Hi, Don't know if this is a Rover specific prob, but this seems like a good place to start...
Got an N Reg rover 416, and the inside of windscreen mists up (starting around this time of year) really badly. wiping with a variety of cloths that you would think would help just seems to smear it around - I've tried chamois (real and synthetic) freshly laundered cotten (no fab con) and kitchen roll - none seem to work. The only thing that does is a rubber squeegee, but that's not so easy to use when you are moving :-(
It's definately water mist as it does clear once the (fairly pathetic) blower gets up to temperature.
I wonder if the screen has previously been treated with something? I've tried various cleaners, but doesn't seem to make any difference.
Never had this kind of problem with any other car (and I've had several)
Does anyone know a magic cure?
Cheers, Bramblestick
