I have cleaned the interior front and rear glass at least twice a week since I bought the car. Not because I want to but because within a day or two of cleaning it, a film or fog appears on the glass. It is like a smoker's haze on the glass, but no one has ever smoked in the car. I am concerned that it is some kind of vapors coming from the dash or seat material and that I am breathing it also... The man who details my car also has an Avalon and he says he has the same problem also, and cannot solve it no matter how hard he tries. Any suggestions?
