Hi - we bought some Plexus to clean the windows on our dodger. The windows look like they are covered in salt stains and I don't think they had been cleaned for a long time before we bought the boat. The Plexus didn't get them clean. When I run my finger over the "stains" I can feel the texture change. Any suggestions on how to clean them, or are they just shot and need replacing?
