I have a problem with my MY19 Mk7.5. The windows look clean but when the sun hits them, particularly the rear screen it looks as if it's covered in fine very small fibres about 1 - 1.5 mm long - I don't think they are scratches and no idea whether they are inside or out. As well as the usual shampooing I've tried Autoglym fast glass and serveral other glass cleaners but nothing shifts it. Any ideas what it could be and how to get rid? The only thing I'm wondering is that the dealer put Diamondbrite protection inside and out - could they have somehow got that on the glass?
Thanks for your help
Ian
