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.
Likewise, alkaline detergents may leave surface deposits that cause a brown stain and interfere with the smooth operation of the instrument. Use soft plastic cleaning brushes to scrub the instruments. Do not use steel wool, wire brushes or other abrasive materials that could scratch the finish or dull your instruments. Hold the instruments below the surface of the water when you scrub them to avoid splattering contaminants.
