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.

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 direc-
tion of the airow. If water is run through
the instrument from the leadpipe, dirt can
become clogged in the valves causing the
valves to become sluggish.

piece out with clean water.
