Your first-line-of-defense against Preventing the Corrosion of Surgical Instruments is the passive oxide layer of Surgical Instruments.
Stainless steel surgical instruments are made of corrosion resistant high-grade specialty steels. The keyword is “resistant”. Corrosion resistant does not mean corrosion proof. One of the special characteristics of these surgical instrument steels is that the manufacturer forms a "passive oxide layer" on the surface of surgical instruments which protects them against corrosion. This makes surgical instruments as corrosion resistant as possible. It is imperative that you maintain the passive oxide layer to prevent corrosion and maintain your surgical instruments in optimal condition. If this is not done the stainless steel will be more susceptible to corrosion, pitting and stains.This will reduce the life of the surgical instruments and/or render surgical instruments useless. Initially, all “stainless steel” surgical instruments have the same corrosion resistance. When strength and hardness requirements are important factors for instrument function, corrosion resistance is generally lower. Increasing the corrosion resistance softens the stainless steel. Manufacturers of surgical instruments and surgical instrument containers recommend the use of neutral pH Surgical Instrument Cleaners. Newly developed neutral pH all-in-one or "combination detergent" Surgical Instrument Cleaners have been shown to be effective in optimizing the efficacy of the "passive oxide layer". This will provide a longer life for stainless steel surgical instruments. Surgical Instrument Cleaners with a high or low pH have been shown to erode the passive layer. The most common of these surgical instrument cleaning concentrates utilize an alkaline detergent with an acid neutralizer. All manufacturers of surgical instruments and surgical instrument containers recommend against using these detergents and recommend using neutral ph Surgical Instrument Cleaner. More information and studies regarding the "passive oxide layer" of Surgical Instruments and the value of using a neutral ph Surgical Instrument Cleaner is below.

Interpreting "Rust" (Yellow-brown to Dark-brown Stains or Spots) when Cleaning Surgical Instruments and Cleaning Endoscopes.
Yellow-brown to dark-brown stains or spots on surgical stainless steel instruments are frequently mistaken for "rust". These residue deposits (stains or spots arranged in groups or along edges or in crevices) are usually the instrument being exposed to result of high chloride content. They will lead to pitting of the surgical instrument surface if not removed. (see Avoiding High Levels of Chloride below) Excessively hard water can contain high levels of salt sufficient to cause stains or spots that appear as rust. Boilers used to generate the steam for steam sterilizers, if not cleaned properly, will produce contaminated steam which can deposit minerals onto instruments during the sterilization process. Some Surgical Instrument Cleaners contain agents to soften hard water and eliminate spotting.
Avoiding High Levels of Chloride
- use neutral pH Surgical Instrument Cleaners
- dry and cool instruments as soon as possible following cleaning & sterilization treatments
- whenever possible use purified water (DI or RO) to thoroughly rinse instruments prior to drying & sterilization
- avoid exposing the surface protective layer of the instrument to abrasive conditions & treatments
- minimize the time instruments are exposed to high temperatures
- avoid using agents containing chloride (do not exceed ~ 120 mg/l, 200mg/l NaCl Sodium Chloride - Salt). A common problem is the inadvertent use of NaCl Sodium Chloride - Salt containing solutions do 'soaking instruments in surgery to maintain hydration of debris and prevent encrustation.
ALSO AVOID using Surgical Instrument Cleaners containing other halogen ion agents (e.g. iodides, bromides).
Use Surgical Instrument Cleaners containing "Nonionic Surfactants" whenever possible.
Neutral pH Surgical Instrument Cleaners are recommended by the Manufacturers of Surgical Instruments
Virtually all manufacturers of surgical instruments, rigid scopes, flexible scopes, and instrument containers recommend the use of a neutral pH Surgical Instrument Cleaner. Generic Example of this recommendation: "Do not use high acidic (pH <4) or high alkaline (pH >10) products for disinfection or cleaning, since these can corrode metal, cause discoloration or stress fractures."
Do not use abrasive pads or an abrasive Surgical Instrument Cleaner , which will scratch the surface allowing dirt and water deposits to collect. Abrasive cleaning will remove the protective passive layer.
Do not use a Surgical Instrument Cleaner 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 surgical instruments by similar metal for subsequent processing so that electrolytic deposition (galvanic corrosion) due to contact between dissimilar metals will not occur.

Surgical Instrument Washer Rinsing Instruments -
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.
