I have never taken my E90 to a carwash and have only washed by hand with microfiber. But when I took the car in to the dealer for a software update several months ago, I forgot to tell them not to wash it. I have subsequently noticed several scratches on the windshield, particularly on the driver's side, with a circular pattern. They are not particularly noticeable during bright sunlight or at night, but at dusk when the sun is low, they are clearly visible. I have tried the Sonus glass polish and cleaner, which helps a bit temporarily. Is there anything else I can do?

Are you sure they aren't wipe marks on the inside of the glass (from using a damp rag)? I hate that. Invisible Glass or another glass cleaner should take care of it, though.

thanks, but I have cleaned the inside and outside of the glass thoroughly (several times!). They are definitely scratches on the outside of the glass.
