Does hand sanitizer kill all viruses?

Hand sanitizer is effective against many viruses, particularly enveloped viruses like the flu and coronaviruses, when it contains at least 60% alcohol. However, it does not kill all viruses, particularly non-enveloped viruses like norovirus and some strains of adenovirus, which are more resistant to alcohol-based sanitizers. Additionally, hand sanitizer may not eliminate all types of germs, especially if hands are visibly dirty or greasy. For comprehensive protection, washing hands with soap and water is recommended.
