this was a custom I made for someone into wet and messy jackets, but in this case, CLEAN and wet jackets!! I got in the shower and started with my thick, blue waterproof snowboarding coat, soaping it up and getting it wet as much as possible, before taking it off and repeating it three other times with a maroon mountain hardware jacket, a Patagonia jacket with orange and green, and a water resistant dark blue north face jacket!! Each of them nicely shampooed then rinsed and as wet as possible!!!! I used Dr. Bronner’s Soap! It’s a great soap for everything and a little goes a LONG way and I about used almost the whole bottle! Enjoy
