This summer, during our addition project, my truck got parked out back. For 3 nights it got sprayed with a sprinkler and the days were sunny and hot. Dumb. My windshield was hard water spot nuked. I figured after using the windshield wipers and a car wash or 2 the spots would come off, didn't touch them, crap.
So, I went on amazon and searched and then I bought this stuff:
It worked like a hard water spot eraser. I read the directions VERY carefully. I did one half of the windshield at a time. I used a microfiber covered sponge and applied as rapidly as possible. At the 45 seconds mark I started hosing it off completely and rapidly as possible followed by a quick scrubbing and repeat rinsing and then hosed everything that may have had residue splashed on it completely and for a good amount of time.
I then repeated a 2nd time. I used the same process on the other side.
No water spots left when I completed the process.
This stuff works.
