Noel Report post Posted December 23, 2010 (edited) This is a repeat query from last year, about this time when the rains come and I find myself occasionally driving at night. I have a 2010 FFH, and this time last year I went on a quest to fix this annoyance which makes driving against traffic as in 2 lane highways downright dangerous! I bought and tried every conceivable glass cleaning product known to man, including clay, and finally went to the dealer, who said they would try acid next. I tried acid wash, it seemed to help slightly, and then it's right back to square one. I even contacted the dealer from where I bought the car to see if maybe they pre-treated it w/ RainX or equivalent to see if maybe that was the culprit which they denied. I bought two types of wiper blades touted superior. None of this helped. When the wiper move back and forth, a thin film remains that diffuses oncoming headlight glare and it is very distracting. I've never had a car windshield that did this. The glass looks perfect in daylight, and even in the rain during the day, it's only against headlights at night in the rain that the issue appears. So, is it defective glass? It's yours doing this? I talked to the dealer yesterday and they said they could replace it with OEM Ford windshield under the warranty. I'm just not interested in doing this if the same result will happen. Noel Thanks on the tip for my headlight aiming! It's fine now!

xmech2k Report post Posted December 23, 2010 I tried a couple of wiper blades and found the 'no-name' brand at O'Rielly worked the best for me, even better than the high-class ones. I admit, I didn't find my old favorite, Bosch Micro-edge. Just a thought, how are you washing your car? Car wash that gives a wax coat all over the car? A possible source of that mystery coating. Good luck! Quote Share this post Link to post Share on other sites

DaveM Report post Posted December 25, 2010 Since you have tried everything on the windshield my suggestion would be to replace the wipers as they are most likely the problem. Be sure to clean windshield again before using them as ours works great without a problem.. As far as the wax from car washes, I doubt it as if so there would be millions of people all over the country complaining about that. I have had many vehicles and all have gone through car washes weekly for more than 25 years without a problem. Quote Share this post Link to post Share on other sites

As mentioned in my post above, I did try two of the top-recommended brands of blades but to no avail whatsoever. I have to think at this point the glass must be defective, and the reason I am concluding this is because you have mentioned you are not experiencing this issue plus I have tried two new brands of blades and done maximum cleaning. I also did talk w/ the dealer the other day and they said they would cover replacement under a the warranty, however if new blades would resolve this I would choose this solution over replacing the windshield.
