• Trombone Care Instrument Instructions

Trombone care and maintenance

To assemble your trombone, attach the slide section to the bell and hand-tighten the threaded collar. Then insert the mouthpiece into the receiver until it stops. If this is difficult do not twist or tap it into place. The mouthpiece should be removed each time you play by gently pulling it straight out. If it becomes stuck do not try to force or twist it off or use tools of any kind. The brass used in your instrument is very soft and excessive force can cause the instrument to bend and break. Your local music store and many music teachers have a special tool to safely remove a stuck mouthpiece.

When not using your instrument, keep it in its case to help protect it and prevent possible damage. Never store lesson books or music in the case because the pressure on the tubing can cause damage. Be sure the mouthpiece and other accessories are put away properly so they don't jar loose and cause damage.

The trombone will dent easily. Even a small dent in the main slide will hamper the slide action and make it difficult to play. Misusing the slide or leaning on the slide when it is resting on the floor will cause it to bend or dent. Always remember to lock your slide when you are not using it.

While playing, the inside of your trombone collects moisture from warm air blown into it. This moisture must be removed during and after each use by opening the water key into a suitable container. Remove oils and perspiration that can damage the finish by gently wiping the outside of your instrument with a lint free polishing cloth.

The mouthpiece should be cleaned weekly using warm (not hot!) soapy water and the mouth piece brush to remove deposits and keep your instrument sanitary.

Every month or so, your instrument should be disassembled and cleaned to remove the dirt and deposits that can collect inside. Instructions for giving your trombone a bath are located below. Regular cleaning not only helps keep your instrument sanitary but also ensures your slides are working their best.

Even with regular cleaning, plan to have your instrument serviced on a yearly basis by a qualified repair technician. Early summer is a great time to do this. Annual maintenance will keep your instrument in optimal playing condition for years to come.

To give your trombone a bath:


1.  Take the trombone completely apart.
2.  In a large sink or bathtub, soak all the parts in warm (not hot), mild soapy water.  Don't leave the trombone in the water too long or the lacquer finish can peel off.
3.  Run a cleaning snake brush through all the tubes.
4.  Rinse all the parts in clean lukewarm water and dry with lint-free towel.
5.  Put the trombone back together.
6.  Grease the tuning slide using tuning slide grease, wipe off excess.
7.  Apply a few drops of slide oil to the slide and lock the slide lock.
