acidic saliva, a daily pull-through of a leadpipe swap is also a good idea. And if you drink colas or coffee, always rinse your mouth thoroughly before playing. Cola, in particular, is highly corrosive. If you drink cola or coffee during a gig or practice session, be sure to rinse the horn well that same evening or by next morning. The life of your horn will be improved and so will your intonation!


Slides ~

Use a high quality slide grease to keep tuning slides in top condition. A valve oil of thicker conditionally works well to keep the 3rd slide fast and smooth. on this slide, some players prefer slide grease thinned with valve oil.


Felts and Corks ~

For typical use, replace felts and corks every two years. For heavy use replace every year. If your horn begins to feel stuffy then replace more often. Use felts and corks of the same thickness as the originals. These are readily available from quality horn technicians as well as directly from Kanstul.
