Proper Sequence of Surgical Instrument 
Washer Disinfector Cycle Temperature Treatments

Washer Disinfectors Properly Designed Deliver Safe Surgical Instruments delivering the proper sequence of washer treatments. The Proper Sequence of Surgical Instrument Washer Disinfector Treatments will deliver consistently clean medical devices that are safe to handle and have received the prerequisite for sterilization.

The proper washer disinfector cycle temperatures are: 
Cold  Water Pre Wash Cycle: ambient to 95 F
Wash Enzymatic/Detergent Cycle: 131 F to 137 F
Elevated Thermal Rinse Cycles: 194º F to 209 F
Hot Air Dry Cycle: 158 F to 230 F

The ONEcleaner enzyme surgical instrument detergent cleaners are the most effective enzyme detergent cleaners available, delivering all the ingredients necessary for the highest quality cleaning outcomes.

 The ONEcleaner enzymatic surgical instrument cleaners lubricate while they clean faster and lower cleaning costs. ONEcleaner enzyme surgical instrument detergents clean strengthen the passive layer of protection against corrosion. The handling of each individual surgical instrument device is time consuming, labor intensive, renders limited through-put and has high overhead costs. In the United States manufacturers of Surgical Instrument Washers are not approved by the FDA to market their products as Washer Disinfectors. However, many of the Surgical Instrument Washers are manufactured to produce the times and temperatures that can effectively deliver disinfected surgical instruments. If it is your preference to have cleaning reprocessing results of a washer disinfector, refer to the Surgical Instrument Washer Specifications for assurance that the times and temperatures available are those you consider to be appropriate for disinfecting surgical instruments.

Surgical Instrument Washer Disinfectors can safely contain within their chambers the cleaning-decontamination-reprocessing functions, removal of debris, and contaminated aerosols. The batch treatment of reprocessing surgical instruments using automated Surgical Instrument Washer Disinfectors saves time, increases material through-put, improves surgical instrument turnaround times, provides for FTE reduction, and lowers cost for surgical instrument cleaners. It has been demonstrated that a properly designed Surgical Instrument Washer Disinfector, that is used to manufacturer’s specifications, will consistently and repeatedly remove all microorganisms from surgical instruments. 

Washer Disinfectors should be used in accordance with the manufacturer’s direction for use, to secure the most consistent and efficacious results. Worker safety and reprocessing efficacy can be compromised by violating the manufacturer’s recommendations. Examples of such recommendations are: Keeping the cannulated surgical instrument working chambers and lumens exposed during cleaning-reprocessing and the use of purified water final rinses. A Clean Surgical Instrument Device is Safe to Handle. It is critical that devices are cleaned properly to secure the safety of reprocessing workers in the Clean Area. During the steps of inspection, sorting and packaging of devices, the unprotected reprocessing personnel are repeatedly at risk from a surgical instrument that has remained contaminated with microorganisms. Within the implementation of the Universal Surgical Instrument Reprocessing Decontamination Precautions, it is our goal to eliminate exposure and reduce the risk to Reprocessing personnel whenever possible. The use of proper hand washing surgical instrument reprocessing decontamination methods can render surgical instruments that are clean, but requires the continual exposure of the Reprocessing Staff to contaminated surgical instruments. The Reprocessing Staff performance is influenced by skill level, knowledge and work load. This may impact the efficacy of the process. The use of a properly designed surgical instrument washer decontaminator disinfector reduces the: overhead cost of reprocessing, risks to the Reprocessing Staff and provides consistence removal of all microorganisms from soiled surgical instruments.  Once a surgical instrument is clean, it is then safe for further reprocessing and handling. Proper cleaning is the prerequisite for disinfecting and/or sterilizing surgical instruments.
