My Countryman gets some serious film on the windshield by the vents closest to the doors. Is there anything that can be done to fix it or at least reduce it? Anyone else get this? I never had the issue with my Clubman S.

 

Yep, my mini has one too on the windshield. I didn't notice after a month of buying it. It looks like someone poured a certain liquid on it. I can only see it when it's wet. Weird .
