Your a little confused as to what I was getting at. I'm not talking about cleaning the wound. I'm talking about cleaning the skin around the wound so the bandage will stay put. Granted there is some overlap, soap and water is generally used to clean both wound and the surrounding area.

As you point out alcohol is justifiably restricted to the area surrounding the wound. It hurts like hell and damages the tissue. The later potentially slowing healing and increasing the chances of infection.

Benzalkonium chloride solution is, IMHO, fine for the surrounding area but used directly on the wound it might be less benign. Recent evidence suggests that the compound may not be entirely benign. Being both a potentially toxic and allergen. Simple soap and water is far safer.

Unfortunately tap water, or sterile water, and a little soap, is fine but in short supply in the field. Which is where the alcohol swabs, baby wipes, towelettes, and mommy spit come in.
