Hope there aren't too many squeamish guys reading along...
I've always been told not to use soap or any kind of cleanser "down there" because it will put the natural acid balance out of whack and cause infections. The inner parts (vagina) are self cleansing, but the outer parts (labia) should be cleaned (but not harshly or too often) like the rest of the skin--I just use water (and my hands, no washcloth--too delicate) too. I've never had any issues/infections whatsoever, and feel perfectly clean
