A bit off topic here, but everyone that's carrying around betadine realizes that it needs to DRY before it's actually sterilized anything, right?
Uh oh. I have been scrubbing my hands with betadine before surgery for years and never let it dry. I rinse my hands with water (tap water at that!), dry them, and then don gloves and gown.

Letting it dry is good because it leaves a bacteria resistant area, for lack of a better description, for hours, but iodine, wet or dry, will kill bugs.
