Hu-Friedy Cleaning Monitors

The First Step to Proper Instrument Reprocessing

Proper cleaning is the first and most important step to effective Instrument Reprocessing. Visibly clean instruments might not be enough to ensure quality of your cleaning protocol. Wouldn’t you want to know if your instruments have passed the first step?

Hu-Friedy Cleaning Monitors are designed to monitor the efficacy of the cleaning process when using washer-disinfectors and ultrasonic cleaners. The monitors contain a non-toxic test soil that mimics the presence of blood and tissue on an instrument surface. Full removal the test soil indicates an effective cleaning process.

How Do Cleaning Monitors Work?

Until Hu-Friedy Cleaning Monitors, no other tests or methods existed in the dental industry that measured multiple parameters to your cleaning process. Have you considered all the factors of an efficient cleaning cycle?

How it works:

  • Insert single use Cleaning Monitor strip into the holder
  • Place holder with strip face up in equipment:
  • Run cleaning cycle
  • Review results of Cleaning Monitor to determine if adjustments to process are needed


Washer-Disinfector Ultrasonic
  • Time
  • Cavitation
  • Temperature
  • Time
  • Detergent concentration
  • Temperature
  • Spray arm function
  • Detergent Amount
  • Enzyme soak
  • Number of Instruments

Why Would My Process Fail?

There are many things that can affect the quality of your cleaning protocol. Rather than assuming that your instruments are clean just by looking at them, let’s consider some of the common process failures for your Washer-Disinfector or Ultrasonic Cleaner.


Washer-Disinfector Ultrasonic
  • Inadequate water spray/impingement
  • Ineffective cavitation
  • Clogged spray arms
  • Overloading
  • Overloading
  • Insufficient time, temperature and/or detergent
  • Instrument shadowing
  • Inadequate detergent dosing
  • Improper detergent dosing

When do you use Cleaning Monitors?

Run a monitor test in the morning to release the equipment for use and minimum of one monitor per load for load release.

Monitor once daily with an empty load for a machine release and periodically throughout the day with instruments for a load release, if needed.

Who Should Use Cleaning Monitors?

Proper infection control is the responsibility of all office team members, especially if you are the designated Infection Control Coordinator. Adding additional safeguards to your cleaning and sterilization protocols will help increase office efficiency and ensure proper instrument reprocessing.
