Your first-line-of-defense against Preventing Corrosion is the passive oxide layer of your Surgical Instruments. Stainless steel surgery instruments are made of corrosion resistant high-grade specialty steels. Surgical Instrument Cleaners with a high or low pH have been shown to erode the passive layer. The most common of these cleaning concentrates utilize an alkaline detergent with an acid neutralizer. Virtually all manufacturers of surgical instruments and surgical instrument containers recommend against using these detergents and recommend using a neutral ph Surgical Instrument Cleaner. More information and studies regarding the "passive oxide layer" of Surgical Instruments is below. Virtually all manufacturers of surgical instruments, rigid scopes, flexible scopes, and instrument containers recommend the use of neutral pH Surgical Instrument Cleaners. Do not use abrasive pads or abrasive Surgical Instrument Cleaners , which will scratch the surface allowing dirt and water deposits to collect. Abrasive cleaning will remove the protective passive layer. Do not use Surgical Instrument Cleaners with high concentrations of chlorine bleach to clean or disinfect stainless steel instruments, as pitting will occur. Never use bleach to clean any surgical instruments. The high pH of bleach causes surface deposits of brown stains and might even corrode the instrument. Even high quality stainless steel is not impervious to an acidic bleach solution.
Sort instruments by similar metal for subsequent processing so that electrolytic deposition (galvanic corrosion) due to contact between dissimilar metals will not occur.
Surgical Instrument Cleaning Tap water can contain many minerals, which may discolor and stain surgical instruments. It is recommended that de-ionized water be used for the final rinsing to prevent spotting. all-in-one or "combination" Surgical Instrument Cleaners can be effective in treating unacceptably hard source water and removing hard water encrustation from surgical instruments and equipment. If untreated tap water is used for final rinsing, then the instruments must be dried immediately to avoid staining. Clean instruments, or apply treatment to prevent the drying and encrustation of debris, as quickly as possible after use. Do not allow blood and debris to dry on the instruments. If cleaning must be delayed, place groups of instruments in a covered container with appropriate enzyme-detergent Surgical Instrument Cleaners or apply an enzyme-detergent foam spray to delay drying. The use of pre-soaking enzyme-detergent Surgical Instrument Cleaners have been shown to reduce the time expended for manual cleaning and render higher quality outcomes. After surgery, open all box locks and disassemble instruments with removable parts. This will limit blood drying on instruments that may cause them to corrode. The "all-in-one" Surgical Instrument Cleaners and the enzyme-detergent Surgical Instrument Cleaners deliver a chemical complex to: maintain the hydration of bioburden, prevent corrosion, clean the surface, and condition the surface of instruments & scopes. This can significantly reduce manual cleaning and facilitate cleaning the surface of surgical instruments, scopes, and the lumens of cannulated instruments inside-and-one. If used properly, all-in-one enzyme detergent Surgical Instrument Cleaners and/or all-in-one "combination" Surgical Instrument Cleanerss can render excellent outcomes and facilitate cleaning instruments and scopes inside-and-out. They effectively cleaning the surface while cleaning lumens and working channels. This can eliminate or reduce the manual labor expended, rendering lower reprocessing costs while improving turnaround. Ultrasonic cleaners are very effective when used with hot water per manufacturer’s recommended temperature and specially formulated detergents. It is recommended that all visible debris and blood be removed from the instrument prior to ultrasonic cleaning. Contact between dissimilar metals can cause corrosion when ultrasonic cleaning is applied. Sort surgical instruments according to similar metal types to prevent corrosion. (electrolytic deposition - galvanic corrosion) It is not recommended to clean plated instruments in an ultrasonic cleaner since the ultrasonic cleaner vibration and the presence of other sharp surgery instruments may crack or rupture the plating. Ultrasonic Cleaners do not provide the complete "proper sequence of treatments" i.e. purified final rinse(s) that are purified, purged between treatments and/or have temperatures elevated to disinfection levels. Ultrasonic Cleaning can effectively remove: long term encrustation and surgical cements or glues that have dried onto instrumentation. Overloading, and low water temperature, will decrease the effectiveness of ultrasonic cleaner equipment. To maintain moving parts and protect instruments from staining and rusting during sterilization and storage, they should be lubricated with a water-soluble, preserved lubricant after each cleaning. Most automated washer decontaminators provide the option for lubrication at the end of the final rinse treatment. Since effective ultrasonic cleaning removes all lubricant, re-lubrication is important. "all-in-one" Surgical Instrument Cleaners will provide lubrication. A lubricant film will remain through the sterilization to protect surgery instruments during storage. Surgical Instrument Washer Prevent Staining and Spotting when Cleaning Surgical Instrument Cleaning Staining and spotting may result if residual chemicals are not completely rinsed from surgery instruments that are subjected to steam sterilization. Following the manufacturer’s recommendations for the proper sequence of treatments (cold water pre-wash, enzyme-detergent wash, purified water rinse/lubrication, and drying) is critical to prevent stains and spots. The use of Surgical Instrument Cleaners that deliver an acid rinse will release nickel from the stainless steel and decrease the efficacy of the passive layer. This is most critical on initial reprocessing events of stainless steel surgical instruments. Measurable levels of nickel have been detected. It was also shown that, as the number of subsequent uses increased, the level of nickel release diminished and reached a steady state (measured in the order of μg/l). These observations reflect the changes that occur in the passive oxide layer on first immersion of stainless steels in aqueous media. What is a Stainless Steel Surgical Instrument? Stainless steel is essentially a low carbon steel which contains chromium at 10% or more by weight. It is this addition of chromium that gives the steel its unique stainless, corrosion resisting properties.
UPS-1 Surgical Instrument Enzyme Detergent Lubricant Cleaners
are highly concentrated for lower surgical instrument cleaning costs. Surgical Instrument Enzyme Cleaners remove stains. ONE gallon of the ergo-Logistics Surgical Instrument Enzyme Cleaner delivers 512 gallons of Surgical Instrument Enzyme Cleaning that removes stains, conditions, and lubricates instruments.
