French Horn Care & Maintenance
Assembly
Keep the mouthpiece shank clean and check regularly to see that it is perfectly round. Insert the mouthpiece into the mouthpipe and turn it slightly. Do not "pop" it in with palm of your hand, as this may make the mouthpiece impossible to remove by hand after playing. Should this occur, DO NOT ATTEMPT TO REMOVE THE MOUTHPIECE WITH A TOOL. It must be removed with a special mouthpiece puller.

Regular Lubricating and Cleaning
Remove each valve slide (while depressing valve) and squeeze a few drops of oil down each of the slide tubes so that it will reach the valve. Rotate the valve to distribute oil. Every couple of weeks a couple drops of oil should be placed on the bearing shaft (moving part in middle of valve under the valve caps) Check all slides regularly to see that they move freely. Lubricate when necessary with a commercial slide lubricant after first removing all grease and dirt from slides. When removing valve slides, always depress the valve and hold it down while removing its valve slide. Put a thin coat of lubricant on each slide tube and insert tubes one at a time, rotating them to distribute lubricant evenly. Then assemble slide in its correct position. Always remove as much moisture as possible from the inside of the instrument after playing. Wipe the body of the instrument with a soft cloth to remove fingerprints.

Periodic Maintenance
Regular maintenance of the French Horn will go a long way toward avoiding unnecessary repair bills.
RECOMMENDED ACCESSORY ITEMS: Mouthpiece brush, flexible cleaning coil, cleaning rod, slide grease, rotary valve oil, polishing cloth (lacquer finishes only.)

ONCE A WEEK (or as needed): Wash the mouthpiece in warm soapy water and clean with the mouthpiece brush. Flush the mouthpipe tubing with clear LUKEWARM water using the cleaning rod and cloth to remove all particles and residue.

EVERY TWO MONTHS: Remove all slides and valve caps from the instrument. Place all parts in the bathtub or a large basin of LUKEWARM water and a mild detergent. After the instrument has soaked for a while, run the flexible brush though all body tubing and slides. Rinse thoroughly with a solution of baking soda and water followed by a final rinse with clear water and allow to dry. Reassemble the instrument, oiling the valves and lubricating all slides. This procedure will help to prevent corrosion from condensation and saliva inside the instrument. Finally, polish the body with a treated polishing cloth--be sure to use the appropriate type for your instrument (gold lacquer or silver plate). French Horn valves should be removed about twice a year for thorough cleaning. Have your teacher or an instrument repairman show you how to disassemble and clean the valves.
NEVER:
* Use hot water to clean the instrument, as this can cause serious damage to the finish.
* Store music books, folders, etc. in the case, as this may cause damage to the instrument.
