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?
