Markings on the windscreen
I need some advice in getting rid of some markings on my windscreen.
I bought my car used, and there are some markings (looks like paint) on the windscreen that only becomes visible when the windscreen fogs up, or when it's really wet outside. The windscreen looks perfrecly normal when it's nice and sunny. I've tried cleaning it with different cleaning solutions but have been unable to get rid of it.
Any ideas on how I can remove that permanently?
