Which statement about sterilization versus disinfection in salons is correct?

Sterilization destroys all microbial life, including bacterial spores, and is mainly used for medical instruments; it is rarely required for general salon services. Disinfection destroys most pathogens on nonporous surfaces and is the standard level of decontamination salons use for reusable implements after cleaning. The two are not the same, and disinfection (not sterilization) is what most salon rules require. Distinguishing these levels — and knowing the salon standard is clean-then-disinfect — is a frequently tested scientific-concepts point.
