The cleaning of medical equipment typically involves three primary processes:
1. Cleaning: The physical removal of dirt and organic material using water and detergents. This is the essential first step before any further disinfection or sterilization. 2. Disinfection: The elimination of most pathogenic microorganisms, except [bacterial spores](), on inanimate objects. Disinfection can be achieved using chemical disinfectants or thermal methods. 3. Sterilization: The complete eradication of all forms of microbial life, including [spores](). Sterilization methods include steam under pressure (autoclaving), dry heat, ethylene oxide gas, and chemical sterilants.
