I picked up my M3 LR about 2 weeks ago. I thought the windshield was just dirty but it turns out it maybe some adhesive or other residual. Also now noticed some fine scratches on the windshield, too. The same residue is on the bottom of the driver side door. I tried water, Invisible Glass, rubbing alcohol, and vinegar without any success. Any clue on what to use. I do have Tesla Mobile Service coming next week for Homelink and added this problem to the service call. Thanks.
