Care of Your Rental Trombone

Congratulations on choosing the trombone! We're excited for you to start on your musical journey! Here are some tips to help you take care of the trombone. If you have any other questions or concerns, visit our shop and speak to a technician! We'll be happy to help you out.


  • The slide portion of the trombone should smoothly, and without stopping, travel from all the way in to all the way out. If this is not the case, bring the instrument to Tim's Music for service.
  • The slide portion should be held by the two short metal braces connecting the slide tubes, not by the slide tubes themselves.
  • The slide portion consists of two pieces: the inner slide tubes and the outer slide tubes. When the two pieces are not connected, there is only one point of support on the inner slide tubes, so it is very easy for the inner slides to be knocked out of straight. Unless the instrument is being played or cleaned, the two pieces should be all the way nested and in the case.
  • Tim's Music will pull stuck mouthpieces for free. Please do not attempt to remove stuck mouthpieces on your own.
  • Once every four to six weeks, with adult supervision, the instrument should be given a bath: Fill bathtub with lukewarm water and a little dish soap. Separate the inner and outer slides (see above) and submerge components (including bell portion) in the soapy water. Use a trombone snake (sold at Tim's Music) to brush out the inner and outer slides and the smaller side of the bell section. Rinse off the whole instrument, allow some time to air dry after removing excess moisture, then re-lubricate and reassemble.
