Have never had any problems getting ovies cleaned, just leave in basket with the rest of the Squadron's and it's all done under contract. The magic of RN Chinese laundrymen on board seemed to always get even OM15 out, but they always managed to shrink by 1/2 an inch as well.
When they got too tatty just went to stores and got new ones, no fuss, no bother. Old ones went into the stackers bin IIRC.
Suspect fightingchicken came across a rather green and uber-zealous stacker who didn't like plumbers!
Did get picked up once by a FOST fishhead who only wore ovies on exercises and hence they never got dirty. His had beautifully pressed creases down both arms and legs which looked V odd.
