I don't have a picture but I was just told that the windshield is a laminate design. I am told that the laminate design is what causes the rubber to stick to the windshield at the point where the blade is at its max travel towards the drivers side and leaves a residue on the windshield.
I am told that using a wax that is free from any abrasives (good for clearcoat or fiberglass finishes) should help. I have not tried it yet, but I will.
I have used brand new ($60) dealer purchased and brand new generic wiper blades. Neither made any difference. The line, with rubber residue comes back. I have cleaned the blades and windshield with freon cleaner, alcohol, windex, etc. No difference. So far, the only thing that shows any promise is RainX, even though I was advised by an "expert" that Rainx would make the problem worse. When you get desperate, you don't always listen to the "experts" anymore.
I don't believe there are any other options available, but would welcome any additional pertinent suggestions.
I love humor as much as the next guy, but in all honesty, when I get an e-mail that there is a new comment on the Forum, and the comment is totally unrelated to my original question and can actually be interpreted as sarcastic, I really have no use for that kind of humor.
I have tried new factory blades at $60/pair and TRICO aftermarket blades. I have cleaned the blades with all manner of cleaners and cleaned my windshield with all types of cleaners. I have tried waxing the windshield and using RainX. Nothing seems to work.
Haven't tried Glass Scrub but I used a freon based spray solvent that got everything off the glass.
As for waxing, it did not cause the blades to skip. It still lft the same mark in the same place. I only tried waxing at the suggestion of a mechanic after this problem showed up so the waxing did not cause it. RainX has appeard to slow down the process a bit but not eliminate it.
I find it hard to believe that this problem has anything to do with the windshield or wiper blades being dirty. I have cleaned them so much that they squeak. Old blades, new blades, doesn't matter. The line comes back.
As I posted earlier, I had the same problem on my 2002 Grand Am. I figured when I got the G6, there would no longer be the same problem, but I was wrong.
I am thinking it might have to do with wiper arm pressure or perhaps the motor puts some downward force at the end of its stroke. I really don't see how it is environmental as I have cleaned everything as much as is realistically possible.
I could be the glass itself. I find the windshield on my Grand Am as well as the G6 very susceptible to sandblasting from debris on the road.
Anyway, I am open to suggestions, but any manner of cleaning has just not produced any real results.
RainX did not help much. Seemed to increase the time it took for the mark to become annoying, but it did make it very difficult to remove the mark. So much so that I bought No Touch Auto Glass stripper and used it to completely clean the windhield. The Rainx was not easy to remove.
Not much rain in the forecast here so i am not sure when I can report back on how well the No Touch works.
It finally rained a bit, but I was only out in it for about 20 minutes. I had cleaned my windshield (and wiped the blades with it also) with No Touch Windshield Cleaner and I do see that there appears to be little or no evidence of the mark.
It's going to be dry again for a while, so I doubt I'll have much more to add for a bit, but initially at least, it looks like the No touch cleaner is helping.
I have some new information. As I had said, I applied No Touch to my windshield. Yesterday was the first significant rain in a while and as I was driving home from work, after about 15-20 minutes, the mark started to reappear and get darker. I was using the wipers in the maximum intermittent position. I sped up the wipers to the max continuous speed, which was really too fast, but I noticed the mark started to disappear. I reduced the speed to the slower non-intermittent setting and by the time I got home (about another 15 minutes later), the mark was virtually gone.
I generally always use my wipers in intermittent mode and rarely use the 2 other settings. There is no dobut that the mark came back in the intermittent mode and disappeared in the continuous mode.
Usually, if I spray a window cleaner on my windshield, the mark becomes instantly obvious. This morning, I sprayed and it was barely noticeable. Usually, I have to use a lot of elbow grease to remove the mark but this morning, a light rub with the rag removed it.
I will keep you updated as I get more information.
