How to Clean the Autoclave

The autoclave needed to be cleaned this morning, and since I had to scrounge around for the manual to find the procedure on how to do this, I decided to include the cleaning procedure on the wiki in my notebook. Now, I fully acknowledge that the majority of this procedure is not my own, and that I borrowed heavily from the manual for our Tuttnauer autoclave even copying some portions verbatim, with some additions of my own. However, with the realization that we don't have a procedure on the wiki I am copying it to the wiki. I will later link this page to the procedure page and visa verse.

How to clean the autoclave:

  • Important, while you are cleaning the autoclave follow these steps without interruption. An interruption would not clean the autoclave effectively and waste your time.


  1. When the autoclave chamber is cold, remove instruments and trays from the autoclave. It is a good idea to just put them on top of the autoclave where you know where they've been.
  2. Open the door and spread the contents of a packet of the cleaner, Chamber Brite Autoclave Cleaner, in a straight even line along the bottom of the chamber, from back to front.
  3. Start a sterilization cycle with water and no drying cycle. To do this:
    • Turn green switch to "Start"
    • Turn the bottom nob to "Fill Water"
    • Wait until the water reaches the lip towards the front of the autoclave.
    • Turn the bottom nob to "STE" for sterilization and close the door.
    • Set the temperature to 273°F (134°C) and the timer to 30 mins.
    • The timer will ding after the cycle has ran to completion, at this point you do not want to dry the "samples" so:
    • Immediately turn the bottom nob to "EXH+DRY" and wait for the pressure to reach 0 psi.
    • Turn the bottom nob to "0" and open the door slowly to release pressure.
  4. Drain the water out of the reservoir with by turning the valve on the lower left corner of the interior of the door counter-clockwise to the open position. Turn it clockwise to the closed position when you are done.
  5. Replace the water in the reservoir with DI water.
  6. Repeat the sterilization process from step 3 again. This time do not use any of the cleaner.
  7. Drain the water from the reservoir again.
  8. Turn the autoclave off and allow the chamber to cool.
  9. Remove the tray holder; wipe the interior of the chamber with a damp cloth.
  10. Fill the reservoir again with DI water.
  11. Turn the fill knob to the fill position. Allow a small amount of water to fill in, enough to ensure that it is working. Remove the water, and the autoclave is good to go.

This process, without my notes, is included on the inside of the top flap of the box containing the cleaner. It can also be found on page 28 of the manual for the autoclave.
