I can't imagine why I'd bother to do this. Is it a smell issue? That's all I can figure.

If you have a chance of getting road rash from bacteria, you've got some damn active bacteria there.

I try not to use ANY antibacterial stuff. For most people it does no good, and their use may be contributing to development of resistant strains of bacteria. Finding NON-antibacterial soaps and detergents is actually the problem.
