I read that when Chuck Yeager went camping on a river he would tie some of his clothes on a rope and let them hang in the current. When I'm in the Q and the wind is beating on the shore by my campsite, I weigh down clothes with rocks and go fishing. When I return, I squeeze out as much water as I can and hang them up. It doesn't remove much dirt but they smell better then laundered clothes from home.
Thanks for the twisted rope idea, I'm gonna use it!
