I work at a BMW dealer and we have a broadway drive thru carwash that all of our customers cars go thru. Gets cleaned once every two weeks with filter changes. It uses a car wash soap that they refill and no other chemicals. All of our customer cars come out looking just fine. I've used it a few times and my cars paint is no worse for wear.
