There's no evidence OTC antibacterial soaps prevent disease more than washing with plain soap and water. Some antibacterial drugs can do more harm than good.
Anyone know if scrubbing with water alone is better or worse than not doing anything? I've occasionally ended up in public bathrooms with no soap and I wonder if I should use water or not.
Yes, scrubbing with water is still useful. Besides being a detergent, what soap does is raise skin pH to make it less likely that bacteria can grow on the surface.
