When you find out what works, let me know. I've hard water stains on
my windows (particular the rear glass) that haven't budged after 6 yrs
of hand-washes and countless cleanings with windex/glass-plus etc.

On an unrelated note, my windshield is so pitted that the diffraction
of oncoming lights at night has made visibility dangerously poor.. I'm
contemplating having it replaced before winter really sets in..
especially with the sun setting at 4:30pm around here

Cheers,

Dave, not to ask a stupid question, but isn't there the chance of
really scratching up (fine scratches) the glass if you scrub/buff the
living daylights out of it...?

Not when the paper is a much softer material than the glass. In fact,
if the dry paper towel trick doesn't work on the water spots, an extra-fine
cut body polish would be the next step. It's only glass, it's not paint.

Dave - makes sense.. except I have streaks all over the front
windsheild, in nice arcs that follow the path of the wipers ... the
rubber shouldn't be streaking the glass, and any dirt on the glass
should be softer than the glass, so then what causes all those streaks?
It's definitely from running the wipers...I just think it's much easier
to scratch the glass than we would like.

On a related note - never scrub too hard on the inside of the rear
glass... I was feeling a little too motivated one detailing session and
ended up scrubbing out portions of the rear defroster (WTF?)... sure
enough, I run the defroster a week later and 4 lines aren't working
... that causes all sorts of static in radio reception!

not sure if it helps or not, but using normal car wax on my side and rear
windows has always removed any kind of hard water stains i've encountered.
