The process used to wash and remove blood and tissue from medical instruments is known as cleaning. Cleaning is the first step in maintaining the sterility and functionality of medical instruments. It involves the physical removal of debris, including blood and tissue, from instruments using soap, detergents, and water. Proper cleaning is crucial because any residual organic matter can hinder subsequent disinfection or sterilization processes.

While sanitation, sterilization, and disinfection are related processes in infection control, they serve different purposes. Sanitation typically refers to reducing the number of microorganisms to safe levels, often in non-medical contexts. Sterilization is the complete elimination of all microorganisms, including spores, usually achieved through methods like autoclaving or chemical sterilants. Disinfection reduces the number of viable bacteria but does not necessarily kill spores and is often used on surfaces rather than instruments.

Understanding the specific function and necessity of cleaning helps in maintaining a safe clinical environment and ensuring patient safety.
