The inside of my front windscreen has grease type marks on it. It has been like this ever since O'Briens fitted it after replacing my front windscreen.
I have now tried normal windex, orange oil cleaner and just wiping it (lots) with a paper towl and nothing seems to have shifted the greasy marks too much which really haze up in direct sun.
Anyone have any tips of what I can do to clean it ?
Thanks
