The window trim on my Model Y has been stained for a while now. I never noticed this when I picked it up in January of this year, so this must've happened sometime during the time I've owned it. I've taken it through an automatic carwash a few times (touchless of course) whenever I've felt lazy or the weather wasn't right to wash it myself. I also had the entire car covered with PPF. These are the only two instances where I would think it could get stained - chemicals in the carwash soap or whatever solution they used to apply the PPF. I've tried scrubbing with rubbing alcohol, but there is no change! Has anyone else had this problem? Any suggestions?
