Soap, by virtue of being soap, has antibacterial properties because it disrupts fat layers by making them dissolvable in water, iirc.

  This. Soap isn't an antibiotic as much as something that fatally disrupts the lipid membranes of bacteria, as well as messing with other oils you happen to have on you.

  Yes, I know that, which is why I specifically mentioned soaps lacking triclosan.
