Leave No Trace: Even biodegradable soaps and cleansers shouldn't be used in a natural water source. To wash yourself, your laundry or your dishes, carry water 200 feet away from streams or lakes and use small amounts of biodegradable soap (a little goes a long way). Then pour wastewater into a cat hole 6 to 8 inches deep.

Rated 5 out of 5 by from It works! I've used it only twice: one wash for gym clothes and the 2nd wash for a Gore-Tek drysuit. The gym cothes came out clean and smelling fresh -again. Next time at the gym the still smelled fresh. The drysuit required 2 rinses, but otherwise came out very clean and in great looking condition.
