Two thumbs up. I tell people to mix 2/3 cup of 99% isopropyl alcohol (the cheap option) or 2/3 cup Everclear (the expensive option), along with 1/3 cup plain aloe vera gel. Add a few drops of your favorite essential oil or extract if you want it to smell good. Proper handwashing technique is still the first line of defense, but I certainly use the sanitizer at work between handwashings.
Question on the composition of sanitizer:
I've carried a bottle of hand sanitizer in my car for a couple of years or more. After a few months, the stuff loses its viscosity -- no longer dispenses like a gel, it comes out as a runny liquid. A lot like alcohol, in fact, and it smells like alcohol. Is it still viable hand sanitizer after it has lost it's gel-ness, or do I need to replace it?
