I just use normal hand sanitizer, and we have a few bottles of it around the pet store where I work, one right next to the cash register. It's easier than having to run to the bathroom every few minutes to wash my hands, and this way we can give customers lessons on good reptile care by leading by example.

Also when I do kids presentations with my animals, I make them use hand sanitizer before and after touching every animal. Gives the teacher and parents peace of mind, and I know that my reptiles will be just fine as well.
