Twice Yearly Maintenance
Cleaning the instrument
1.
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.
2.
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.
3.
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
1.
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.
