To be effective, a hand-sanitizer must contain at least 60 percent alcohol, according to the Mayo Clinic. When using sanitizer, apply enough gel to wet your hands thoroughly, and rub them together for about 25 seconds, or until the gel is dry. If your hands are visibly dirty, you should use soap and water instead of hand-sanitizer.
