I have this god awful water spot on all my windows. Apparently, I didn't take care of him too well the first 6 or 7 months I had him and the sun must have baked the "hard" water at my house, into the glass. I've tried several methods to try and remove it. Even bought this high performance glass restorer and tried it last night and those freaking spots are still there. Looks hideous! Any ideas, other than replacing all 6 windows on how the heck to remove them? Has anyone used a buffing machine? HELP!

Try a claybar. You can pick one up at the local auto store.

Get it at Wal-Mart - awesome for glass, but do not get it on any painted surfaces!

Perhaps you can try the Turtle Wax Clay Bar liquid. It's supposed to remove impurities from Clearcoat, so it may work on the glass.

Water spots are usually minerals from hard water or mild acid deposits from acid rain. Minerals can be treated with a treatment like CLR or a Lime and Calcium remover, however if the drops have "etched" the glass due to acid in the water, the glass is most likely permanently damaged.

The best way to prevent water spots is to garage your car. If that's not an option, a cover. Third, use plenty of wax on the Clearcoat, and a treatment like Rain-X on the glass. You want the water to fall off the car in sheets, not bead into drops that leave behind deposits.

Good luck.

Thanks for the tips. The water at our house was very hard and acidic. We now have a softener but that doesn't help the damage that is already done. Really irritates me. And yes, it is being covered while at home. I heard about the claybar. Maybe I'll try that before I get a buffer and try that. Ugh!

CLAYBAR... I had spots on mine when I got it from the dealer. Claybar works AWESOME ON GLASS!

Steel wool, worked like a charm for me in the past with hard water spots baked on glass. I think I used glass cleaner to lubricate.

Good old newspaper and vinegar.

I have horribly hard water which caused some pretty bad spots all over my car. Clay bar did not work at all and neither did vinegar, the only solution was a buffer. I use Griots Garage stuff and they make a polish just for glass. Works great. You can use the polish by hand, but I would recommend buying the buffer since you will get a lot of use out of it for waxing and polishing the rest of your car. Good luck.

+1 on the buffer...You took the words out of my mouth..^^^^^^^^
