Vodka is sugary and sticky I think. You need shine! How about Everclear? Even Everclear is a little sticky for some reason. I guess any 80 proof-plus alcohol would be somewhat beneficial in a pinch, but if you really need antiseptic then go with rubbing alcohol. In my experience Isopropyl is cleaner to work with, and you can get up to 90% purity (180 "proof" and dries nicely), plus it is way cheaper.
I get that there is a dual purpose for ethanol--bartering and all--but it isn't very hard to keep some isopropyl in your pack too. I have a lot of those little flat pre-soaked wipes in my go bag for antiseptic. I figure if that is exactly what nurses use, then you can't get much better than that!
You and everyone else unfortunate enough to live in the only state in this great country, that doesn't allow take home alcohol sales on Sunday.
