Using Magic Eraser on windshield

I've had to resort to body shop 3m heavy duty compound@ 3000 rpm's to remove etching on glass before. It was a 98 camaro, I have to go over it three times, then op via rotary and white pad. If dg and a orange pad worked, it most likely wasn't etched too deep.
 
Here is the water spots im fighting. Clay, steel wool, vinegar, all did nothing.



I worked some M83 in by hand with a terry towel and it knocked some of them down. Ive yet to try it with the PC and a cutting pad..

I'd try Zaino's abrasive window cleaner. If that doesn't work, I'd try Lime Away, but be *extremely* careful that it touches *nothing* other than your glass. You could also go to a janitorial supply outlet and ask them for a phosphoric acid based cleaner. If they don't have any phosphoric acid based cleaner, they may try to steer you to a hydrochloric acid based window cleaner made specifically to get rid of water spots. You could try it, but be extremely careful. It's really, really nasty stuff.



If you try all those things and the marks are still there, you can be darn good and sure that they are not mineral deposits (water spots).

I second JesseLyon2002's suggestion. Duragloss Nu-Glass has been the only thing I've found that works for bad waterspots on glass. My car had bad waterspots when I bought it, and I fought them for awhile. Tried scouring pads, every window cleaner, vinegar, and some paint polishes. A local glass shop recommended the Duragloss, and tried a test spot for me. Took them off immediately, so I bought the bottle. It can be used by hand, but a PC makes it almost effortless. It can be found at a lot of glass specialty shops, or online. A little bit goes a long way, so a small bottle will last awhile.

Thanks for the info on Nu-Glass Dave....took care of my wifes SUV tonight. Now she can actually see where she is going when it's raining. Picked it up for less than $8 at a local CarQuest.
 
Well, I have yet to have a chance to work on it so I told Mazda about it just a few ago during my 5k mile service. They didn't understand what I was talking about at first, partially due to it being difficult to explain, then they "fixed it."



It went something like this:

"We cleaned up your windshield and a lot of it should be better."

"Out of curiosity, what'd you use to get it off?"

"An industrial cleaner we have here."



I go out and test it out (spray the windshield and use the wipers). Yeah... it's still there. Not to mention the dirty areas that the windshield wipers don't get were still there just like they were when I dropped it off. They could of at least cleaned the windshield and pretended to have done it instead of lying. :bat



Anyways... off to buy Nu-Glass... I'll letcha all know how it works.
 
My dad's truck had really bad spotting on the passenger side windows. I searched on the forums here and then tried the magic eraser, vinegar and even steel wool to no avail.



I finally bought some 1Z Glas Polish and it worked like a charm. Highly recommended!
 
I still haven't found anything good locally. :( I'm about to break down and order something off the internet. Any suggestions for something else local?
 
As an update to my post, I finally used a Megs cutting pad with #83 and it took everything off. Ive tried all the other methods that have been posted and nothing worked. Ive never seen my glass so clear. Put down a good coat of Rain-x and I had some nice looking windows.



Ill probably do it again this spring and make sure to pay more attention to the edges and corners. When it rains you can tell where I did and where I didnt polish.

Have you tried Rain-X Glass Polish? It's available at Murrays or Autozone.

I'll try that if I can find it at Autozone (about 1 mile away). If not I'll try to track down a NAPA in the area.
