polishing glass?

[terminator808]

My moms brand new SUV has some hard water spots on the front windshield.  Also I didn't have adams window sealant and used the rain-x windshield treatment that acts like a sealant, but when the sun hits it right or when it gets wet it looks like i never wiped the product off the windshield.  I tried just using some window cleaner, water spot remover and clay baring it but nothing worked, even a little bit.  Does anyone have any advice or tricks on how to get rid of this??
 

thanks in advance

Make sure the inside is clean. I had a similar situation on my Camaro a long time ago. I thought the glass was stained but turns out I had a nasty smear on the inside, lol! Try scrubbing the outside with Barkeepers Friend and a sponge.

Clay bar?

Try 0000 steel wool with Glass Cleaner as lubricant.  Be careful around edges not to scratch paint and/or trim.

I don't think is breaking a rule since Adam's does not sell such a product so....

 

Try Ceriglass with a Rayon pad on a DA Polisher... I have had pretty good results with it, not always amazing but it usually got out water spots.

I've read that 0000 Steel Wool can scratch glass, so I would be very careful with that method (not tried it myself). I'm curious to try the Barkeepers Friend mentioned above, my recent acquisition could use some deep cleaning on the windshield.

It works great! I scrape it with a razor first then clay. Then use a damp sponge to make a paste of the powder and scrub. Follow up with Adam's Glass Sealant or whatever you have.

I have had excellent luck using a 4" foam pad, paint correcting polishing, and a cordless drill. Trying by hand will not work, need more power.

yeah what he said^ Paint correcting polish and 4 inch orange foam pad with a cordless drill. Did it on all the glass on my truck and it came out awesome.

I have never had #0000 Steel Wool scratch any exterior glass yet, but you have to make sure it is the Ultra Fine 0000 version. You do not want to use it on tinted or frosted glass, rubber trim, or paint though.

 

I always suggest trying something like Brilliant Glaze to clean the glass first though if claying doesn't remove everything. I've also used our Correcting Polish and Finishing Polish with a machine on glass before, but you need to be careful with respect to machine pressure and vibrations on the glass.

I had some stuff n my glass and tried all kinds of stuff, in the end a bunch of detail spray (prob more than I needed actually) and #0000 steel wool (which was dirt cheap ad home depot) and I have not had any problems yet.

For water spots the above will work. For wiper scratches you need cerium oxide.

Thanks for the quick replies everyone!

Ill give the steel wool a shot and see how that works
