Hi Karen, You wrote: "I've always found hand sanitizer superfluous, just washing ones hands with soap and water kills most germs." I agree that in the work environment you are probably correct but I think that hand sanitizers with at least 60% alcohol are good when you are out in public and can't readily wash your hands. I usually keep a small bottle in my car and an even smaller one in my pocket.

The ethanol in the active ingredient, maybe a mixture of 60% ethanol 35% water 5% isopropanol ( to make it undrinkable, but safe enough for topical use) would be better around circuit boards. It would tend to dry the users' hands, but would not help to contaminate circuit boards. I've always found hand sanitizer superfluous, just washing ones hands with soap and water kills most germs.
