I keep a spare clean pair of shorts and jersey at work. I then wash the dirty cloths by hand in the restroom sink. I then squeeze out as much water as I can and then wrap them in one of those fast drying synthetic towels you can get for camping and then hang them to dry in my office. They become my clean pair the next day. This strategy depends on having a place to hang them. Wrapping in the towel assures they will dry without dripping and be dry the next day just by hanging there.
