Hard water spots on windshield

[Laid GP]

Spent about 4 hours polishing my car yesterday in which I somehow neglected to dry the windshield

, which now has lovely etched water spots all over it. We have super hard water here. What's the best way to get rid of them?

Hi Chad, try a clay bar treatment first, with either Detail Spray or Glass Cleaner as a lubricant for the clay. If that doesn't work you could try Brilliant Glaze to remove them. Next I would move onto Revive Hand Polish and then machine polishing, being careful not to put too much pressure onto the windshield. Lastly, I would go to #0000 Ultra Fine Steel Wool, with Adam's Glass Cleaner as a lubricant for the steel wool. Use only ultra fine #0000 Steel Wool, as other types can and will scratch the glass.

Had great luck with the #0000 steel wool and detail spray in doing my glass, just make sure to use plenty of DS for the lubrication.

Iv seen people take the 4 inch backing plate with an orange pad and a cordless drill, and some correcting polish to get the water spots off the glass. Personally I have never done it myself but will be soon because i noticed my back windshield is covered in water spots. But like Dan said, defiantly got to be careful with the pressure and the Pad temperature. Let us know what works!

You took the words out of my mouth...... the 4" Focus pads will do the trick, clay first then Orange pad & CP.
