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.
Rinse and dry the instruments. After cleaning the instruments, rinse them for 30 seconds. Place them on a clean towel and allow them to thoroughly dry. Instruments must be dry and free from mineral deposits because such substances may cause damage to the instruments or sterilizer. Again, cleaning the instruments is not meant to sterilize them.
