 Twice Yearly Maintenance

 Cleaning the instrument

Make a brass soap water solution.

Prepare a brass soap water solution using be-

tween 10 to 15 parts warm water (30° C to

40° C) and 1 part brass soap.

Before putting the instrument into the soap

water solution, remove the pistons, valve cas-

ing parts, and slide valves.

With the instrument removed from the water,

apply some soap water solution to a flexible

cleaner and use the cleaner to clean the inside

of the instrument's pipes.

After cleaning the instrument, use clean water

to thoroughly rinse out the brass soap water

solution. After completely removing all mois-

ture with a gauze, apply oil and grease, and

then reassemble the instrument.

Maintenance

CAUTION! When cleaning the internal

parts on a rotary tuba.

Never dismantle the rotors. Also, when rins-

ing the pipes with water, run water through

tuning slides in the opposite direction of the

airflow. If water is run through the instru-

ment from the leadpipe, dirt can become

clogged in the valves causing the valves to

become sluggish.

 Cleaning the mouthpiece

Dip the mouthpiece brush in the brass soap

water solution and use the brush to clean the

throat of the mouthpiece. Rinse the mouth-

piece out with clean water.
