> Have you considered that these waterproof fabrics and their DWRs are not designed to have machine oil on them?
I have indeed considered that, and come to the conclusion that, in fact, no kind of clothing was designed with the express purpose of having machine oil on it But life happens, and bicycle chains of oil on them, and waterproof gear is used in more scenarios than just mountaineering. I am not going to leave a €550 Gore-Tex jacket hanging in the closet 90% of days because it is only intended for mountaineering, and life in the city could get it dirty.
I am also aware that stronger detergents would damage the fabric. I'm not accusing the makers of tech washes of deliberately selling bad products or being too incompetent to find the secret formula that gets all waterproof gear sparkling clean without damaging it.
I am simply saying that the limitations of these products make them relatively useless to me personally. If they fulfil all your requirements, that's great and I am happy that you are happy.