Surgical Instrument Washer Cleaning, Conditioning, Disinfection & Sterilization of Surgical Instruments when Cleaning Surgical Instruments and Cleaning Endoscopes
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 surgical instruments. If cleaning must be delayed, place groups of surgical 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 surgical instruments and render higher quality cleaning outcomes. After surgery, open all surgical instrument box locks and disassemble surgical instruments with removable parts. This will limit blood drying on surgical instruments that may cause surgical instruments 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 surgical instrument corrosion, clean the surface of surgical instruments, and condition the surface of surgical instruments & scopes. This can significantly reduce manual cleaning and facilitate cleaning the surface of surgical instruments, scopes, and the lumens of cannulated surgical 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 surgical instruments and scopes inside-and-out. They effectively clean the surface of surgical instruments while cleaning lumens and working channels. This can eliminate or reduce the manual labor expended, rendering lower surgical instrument reprocessing costs while improving surgical instrument turnaround.
Surgical Instrument Washer is the Prerequisite for Sterilization
The reprocessing decontamination process, whether done manually or automatically in surgical instrument washers decontaminators disinfectors, will be effective if pre-cleaning is adequate. Presoaking with neutral pH enzymatic detergent surgical instrument cleaners will effectively remove debris and has proven to be an acceptable alternative to manually cleaning surgical instruments. During cleaning all surfaces of surgical instruments must be exposed to the cleaning process. The use of automated surgical instrument washers may reduce the risk of exposure to contaminants, improve turnaround time, and extend the life of surgical instruments. Delicate surgical instruments may be washed manually. Surgical instrument washer decontaminator racks have been designed to safely clean surgical instruments, including delicate surgical instruments and cannulated eye surgical instruments. These Surgical instrument Washer Racks clean the surgical instruments inside and out thereby eliminating the need for manually cleaning cannulated surgical instruments.
Sterilizing surgical instruments that are inadequately cleaned instrument is not possible. Cleaning surgical instruments is the prerequisite for sterilizing surgical instruments.
Ultrasonic Cleaning with a Surgical Instrument Washer when Cleaning Surgical Instruments and Cleaning scopes
Ultrasonic cleaners are more effective when used with hot water, as per the manufacturer’s recommended temperature.
It is recommended that all visible debris and blood be removed from the instrument prior to ultrasonic cleaning. Sort instruments by similar metals to prevent corrosion due to the contact of dissimilar metals. (electrolytic deposition - galvanic corrosion) It is not recommended to clean plated instruments in an ultrasonic cleaner since the ultrasonic vibration and the presence of other sharp instruments may crack or rupture the plating. Because Ultrasonic Cleaners do not provide the complete "proper sequence of treatments" i.e. final rinse(s) that are purified, purged between treatments, and/or have temperatures elevated to disinfection levels, they are not considered to be as clinically effective as automated surgical instrument washers. Ultrasonic Cleaning can effectively remove: long term encrustation and surgical cements or glues that have dried onto instrumentation.
Always refer to the printed manufacturer recommendations prior to using Ultrasonic Cleaning.
Recommendations for Maximizing the efficacy of Ultrasonic Cleaning:
• surgical instruments being cleaned must be fully immersed
• hinged surgical instruments must remain open during treatment
• only use cleaning trays that do not obstruct the ultrasonic cleaning process or add mass (e.g. wire baskets)
• large surface bulky items such as kidney shaped bowls must be positioned not to create anechoic (shadow) zones that will block the efficacy of ultrasonic transducer waveform. Position such items vertically or put them on top of the other items.
• always sort surgical instruments by similar metals to prevent corrosion
• do not overload the ultrasonic cleaning tank with excessive mass as this will reduce the efficacy of cleaning
• the soil being removed from surgical instruments being cleaned adds to the mass within the tank and decreases the efficacy of the ultrasonic cleaner. Review the level of soil and renew the ultrasonic bath as needed
• ALWAYS follow ultrasonic cleaning with separate rinse treatments. Ultrasonic cleaning will fragment and loosen soil but will not necessarily remove the soil from the surface of the surgical instruments being cleaned.
Cleaning Surgical Instruments prevents corrosion.
Surgical Instrument Washer Lubrication when Cleaning Surgical Instruments
To maintain moving parts and protect surgical instruments from staining and rusting during sterilization and storage, surgical instruments should be lubricated with a water-soluble, preserved lubricant after each cleaning. Most automated surgical instrument washers 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. The lubricant should contain a chemical preservative to prevent bacterial growth in the lubricant bath. The bath solution should be made with de-mineralized water. A surgical instrument lubricant containing a rust inhibitor helps prevent electrolytic corrosion of points and edges of surgical instruments. Immediately after cleaning, surgical instrument should be immersed or rinsed for 30 seconds and allowed to drain off, not wiped off. A lubricant film will remain through the sterilization to protect surgical instrument during storage.
Surgical Instrument Washer Prevent Staining and Spotting when Cleaning Surgical Instruments and Cleaning scopes
Staining and spotting may result if residual chemicals are not completely rinsed from surgical 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 on surgical instruments. A Surgical Instrument Cleaner that will avoid spotting is called "free-rinsing" or "rinse clean".
