Care and Maintenance of a Trombone
What do I need to do daily?
Prior to playing
Preparing the slide
3. Insert the inner slide into the outer slide, then slide the two sections back and forth several times to spread the cream evenly.
If the slide becomes sluggish while playing, moisten the slide with the water spray bottle. A small water spray bottle in your pocket could come in very handy when performing!
Oiling the rotary valve (tenorbass trombones and bass trombones)
On tenorbass trombones and bass trombones, apply rotor oil to the rotary valve through the slide receiver.
When to use slide cream and when to use slide oil
Slide cream and slide oil both allow the slide to move more smoothly. Which to use is up to personal preference. The condition of your instrument and the amount of cream or oil applied to it can also change how it feels to play, so it behooves you to discover what amount you feel most comfortable with. Incidentally, Yamaha slide oil contains an anti-rust agent to prevent the inside of the slide from rusting.
How much slide cream to apply
As a rule of thumb, you should apply only enough cream that the slide is still visible beneath it.
If the slide becomes sluggish 10 to 15 minutes after you start playing, you should have the slide checked at the shop.
If the slide is dirty the slide oil won't be able to lubricate it well. Prior to applying slide oil, be sure to thoroughly clean any dirt or moisture from the outside of the inner slide and the inside of the outer slide. Be careful however not to apply any unreasonable force on the slides when doing so.
Cleaning the slide
What to do if the plating is peeling
If the paint (or plating) is peeling, you may notice copper rust (green-colored rust) on the bare metal surfaces of the instrument. Although you can remove it by polishing the instrument with a metal polish, if the rust forms on a part of the instrument that is often touched when playing it, you should have the instrument repainted (or re-plated) at the shop.
