I know this to be true, and wash my hands often. My son prefers hand sanitizer and will get annoyed when I ask him to wash his hands, despite me telling him its better than hand sanitizer. He asked me why and honestly, I dont know. Killing 99.9% of germs seems like pretty good odds but its something to do with the scrubbing motion, right?
In: Biology
If the sanitizer contains other chemicals besides volatile alcohol, they will remain on the skin and irritate the protective oil layer as the hand gets wet from sweat, and leave residue of soap and dead skin on clothing or bag handles. The sanitizer may kill living organisms, but doesn’t remove all grime that prompted you to clean the hands in the first place, even if you wipe it with a tissue.
