So I did the full deal on the car this weekend: Zaino inside and out. Looks better than it has in a long while. But, I can't seem to get my windows clean. I used Z12 inside and out on the windshield followed by Stoner's. It still didn't look good. There was still haze on both sides of the glass after repeated Stoner treatments.:confused: I was thinking about getting some Eagle 20/20 just to see if that made any difference.
I'm sort of assuming that your car is a '99. It sounds like what you are dealing with is the "out-gassing" of the vinyl on the dash, etc. This is extremely common, and something that most everyone deals with.
If Stoner's invisible glass did not remove this haze, then I would also try ammonia, being careful not to expose the EPDM rubber to it. The ammonia should cut through the haze, but don't be surprised if it reappears.
