did you buy your car used, if so, they my have had some paint or an adhesive sticker in the windsheild that left some residue. Even after cleaning my windows numerous times, I can still see the outline of the window sticker in my rear driver side window, and there is still outlines where they used that wipe off paint shit. It's only really noticeable when the windows fog up or rain. If so, try a little goo gone, on a terry cloth, just a little bit, that helped my sitch quite a bit.
