washing clothes every day is crazy. you can't do it and stealth camp. you simply won't always have water that easily. wrap your head around washing clothing less often and easing back on the stealth camping to allow yourself to make use of public water sources. Even a lake is fine. I keep my sleeping back in a Trash Compactor bag for ultimate water proof protection (both are put into a stuff sack. Anywhere there is enough water I can put hot water into the trash compactor bag and make a sink. I can dig a small hole in the earth and use biodegradeable soap, and wash that way quite easily. It doesn't take much to wash your cycling shorts and they are about all you have to really keep clean-clean. Your largest cooking pot is probably big enough to do one pair of shorts per washing if need be, but a thick trash-compactor bag makes washing clothes really handy as long as you have running water to rinse them (or a lake that won't be damaged by a small amount of biodegradeable soap left in a pair of shorts).
