Currently, I have the most fortunate advantage of having a full shower at work. I love it more than any other non-monetary benefit.
Formerly, I did not have that luxury. I would use (and still do if in a pinch, or going somewhere else that I need to be "presentable") anti- monkey butt towels. I buy them on Amazon. I've heard very good things about Walgreen's skin wipes, but we do not have a local Walgreens. Other skin wipes I buy from the grocery all seem to have a very perfume-y, lingering odor. I bought some from L'Occittane, but cannot afford to use those frequently. I carry a couple in the seat pouch of my road bike, and in full quantity in my commuting panniers. If I ever leave my job, I will definitely only leave if they have washing facilities. There is nothing that can compare to the comfort of sitting all day behind this damned screen squeaky clean.
