The primary purpose of a surgical instrument cleaner is to remove all inorganic and organic proteinaceous bioburden material from the internal and external surfaces cleaning surgical instruments inside and out with careful attention to cleaning cannulated surgical instruments.The secondary purpose of a surgical instrument cleaner is to maintain and improve the passive Layer of surgical stainless steel. The passive layer is provided by the manufacturer of the surgical instruments, within the surgical stainless steel, to resist prevent corrosion. The surgical instrument cleaner should be designed to maintain and improve this passive layer. For information go to: Prevent Surgical Instrument Corrosion. If the use of surgical instrument cleaners,the manual cleaning, brushing, and rinsing steps are not properly carried out, protein debris can harden and lead to formation of biofilm on the surgical instrument. The optimal surgical instrument cleaning protocol will break down proteinaceous bioburden and clean the surface. Inadequate cleaning can result in material remaining on the surgical instrument which will prevent disinfection and sterilization fluids or gases reaching all parts of the potentially contaminated device. Inadequate sterilization or disinfection sterilization and may in turn result in transmission of infectious organisms when the device is reused. The intricate design and delicate materials of flexible scopes complicate the cleaning process. This requires repetitive and consistent oversight.

Enzyme Surgical Instrument Cleaner Concentrates
Surgical Instrument cleaning Enzymes: Enzymes Surgical Instrument cleaning are costly, clinically and financially effective. Manufacturers of surgical instrument usually recommend that Enzyme Cleaning concentrates should be discarded after each use as these products are not microbicidal and will not retard microbial growth. Some manufactures of combination surgical instrument cleaning concentrates include a bacteriostatic agent which will prevent the growth of microorganisms. Some detergent complexes contain antimicrobial-microbicidal substances. Although these agents do not replace disinfection they are designed to reduce the risk of infection to reprocessing personnel by rendering instruments that are clean and safe to handle. The cleaning function efficacy of enzyme cleaning concentrates is determined by the ratio of enzymes to bioburden. The higher the proportion of enzymes the higher the efficacy. As a result, if the cleaning solution becomes laden with bioburden from previous cleaning, the efficacy of the enzyme cleaning concentrates is lower. When a cleaning concentrate states that is it "multi-tiered", the inference is that is contains: protease (enzyme) which break protein debris into smaller, more soluble subunits, amylase (enzyme) which catalyses the breakdown of starch, and lipase (enzyme) which breaks up fat-containing debris and carbohydrates. When a detergent cleaning concentrate states that is it high-level, the inference is that is contains a high concentration of enzymes. When a cleaning concentrate states that is provides enzyme activity the inference is that is contains enzymes but this is usually is a misrepresentation of ingredients for a detergent cleaning concentrate that does not contain enzymes. Enzymes are effective and they are costly for manufacturers to include in the formulation. As is true for all detergent cleaning concentrates, the most effective test is against your most difficult cleaning challenge. The two most common tests for cleaning concentration efficacy that are commercially available are the TOSI Test and the film test. Be aware that some manufacturers use advertising wordage and product names that imply enzymes are an active ingredient but do not actually include enzymes in their product formulation. Refer to product labels and ingredients for disclosure.

Optimal Temperature for Enzyme Surgical Instrument Cleaners
Enzyme cleaning concentrates function more effectively at temperatures above room temperature. The optimal range begins as > 22C - 72°F with performance reaching it's peak at 58.3C - 137F. This is often referred to as the optimal temperature for the performance or activity of enzymatic action. The activity of enzymes does not stop at higher temperatures but the level of performance does begin to decrease. Enzyme cleaning concentrates enzyme-detergents and all-in-one cleaning concentrates, which include enzymes, should be used in accordance with the manufacturer's recommendations and the recommendations of the medical devices being cleaned. Surgical Instrument Cleaners in the presence of pathological prions (Creutzfeld-Jakob disease) deactivating prions approach for cleaning surgical instruments can be the same if the presence of pathological prions (including the prions of vCJD Creutzfeld-Jakob disease) however the attention to detail is more important. It is known, that prions are unusually resistant to disinfection and sterilization by the physical and chemical methods used for decontamination of infectious pathogens. It is a difficult task to gain a consensus opinion on what constitutes optimal and practical conditions for decontamination of prions. Numerous studies have been conducted, but they do not reflect the reprocessing procedures for surgical instruments in a clinical setting. The clinical setting is critical for iatrogenic transmission, the passing of a disease from an infected individual or group to a previously uninfected individual or group. Disinfectants have been widely used for this purpose even although the disinfectants are ineffective. The most common practice believes that the only completely safe way to prevent transmission of vCJD is to use single-use surgical instruments. Because of the pervasive distribution of these infectious proteins and the long incubation time of the disease, reprocessing cleaning surgical instruments has been identified as a high risk factor for nosocomial transmission of vCJD. Research has shown that the agent of the vCJD disease, an infectious prion protein, is extremely resistant to today’s sterilization methods; therefore, the argument, It does not matter if instruments are 100 percent clean, as they will be sterilized, is definitely no longer valid. Today, we understand that cleaning surgical instruments is as important as the sterilizing the surgical instruments. Today’s surgical instrument cleaning process requires increasingly sophisticated surgical instrument cleaning concentrates. A number of hospitals and surgical centers are effectively using neutral pH combination enzymatic enzyme detergent cleaners for reprocessing surgical instruments. The combination enzyme detergent cleaners provide optimal cleaning as well as the highest possible level of care for surgical instruments and scopes. The manufacturers of surgical instruments strongly recommend the use of Neutral pH cleaners to enhance the passive layer of instrument protection. The early prion inactivation approach, using a high concentrate of sodium hydroxide solution or sodium hypochlorite combined with long holding times, is generally lethal for medical surgical instruments and washer-decontaminators- disinfectors. Recently, researchers have been looking is a minimally destructive method to decontaminate surgical instruments potentially contaminated with prions. The use of combination enzyme detergent surgical instrument cleaners has offered the highest level of cleaning outcomes. The ONEcleaner Enzyme Detergent Surgical Instrument Cleaners avoid corrosive stains, prevent stains, and remove surgical instrument stains.
