Like, hand sanitizer? It has its place. I usually have some in my purse for when I’m out and about and in contact with gross stuff. I do think it shouldn’t replace regular thorough handwashing, but sometimes, if you’re in a pinch, it’s just what you need. Plus, I handle cash a lot, and money is FILTHY.
(I am not a doctor, scientist, or anything with credibility or who makes a lot of money. This is just my own opinion.)
