What is a sanitize?

According to EPA specifications, a sanitizer is a type of antimicrobial that kills or irreversibly inactivates at least 99.9 percent of all fungi, bacteria, and viruses (otherwise known as called microbes or microorganisms) present on a surface. Most sanitizers contain toxic chemicals such as iodine, chlorine, phenol, or quaternary ammonium compounds, and opposed to some antiseptics, should never be taken internally.
