Trombone/Maintaining the Instrument

Cleaning Your Horn Whenever you notice that your trombone is excessively dirty, (at least once every two months, depending on amount of use), you should wash your Trombone. To wash the Trombone, you should place the trombone, one piece at a time in a bathtub full of warm soapy water. You should gently scrub it with a soft rag, soaked in the water. Whenever about to go to a concert, competition, or other important event, you should polish the horn with silver polish if the horn is silver, if the horn is brass, you should rinse the dirt off with a wet rag.
