■ Twice Yearly Maintenance

●

Cleaning the instrument

Make a brass soap water solution.

Prepare a brass soap water solution using

between 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

casing parts, and slide valves.

With the instrument removed from the wa-

ter, apply some soap water solution to a flex-

ible 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 moisture 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

rinsing the pipes with water, run water

through tuning slides in the opposite di-

rection of the airflow. If water is run

through the instrument 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

mouthpiece out with clean water.
