I've been having problems with vertical marks on the insides of the windows on my '07 TL-S every time I roll the windows down. They basically look like greasy smudges, about 1/8" wide, and straight up and down. Has anyone else seen this? They're not scratches, because they do come off, but they're not easy. I have to take a fingernail to some of them to get them off. I do have my windows tinted, but I had my last car done with the same tint, by the same guys, and never had a problem like this.

 

yes, I do not have tinted windows and I've noticed this as well.

 

so how do we get rid of it...i have the same problem and dont want to scratch up the tint trying to clean it off...

 

it may be some glue stuck to the felt or wiper that rubs against the window, I would remove the wipers/felt and clean glue off.

 

I know exactly what you are talking about. I get "stripes" on the inside of my windows as well and I don't have tint. I just clean it with stoners invisible glass and it comes right off but as soon as I operate the window a few times the stripes are back!

What (s)he said. I ended up going back to where I got my tint done (Solarworks in Roswell, GA--they've been mentioned here before, and I highly recommend them), and that was what they told me. Actually, they said that the glue behind the felt had started to release, and was getting smeared on the windows. They cleaned it for free, and told me to come back in if it ever happens again. He also said I was the third TL to come in over the last three months with this problem, when they would never see it before. I had noticed that the felt was much more exposed under the weather stripping than my previous car, so I wonder if that had something to do with it.
