How much does an average hand sanatizer disinfect?

An average hand sanitizer typically contains between 60% to 95% alcohol, which is effective in killing most germs, including bacteria and viruses, on the skin. It can significantly reduce the number of pathogens on hands when used properly, usually requiring a sufficient amount to cover all surfaces and allowing it to dry completely. However, hand sanitizer is not as effective on visibly dirty or greasy hands, where soap and water are recommended instead. Overall, while it effectively disinfects, its efficacy can vary based on the formulation and application.
