Sterilization

The complete destruction of all microbial life, including bacterial spores, usually achieved with an autoclave using high-pressure steam. It is required for items that may contact broken skin or blood.

Related: Disinfection, Autoclave
EPA-Registered Disinfectant

A chemical germicide carrying an Environmental Protection Agency registration number on its label, meaning it has been shown to kill specified organisms when used exactly as directed. Hospital-strength products are typically used in salons for implement disinfection.
