Hi everyone. Took delivery of my S85 almost two weeks ago. Just last week as I was driving home from late night hockey, it was the first time I was driving in humid conditions and the windshield was fogging up. Weird, front defrost wasn't working. Then I realized the outside was fogging up. In fact, it was fogging up so fast that i re-fogged after a single swipe of my wiper so I had to keep them on like I was in a rainstorm. To wipe FOG. Looking outside to every other car on the road, no one else was having this problem. Looking closer, I could see that there is actually a thin residue on the windshield - if i took a damp cloth and wiped across the windshield, I could see remnants of the residue by looking at the windshield at an angle. Cannot see this when it is completely dry. I realized this is what was causing the fogging (residue picks up the moisture, but shouldn't happen on clean glass). Windex didn't help. I ended up using a solution of baking soda as a mild abrasive and scrubbed my windshield down - problem solved, totally smooth, residue gone. Haven't driven in humid conditions again, but I suspect the fogging problem will be gone. I think this residue is from the plastic on the windshield after they rip it off on delivery. The guys at the showroom probably didn't see it because once you wipe it with windex and it's dry, you cannot tell. Did anyone else here have this experience, or any useful comments?
