I always have a shower when I get to work, so the socks, pants, overpants, thermal top, tshirt and whatever else gets rinsed thoroughly in the shower, then squeezed out and hung to dry in the compressor room, which no-one works in and has strong ventilation. The jacket gets hung out by my workbench, doesn't stink too much. The helmet, gloves and shoes I spray with a alcahol/water mix to kill any bugs living in the sweat, and left to dry near my workbench (I'm bluecollar). I also spray the alcahol mix in my work boots after a 12 hour shift. No probs with athletes foot now - no expensive cures needed.
In this particular department I think I may have the best job ever. The showers here are mind bogglingly good. I get out when I start to weaken from the heat.
At home I wash the cycling pants in the shower, but everything else goes in the wash, except the jacket, which I use every day and wash on my days off. Unfortunately this has resulted in the bright reflective material of the jacket suffering some mold, when its spends periods of time damp with sweat and no drying air current, which is really only an aesthetic problem. One I would like to cure somehow though.
