Live long, and be smelly!

Nothing. That's my answer. I would do nothing with them other than (maybe) find a spot to hang them where
they can dry out during the day. I can only assume that the bacteria build-up shouldn't be too bad, given that
it's from you and you are traveling between home and work. In other words, I'd only consider cleaning/rinsing
every day if I were on the open road and not bathing regularly. Then again, I wear regular cotton shorts and
gave up the chamois life awhile back.
