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?

You’re getting ride of more chemicals and germs properly washing your hands with soap and water anyway, so in this situation it wouldn’t really matter….
Sanitizers must be completely dry for them to have reached full efficacy. They don’t remove heavy chemicals like pesticides or metals.
Only actually washing your hands (the movement) plus soap does that.
