We just sailed the Edge from Hawaii to Vancouver, May 1 thru 11. We had a aft facing balcony Sunset #7310.It had 2 loungers and 2 chairs. We did ask the steward to clean the railing. It was very dirty. He explained that its soot from the smokestacks and never cleaned it. I guess in his mind, if you know why it's there then he doesn't have to clean it.
