Disinfection is the process by which a surface, object or substance is made free from disease-causing microorganisms. A disinfectant is any chemical that can kill these microorganisms. Disinfectants are commonly used in healthcare settings to reduce the risk of infection and increase patient safety, and they are also widely used in industry (e.g., food processing) as well as for cleaning both indoors and outdoors.
Disinfection is one form of a broader concept known as sanitization. Sanitizing means to reduce levels of dirt or contamination on an object.
