I dont know how to explain this without being able to take a good picture or show yall in person but ill try my best. On my front windshield, on the driver side, there seems to be some kind of strange defect in the glass. Starting from the edge near the A pillar and then streaking down with the windshield wiper to the hood is some kind of oily reside that will not come off. Its especially annoying b/c when I use my windshield wipers it creates this smudge of water infront of my face making it hard to see in the rain. I also noticed that when I wet my windshield during washing I can see the water coagulate in the area where the "oily" residue is. I have tried replacing my windshield wipers, used alcohol, used different types of glass cleaning products, and tried waxing/polishing/buffing it off. I even tried Goo-Gone. Nothing seems to work. I think there is some kind of invisible film on the windshield that might have come off in that specific area. Is this true?
