Hi gang.

'96 RM WGN w/44K mi.
When I bought this car in S. Cal last February the car had been sitting in a driveway at least 18mo. Guess what? The sprinkling system for this well-to-do home with red brick driveway worked flawlessly turning on each day... and spraying the passenger side of the car.

I can remove the hard water deposits from the paint and chrome, and it does not really show much on the woodgrain. But the windows are another story.
What the heck can I use to remove the spots. I have thrown everything at it with no luck. Not even white vinegar, Heck, even the rubbing/polishing compounds I used on the other stuff don't cut through it. The acid-based custom wheel cleaner that worked on the alum trim was useless.

Now what?

At your local bimart, or such. Try some CLR. C alcium L ime R ust remover. It's what I've always used to remove the hard water deposits from shower heads and shower doors. That might work. Careful work with a razor blade might work too, I know from experience you cat take off tacky stickers that previous owners have applied that way.

Tried that too.

Can calcium & lime deposits literally ETCH window glass making the glass unfixable?
Is the water in Los Angeles lethal to auto glass if left on it over time?

If it's acidic enough, I suppose so, but I don't see how it'd be THAT acidic, and still be drinkable. IF it was etched, you should be able to feel it. There has to be a solution.

i know this stuff is expensive and not easy for the average consumer to get, but it works great for hard water stains!

I would think anything that could etch glass would destroy clearcoat and vinyl appliqué, wouldn't it?? Have you tried toothpaste? I've had good luck using that to get scratches off glass.

Anyone try using a clay bar?

O.k., I'll bite.
What exactly is a "clay bar"?
Something like cheap cat litter that is solid?
Where do I find one?

I'm still looking for suggestions on these annoying hard water stains. CLR does not make a dent.

Thanks

Here is a link you should be able to get it at a parts store or Wal Mart.
