Does anyone else have an OEM MB front windshield shade? I'm experiencing what can be best described as "fogging" of the front windshield on hot days except that the "fogging" doesn't go away unless cleaned off. I was told to try putting anti-fog spray on it to see if that fixes the issue and while it's "slightly" better it still does it. Does anyone have any suggestions of things to try? I'm wondering if maybe I just need to put some type of cleaner on the shade itself?

Help?
