Callet Trumpets       

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. 

Amado Water Keys ~

Amado water keys create less turbulence in the airstream, 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 also works well and it's the best solvent for loosening a sticky Amado key. 

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. Weekly cleaning will keep deposits to a minimum. 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.
