Removing water spots from auto glass?

[mikeyb74]

Anybody out there have any suggestions that acutually work for removing water spots from auto glass? I've researched the topic on the internet and have tried some of these methods but nothing has worked. Things I've tried everything from regular household glass cleaner, white distilled vinegar and 0000 steel wool. After trying all of these things the spots are still there. Any help/suggestions with proven methods would be appreciated.

Clay worked for mine.

Elbow grease.

Not a direct solution, but to avoid the problem, I bought a California Water Blade and use it on all of my glass, including sunroof, right after washing and before drying the rest of the car.

I'm wrestling with this problem too. Little by little I'm getting it under control but its tough. First I clayed the windows. This did help but it was far from a complete solution. My next step was this .... http://www.amazon.com/gp/product/B0006IQJ42 ... Spot-X. It works pretty well on the really stubborn spots but its kinda messy to work with.
I'm playing with the notion that once clean the glass should somehow be sealed to prevent future problems. Its almost as if once you've had hard water spots (especially that have been there for a long time), then you're more likely to get them again.
I've never had them this bad before. My water hasn't really changed so I'm guessing that the PO (in Albuquerque) must've had some serious hard water.

I know what the spots are from. I have "Hard" water at my house.

I've had good luck using my porter cable with a cutting pad and whatever compound I have on hand, have used both Prima and Meguiars with good results. Of course have to use a small pad and elbow grease next to the edges and in the corners but this works better than anything else I've tried which has been most everything mentioned.

Go to a safelite auto glass and ask If you can have a bottle of there glass cleaner. I've used this to clean my whole jeep before.

Another solution is get that cleaner, spray it on, and take a razor blade and run it over it like you were taking a sticker off.

Toss a tech $5 and they will normally give you a can or two ofthe cleaner

Be sure to use Microfiber cloth.

I used my DA Porter Cable and wax on my Jetta's windshield and it removed the spots as well as acted like Rain-x
