Hi, I googled this but all the results I saw were "How to waterproof your jacket" not you to clean your waterproof jacket.
I have an oakley battilion jacket to be specific. Its orange and I let my friend borrow it for a day. Some oil/grease icicles from the lift dropped on it and made it reallyyyy dirty in a lot of places.
Really appreciate some help/tips here.
Obviously I want to maintain the waterproofing.
