Remove hard water residue

[rick71]

Our condo has hard water in the sprinklers, and now I have hard water residue on my windshield. It is a stock clear tall windshield. Does anyone know of anything I can use to remove the residue?

Armorall, I use it on my windshield all the time, even though it says not to use it on a clear surface. Works great.

Filter your wash water.

I know this might sound insane, but some jeep softtop window cleaner works great on clear plasic.  I used it to clean my helmet too.  Its basically a light wax/polish.

And how do I filter the condo sprinklers?

Vinegar dissolves calcium.

But will the vinegar harm the windshield. I'll give it a try. Thanks.

I'd never have thought Amorall would remove hard water residue. I'll give that a try too.

Waxes cover it up. They do not remove it. Vinegar will work. If it is stubborn use Muriatic acid (brick wash). It is used by dealers to prep cars for auction. Takes SECONDS.

I used vinegar out of the bottle.  It removed a lot of the spots. Of course, not the scoot smells like a salad :-)

I'll have to find out if the sprinkler water is well or county utility. If it's  the same as the inside water, I may have to get some purified water to rinse next time.
