文摘

Cleaning reusable medical devices removes organic and inorganic soil, which allows for effective disinfection and sterilization. However, it is not always clear what variables to consider when validating cleaning. This study compared the ability of 3 different cleaning agents (ie, water, alcohol, and bleach) to remove bacteria (ie, vegetative and spores) and artificial blood test soil from 2 common device materials: polypropylene and ultra-high-molecular-weight polyethylene. There was a complex interaction between bacteria, soil, and surface roughness.
