Enzyme Surgical Instrument Detergents improve the decontamination process. Your first-line-of-defense against corrosion is the passive oxide layer of surgical instruments. Stainless steel surgical instruments are made of corrosion resistant high-grade specialty steels.

One of the special characteristics of these steels is that the manufacturer forms a passive oxide layer on the surface, 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 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. Initially, all stainless steel surgical instruments have the same corrosion resistance.

Manufacturers of surgical instruments recommend the use of neutral pH enzyme detergent cleaners. Neutral pH all-in-one enzyme surgical instrument cleaner detergent concentrates 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 most common of these cleaning concentrates utilize an alkaline detergent with an acid neutralizer. A reduction in corrosion prevention will result from the use of cleaning concentrates that are not neutral pH. 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.
