How to Sterilize Stainless Steel

Stainless steel is a label used for a group of metal alloys that contain at least 10.5 percent chromium. Since stainless steel is durable, easy to clean and resistant to corrosion, it is used for a wide variety of purposes. You may see stainless steel on items such as appliances, cookware, bottles, trays, pipes, medical instruments and tools. It is important to sterilize certain stainless steel surfaces in order to remove any bacteria or viruses that may be present. Sterilization, which is the removal of all living organisms, is even more comprehensive than regular cleaning or sanitation.
