Taking Care of Your Instrument  Taking care of your instrument is very important.  There are ten steps to cleaning your instrument.
1. Fill up a bathtub with almost warm water to the height of the trombone.
2. Add a small bit of dishwashing detergent.
3. Take the trombone apart, including the slides.
4. Put the trombone in the water and leave it there for about ten minutes.
5. Run cleaning utensil, with a bit of Kleenex, through the tubing and mouthpiece.
6. Rinse all of the dishwashing detergent out of tubing.
7. Dry the entire trombone.
8. Place some slide oil on slide and tuning side grease on the tuning slide.
9. Oil the F-attachment if it applies to it.
10. Put the trombone back together.
Do NOT use extremely hot water when cleaning your instrument.  It will take off the plating of your trombone and ruin it.
How much you clean your instrument depends on how much you play it.  If you play all the time you need to clean your instrument every two weeks.  If you only play it every once in a while, wash it every month.
