So - about a month ago i got a brand spankin new windscreen and it was fitted by autoglass!
All seemed well for about a week then i started to get a LOT of fogging inside (i thought it was a coolant related issue but its not), so i used Rain X anti fog in the inside of the windscreen then, couple days later, noticed this "greasy film" on the inside of the windscreen - when trying to wash it off it just pushes it around on the windscreen.
You can't really notice it from looking at the windscreen, only when there is light shining through (eg: headlights) (in the pictures its a torch to simulate said light)
I've done some searching around and tried almost everything that's suggested, so I've tried the following:
- Rain X cleaning gel stuff
- Clay bar
- Screen Wash
- Glass Cleaner (for cars and not for cars)
- Vinegar & Water
- Vinegar (on its own)
- Rubbing Alcohol
