Why?
I have read studies that the antibacterial soaps kill only 90-95% of the bacteria present..the remaining breed and are already resistant to the antibacterial contents..so in effect you end up with superbugs that are fully resistant to the antibacterial soap.there are no "weak" bugs left to "breed" with..so ya get lots of John Wayne"s.
Regular soap and GOOD friction will kill most of what is on your hands..as will scrubbing countertops etc.
