Yeah… it's something I've been thinking to wash things with plastics, but you have to think that dishwashers aren't washing machines and they don't have "just tap water option". If you want to remove soiling from dishes in the end you need hot water. More hot or less hot, but hot water. I think lime gets brown with hot water from the tap…

For us is really a headache because it's the first time in our lives that we have to face this issue…
