So, for the record I've not had mine that long (4 months or so with as many wearings) but I don't really plan on washing it. I figure any dirt/stains etc. will just add to the weathering. If it starts to stink, maybe I'll rinse, but no detergent. Totally unmanageable spots (say PBJ, blood or some such, all over an arm or leg) may cause me to reconsider, but I'm afraid much of the dye and plenty of the weathering paint would wash out with a normal washing. Maybe dry cleaning if absolutely necessary, but I'm hoping not at this point.
