Care and Maintenance of a Trombone
Cleaning small parts

  1. Prepare a brass soap water solution. Mix 1 part brass soap with between 10 and 15 parts warm water (30°C to 40°C).
  2. Apply the solution to a flexible cleaner brush and use it to clean the inside of the instrument.
  3. After cleaning the instrument, rinse out the brass soap with water. Use some gauze to completely dry the instrument, then apply some slide grease (or slide oil) to the slide, and apply some slide grease to the tuning slide.
