1. Shower before leaving.
2. Upon arrival, take as much off as possible without scaring your co-workers.
3. Spend about 15 minutes cooling down and toweling off with a damp cloth. Rinse and repeat a few times until you've dried out.
4. Apply deodorant.
5. Change into clean, dry clothes.

I *hate* feeling any amount of sweat on me at the start of the day, so adjusting took awhile. Yeah, I still feel like I'm only about 75% clean, but I can live with it until I get home at the end of the day.
