The distinction between cleaning and disinfection is crucial in infection prevention and control. Cleaning involves the physical removal of dirt, debris, and organic matter from surfaces. This process is essential because it prepares surfaces for subsequent disinfection. If surfaces are not adequately cleaned, the presence of organic matter can hinder the efficacy of disinfectants by shielding pathogens from the active ingredients intended to reduce their presence.

Disinfection, on the other hand, refers to the process that eliminates or inactivates most pathogens on surfaces, but it does not necessarily destroy all microorganisms, especially resistant spores. Effective disinfection relies on properly cleaned surfaces to ensure that the disinfectant can interact with the pathogens effectively.

Together, these two processes create a comprehensive approach to maintaining a safe and sanitary environment, particularly in healthcare settings where the risk of infection is a significant concern. Understanding this distinction helps ensure proper protocols are followed in infection control practices.
