How do you clean a trombone in 3 steps?

1. Dismantle the trombone. Remove the mouthpiece, slide, and bell from the main body of the instrument.

2. Clean the parts. Use a trombone cleaning kit to clean the inner and outer surfaces of the instrument. Be sure to clean the slide thoroughly, as this is where dirt and grime can build up.

3. Reassemble the trombone. Once the parts are clean, reassemble the instrument. Make sure that all of the parts are properly aligned before tightening the screws.
