Surgical Instrument Washer Sterilizer Detergents that lubricate while they clean boost reprocessing productivity. Surgical Instrument Washer Sterilizer Detergents that lubricate cut washing costs and wash faster. To be clear, surgical instrument washer sterilizers do not sterilize medical devices. They have, in fact, been replaced by decontaminators. It has been proven that washers sterilizers not only do not sterilize, but that they are ineffective for adequately cleaning surgical instruments prior to terminal sterilization. Enzymes alone do not clean surgical instruments. Surgical Instrument Detergents are necessary. Surgical Instrument Detergents are necessary to clean the surface of surgical instruments once enzymes have broken down bioburden. It is commonly stated that enzymes clean rapidly. Enzymes alone do not clean. The primary function of an enzyme surgical instrument detergent cleaner is to break down soil, usually proteinaceous bioburden. For a surgical instrument detergent cleaning product to clean, surfactant detergents are necessary that will remove the soil from the surface of the surgical instruments. A combination of enzymes and detergents are necessary for optimal cleaning. Enzyme detergent surgical instrument cleaners are often referred to as combination surgical instrument detergent enzyme cleaners. The use of enzymes of various compositions and concentrations, in enzyme surgical instrument detergent cleaners is becoming common. Over half of all surgical instrument detergents presently available contain some level of enzyme detergent. If designed properly, surgical instrument detergent enzyme cleaners can: remove proteinaceous bioburden from surgical instruments, dissolve mineral encrustation from surgical instruments, remove stains from surgical instruments, and enhance the passive layer of the surgical instrument stainless steel and lubricate surgical instruments.
