Disinfection
Disinfectants are substances that are applied to non-living objects to destroy microorganisms that are living on the objects. Disinfection does not necessarily kill all microorganisms, especially non resistant bacterial spores; it is less effective than sterilization, which is an extreme physical and / or chemical process that kills all types of life. Disinfectants are different from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides - the latter are intended to destroy all forms of life, not just microorganisms.
Sanitisers are substances that simultaneously clean and disinfect.
Bacterial endospores are most resistant to disinfectants, but some viruses and bacteria also possess some tolerance.
Disinfectants are frequently used in hospitals, dental surgeries, kitchens, and bathrooms to kill infectious organisms.
