Usage Tips: How to lubricate the trombone
slide
To use, just put a drop or two on the ends of each slide (the
stockings, where the slide gets a little larger) and work it in by
moving the slide back and forth a few times. Then put a drop or two
on the upper ends of the slides and work it in again. Mist with a
little water if desired.

Ultra-Pure Trombone Slide Lube has the perfect balance of speed,
smoothness, and endurance. It goes on easily and does not build up.
It does not separate under hot or freezing conditions. A few
drops on each stocking and a few drops on the upper part of the
slide is all you will need for several days of playing.
