Zaino Z-12 Clear View Glass Polish

[mmouse]

Has anybody tried Zaino's Z-12 on a windshield with heads-up display. Zaino states : Due to recent manufacturer inconsistencies in glass production, it is necessary for you to test a small inconspicuous area prior to use to make sure it doesn't scratch the surface. I got some spots on my windshield from detailing the car recently and windex or any other regular stuff just doesn't do a good enough job of removing them completely so I thought to give a Z-12 a try.

White Vinegar or you can clay bar the windshield out of the sun. Lots of lube.

Thank you both. I tried vinegar and the clay bar and they both work great. I was not aware that you can claybar the glass.
