Cleaning Surgical Instruments properly can avoid corrosion. Surgical Instrument Cleaning Detergents, and Enzyme Detergent Lubricants for cleaning Surgical Instruments enhance the Prerequisite for Sterilization. It is imperative that you maintain the passive oxide layer to prevent corrosion and maintain your surgery 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 surgery instruments and/or render it 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 would soften the stainless steel. Manufacturers of surgery instruments and surgical instrument containers recommend the use of neutral pH cleaning concentrates. Newly developed neutral pH all-in-one or combination enzyme detergent surgical instrument cleaning detergents have been shown to be effective in optimizing the efficacy of the passive oxide layer. This will provide a longer life for stainless steel surgery instruments. Cleaning concentrates with a high or low pH have been shown to erode the passive layer. The all-in-ONE enzyme detergent lubricating surgical instrument cleaners will lower cleaning costs, replace multiple surgical instrument cleaner products and provide an excellent endoscope cleaner.

The combination cleaning concentrates 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. Apply cleaning treatments to prevent the drying and encrustation of debris, as quickly as possible after use.
Cleaning the Prerequisite for Sterilization
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 Ultrasonics is applied. Ultrasonic cleaners are most effective when used with hot water per manufacturer’s recommended temperature and with enzyme detergents. It is recommended that all visible debris and blood be removed from the instrument prior to ultrasonic cleaning. Always refer to the printed manufacturer recommendations prior to using Ultrasonics. Lubrication of Surgical Instruments 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. 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 lubricant containing a rust inhibitor helps prevent electrolytic corrosion of points and edges. Immediately after cleaning, instruments should be immersed or rinsed for 30 seconds and allowed to drain off, not wiped off. When using surgical instrument cleaning solutions staining and spotting may result if residual chemicals are not completely rinsed from surgery instruments that are subjected to steam sterilization. The use of cleaning concentrates that deliver an acid rinse will release nickel from the stainless steel and decrease the efficacy of the passive layer. 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? The chromium content of the steel allows the formation of a rough, adherent, invisible, corrosion-resisting chromium oxide film on the steel surface. If damaged mechanically or chemically, this film is self-healing, providing that oxygen, even in very small amounts, is present. The corrosion resistance and other useful properties of the steel are enhanced by increased chromium content and the addition of other elements such as molybdenum, nickel and nitrogen. Stainless steel has a passive film created by the presence of chromium (and often other alloying elements, nickel, molybdenum) that resists this process. When exposed in air, stainless steels passivate naturally (due to the presence of chromium). How is the passive oxide layer Manufactured and Maintained? The passive layer or stainless steel is intended to prevent or resist corrosion. The process is called Passivation. Passivation eliminates the carbon molecules form the instrument surface. This forms a layer which acts as a corrosive resistant seal. Passivation is a chemical process that removes carbon molecules from the surface of the instrument. This chemical process can also occur through repeated exposure to oxidizing agents in chemicals, soaps, and the atmosphere. Polishing, by the manufacturer, is a process used to achieve a smooth surface on the instrument. Surgical Instruments are polished because the passivation process leaves microscopic pits where the carbon molecules were removed. In some circumstances older instruments have higher resistance to corrosion than new ones. The newer instruments have not had the time to build up the chromium oxide layer. Improper cleaning and sterilization can cause the layer of chromium oxide to disappear or become damaged thus increasing the possibility of corrosion and/or pitting.
