QHR Sudser in action

Directions for cleaning your horn WITH the QHR Sudser:

Preparation: Required items: QHR Sudser, QHR, snake, towel or mat.

Connect the QHR Sudser to a standard ¾ inch hose, connect the adapter & QHR to the Sudser.
Load liquid soap into the soap canister and connect it to the Sudser.
Test the connection by turning on the water while holding the Sudser and QHR nozzle. Water should flow through the hose and out the nozzle.
For Large Brass instruments, remove the MAIN TUNING SLIDE FROM THE HORN.
If using a tub, put the horn into the tub.

Cleaning:

Using your flexible snake, wet the brush and snake the lead pipe to break loose any large particles of debris.
Insert the QHR nozzle into the lead pipe and gently turn on the water with the soap control in the ON position..
The water will force the cleaning solution through the horn.
Soapy water should begin flowing out the open horn through the main tuning slide connection or bell.
Push down first valve and soapy water will flow through the first vale slide tubing and back into the open horn.
Continue the process with all valve combinations (1, 12, 2, 23, 3, 13, 123). If the horn has a fourth valve, continue with all valve combinations using the fourth valve.
Turn off the Sudser and let the horn soak for a few minutes.
DO NOT allow excessive water pressure to force the tuning slides out of the horn as this could result in dents or damage to the slides.

Remove the QHR and snake the lead pipe again to break loose any additional debris.
Continue to flush the horn with the soapy water.
Turn OFF the soap and flush clear water through the horn. Continue to flush until clear water is flowing through the entire horn.
When clean water is flowing out the horn you are done with the QHR. Turn off the water and remove the QHR nozzle from the horn.
In some cases you may want to reverse the process and flush water through the tuning piping.

Finish:

Remove all the slides and pour the water from the horn and slides.
For Piston valves, remove the valves, oil them and replace. If necessary, brush the valve openings and rinse under the tap.
NOTE: For Rotary Valves, rotary valves should only be removed and replaced by qualified technicians.
Put slide grease on the slides and return them to the horn.
Dry it off and you are ready to play with a clean horn.
