If you wash your hands with Purell, then wash your hands with soap and water 5 minutes afterwards, did you wash off/undo the Purell? Just wondering how long the Purell has to be on your hands to kill the germs. Is it possible to wash it off?

There’s another post where a teacher did an experiement with slices of bread in a ziplock bag and each one was like “touched after touching chromebook” “not touched” “touched after washing hands” “touched with unwashed hands” and “touched after using hand sanitizer” and it showed some really gnarly stuff for the sanitizer. Would not recommend. Just use soap and water
