If you have a restroom at work, it can be done. I use a washcloth at the sink in one of the public restrooms at my campus, rinsing all the exposed skin and wiping down my shoulder-length hair. I keep a bag of toiletries in my file drawer (I have no office of my own but share with dozens of other adjunct faculty.) After I've rinsed off, I take a stall and undress and clean the rest of me with the washcloth, then go over again with Wet Ones (I like the citrus-scented kind.) I have a hand towel for drying off but rarely use it because I dry quickly in the air conditioning and it feels good after my mid-morning commute, when temps are already nearing 90. I get dressed (I bring my clothes every day in panniers,) and then I go out to the sink again to put on make-up and comb out my hair, which I allow to air dry. I use a body spray, too.

I smell great and feel as refreshed as if I had just had another shower.
