Hi,

What product or home DIY solution will remove water spots from car
window?
Alchol, Vinegar do not remove those round spots.
Windex, BonAmi "Glass and Window Cleaner" do not. These are the spot
where the
lawn sprinkler water hits the window glass.

Thank you, Dave_s


What is the source of your sprinkler water? If it's the same as your
drinking water, then some of the methods suggested here may be the answer.
But if you're tied into a "non-potable" line, those spots are likely etched
into the glass.

In many areas today runoff and sewage treatment plant effluent are reclaimed
for irrigation use. I can tell you from firsthand experience that it will
etch glass and considerable polishing is needed to remove the spots.
Keeping the sprinklers from hitting the windows was the final solution.
