Wilderness wash our super concentrated wilderness wash goes a long long way and is gentle on fabrics and skin but effective on dishes and laundry stains its biodegradable phosphate and fragrance free weve also made sure that the bottle it comes in is tough enough and the lid secure enough so you dont have to worry about leakage in your pack or bag although wilderness wash is biodegradable we recommend you always leave no trace outdoors so wash up at least 300 feet from waterways
