Don't ever use Clorox. It's highly alkaline and harmful for the tissues. Alkali burns are worse than acid burns.
I've used iodine, and I've used 3% hydrogen peroxide. They sting like heck on open wounds, and they're not particularly good for the healing process as they kill the tissue as well as the bacteria. I only use those if I know that I have some kind of infection in the wound. For a fresh wound, I let it bleed a bit to rinse out any bacteria, and clean it with a
chlorhexidine or cetylpyridinium chloride washing solution. If I have a choice, I prefer chlorhexidine. If it's good enough for pre-op sterilization, it's good enough for me.
Seconded.
I'm not sure what "skin eating bacteria" are, but if what the OP is worried about is
necrotizing fasciitis, I'd say the risk is really minimal, and that normal risks like being run over by a boat, T-boned in traffic or dropping dead from a heart attack are almost infinitely more probable.
