If a tuba is played at least an hour per day, never in a smoky environment, never immediately after eating, how often should it be ultrasonically or chemically cleaned?
If that same tuba appears to be performing properly in all respects, and is periodically
�bathtub cleaned� with brushes, etc., should it be ultrasonally or chemically cleaned at all?
