Start of Day:

  • Fill Ultrasonic Cleaner with water and ultrasonic solution.
  • Degas the solution by running the ultrasonic cleaner for 5 minutes, prior to the first cleaning cycle.


  • Make sure that Personal Protective Equipment (PPE) is worn - gloves, eyewear and mask.
  • Visually inspect instruments for damage, dulling, etc.
  • Place loose instruments in cleaning basket. No more than 3 layers of instruments should be cleaned at a time. If using cassettes, load instruments into cassette and place cassettes into cassette rack. Whether cleaning loose instruments or using cassettes, do not rest items on the bottom of the tank.
  • Carefully lower the basket or rack into the ultrasonic cleaner and place cover over the tank. Set cleaning cycle on the timer and begin cleaning instruments.
  • Loose instruments should be cleaned for 6-12 minutes. Cassette cleaning cycle is 20 – 30 minutes. Consult the IFU for the ultrasonic cleaning solution. Some solutions have a minimum contact time for cleaning. Debris that has been allowed to dry on an instrument may extend the required cleaning cycle.
  • Remove basket/rack from the ultrasonic and inspect for debris on the instruments. Repeat cleaning if needed.
  • Rinse solution off the instruments with running water from the sink.
  • Dry instruments and prepare for sterilization.

End of Day:

  • Drain ultrasonic tank and rinse with water to remove residual detergents and debris.
  • If necessary, a mild, non-abrasive, non-acidic household cleaner may be used to wipe down the tank and exterior of the ultrasonic cleaner.
