To keep your horn in superb condition, please follow this advice: Lubrication is required for the bearing at the linkage end (not under the valve cap) with a thin spindle oil on the end of a small screwdriver, using a thicker oil or grease for the lever linkages. This should be done once a month.
Finke valve-rotors usually work with no more than water lubricant – to prevent build-ups in the casing the rotors are installed with a drop of thin oil on the surface. If it becomes nevertheless necessary to oil the inside of the valves we recommend the products T2 from „La Trompa“ and „Blue Juice“. They can be applicated through the slides.
Should the instrument not be used for a long time it should be rinsed through with distilled water before use. If a cleaning-brush has been used in this process, always rinse afterwards with plenty of water.
We recommend to clean lacquered Instruments with soft cloth, regular. To remove water drops (on the bell flair, etc), use lacquer-polish. These are available at your dealer. Special cleaning-sets are recommended to clean the inside-tubes.
