How do I ??????

[Clay Pitkin]

Does anybody have any sure fire ways of removing hard water spots from glass on the side of a car? I have tried Windex, Bam hard water stain remover, and even a "high dollar" remove all that you can purchase at any gas station for about 4.00 per gallon, did not even touch it.

It looks as if the car sat next to the sprinkler system and it baked the water into the paint and glass.

Any ideas?

TIA

Try CLR, but test a spot first

My wife said we used a cleaner for showers with hard water spots. She can't remember the brand but it was the only thing that worked and it gets to 115 degs. here.

So does the paint also have spots?  A little rubbing compound would probably do it, depending on the type of paint.   

As far as the glass is concerned, I'd call an auto glass shop and find out what they use to buff out scratches from windshields.  Should be tough enough to knock down the calcium and fine enough to not distort or scratch the window.

Bonami might work on the glass, but I'd try it on a scrap piece before I used it on a car.

An electric or pneumatic buffer with medium cut compound works well. 000 steel wool or a razor blade works too but be careful not to scratch.

Clay, the product was Lime-away, works great on glass.

You might also try "Barkeeper's Friend", a product that is used to polish glasses and other kitchen items and does not have any grit in it -- rather it works by chemical action on the deposits.  Wear rubber gloves and do a test spot first.  I use it for the scale in the coffee pot, the rust and residue in the bathroom sink and toilet - as well as the stainless steel kitchen sink.  It comes in a golden container shaped just like a can for scouring powder.

Dilute Hydroflouric acid works well on Medical grade Pyrex Glass bit of a sledgehammer to crack a walnut if you know where I am coming from and wont do yer paint much good what about CILLIT BANG that we get over here BANG and the stain is gone

Thanks to all of you that replied. I went and bought some limeaway, that did some, and I even tried steel wool again some, alot less than before.
I will keep working with it

Thanks again

Clay,

       Like stainless said, i've had better luck with CLR then Limeaway. I've never had a problem with either one harming the paint. Good luck.

Straight Distilled White Vinigar. Breaks down mineral deposits, works better than any cleaner on glass.

Don't forget to drink Straight Distilled White Corn while you use that, then the spots won't matter as much....
