Much of the conversation around medical device cleanliness is about sanitation and sterilization. While both are important for eliminating potentially harmful microorganisms, medical devices also need to be cleaned prior to sterilization.
The purpose of cleaning medical devices prior to sterilization is to remove particulates and fluids that may have accumulated during machining and assembly. For devices made of stainless steel and titanium, such as joint implants, metal shavings can be stuck in holes or connecting points. Additionally, the oil used to cut and shape the implants must be removed prior to the next steps of production. These products will often be cleaned multiple times during assembly and before the product is sterilized.
