A nightmare! I posted in another thread and got all sorts of "advice" and some poor-mouthing too ha ha. My $100,000 car was delivered with a fine layer of schmutz on the windows, and the microfiber towels left tiny things that made a million little gleaming flecks under certain lighting conditions. Also the glass has a milky color in sunlight that I have never seen on any other car, ever.
The advice I got that worked best was to use "glass polish' which is like old school Glass Wax, a diatomaceous earth based cleaner. I used
Griot's Fine Glass Polish and a
$30 Auto Zone random action buffer. What a mess! That stuff creates loads of powder fine chalk dust that gets all over the molding and in every crack. Awful! WTF? Why did I have to do this to get the s**t off my glass?
Well the results were pretty good. No more "zillion stars" and streaks, but the milky color is unchanged. I think it's in the glass maybe the laminated stuff in the center.. I use Invisible Glass for window cleaning, and I can still see the ghosts of a giant sucker and smaller square patches on the glass. Invisible Glass gets bugs and stuff off, but it will NOT remove slime/glue/shipping-wrap residue, none of that stuff. Maybe more Glass Polishings will be required?? I hate doing it since it is incredibly messy.
I'll try Spraway as discussed here.
