Locate the main shutoff valve on your irrigation system. It is between the main water supply to your home and the sprinkler controller. Alternately, the main shutoff is located outdoors near a faucet bib. The main valve may be in a box in this area to protect it from the elements.
If manual cleaning is not performed immediately, instruments should be placed into a container and soaked with a detergent, a disinfectant/detergent, or an enzymatic cleaner to prevent drying of patient material and make manual cleaning easier and less time consuming.
Clean the valves with water at first too, to remove all of the gunk. Meanwhile you should BOIL the mouthpiece. Use a rag to get into the small cracks and crevices. Run a snake, that the music store will also sell, through all of the tubing until it comes out clean. let the valves dry seperately in a clean dry cup so that they wouldn't get lint on them. When putting it back together I would put the tuning slide grease on all of the tubes before reassembly. Then use the valve oil to put oil on the valves.
