This oil is in the tiny bottles in the basket of the Statim counter. This is the same oil we use to lubricate when we clean the handpieces. This will keep things from sticking in the nozzle itself.

J. Water bottles in operatories should be thoroughly flushed and rinsed with Clorox every night.

1. Clean and condition dental chairs and stools. Spray dental chairs and stools with dentophene solution. Leave on until dry.
2. Defrost and clean one refrigerator (alternating) each week.
3. Empty and clean central vacuum separator canisters in the carts in each operatory. To clean the central vacuum solid waste separator, first open the lid, and then pick up the bowl, empty the solid waste into the amalgam can in the C&S area. Then clean the screen by running it under hot water, then replace. Wear heavy yellow gloves while you are doing this maintenance. Extra suction traps are located in the storage closet.
4. Clean the autoclaves. Drain the old water from the autoclave through the drain hole on the bottom of the autoclave. Add cleaner with two quarts of tap water, and run autoclave for 20 minutes. Drain and add two quarts of distilled water and run for 15 minutes. Drain out completely until there are no more bubbles. Clean tray and tray holders with Jet Dri. Fill to line with distilled water.
5. Clean all operatories.
6. Clean the microwaves.
7. Clean exterior of all hoses
8. Clean light Fantastik Shield using only water.
9. Statim. There is a sensor probe at the inside back of the unit. If this probe is bent, we should never try to straighten it. This is very sensitive and can break easily and the whole unit would be totaled. We must make sure we push straight in and not at an angle. Remove the seal in the lid. Use Ivory soap on the seal and wipe soap on the seal and reinsert. This will dry and seal tight. An extra gasket seal is kept in the cabinet above the statim with the small bottle of soap.

Clean autoclave

1. Check N2O rubber goods for leaks with soap solution (spray bottle is in the room)
