Anyway, we've been parked up for a week in the sun and our rear windows are steamed up (between the double glazing).
They are not really sealed units as they have loose fitting plastic bungs in the top corners. I thought that they would clear after a few warm days, but they haven't.
Has anyone had this issue before (and found a cure?)
I'm concerned that they will eventually stain and never look clean.
