how to get rain spots off glass?

my truck has bad water spots on the glass all over and on the side mirrors. does anyone know if there is away to clean this off. i tried normal cleaners and scrubbing but had no luck. a buddy of mine said clay bar works good but he didnt know where to get any at. and ive never heard of it so i was just wondering if yall had any method off gettin them cleaned up good.

I USED TO OWN/OPERATE A DETAIL SHOP,I HAVE USED A CLAYBAR BEFORE AND THEY WORK BUT NOT ALL THE TIME. YOU CAN PURCHASE ONE FROM A DETAIL SUPPLY WAREHOUSE . ALSO I HAVE USED RUBBING COMPOUND WITH A STEEL WOOL PAD THAT HAD BETTER RESULTS . HAVE ALSO USED A BUFFING PAD WITH SOME WINDOW GLAZE AND IT WORKED , JUST DON'T GET THE THICK STEEL WOOL CAUSE YOU COULD SCRATCH IT UP. GET THE #00 KIND. THE PACKAGE SHOULD HAVE A NUMBER ON IT, I TAKE NO RESPONSIBILITY IF YOU FUCK YOUR WINDOWS UP LOL, JUST LETTING YOU KNOW WHAT I HAVE USED . GOOD LUCK BRO, IF YOU LIVED NEAR ME I WOULD GET IT OFF FOR YOU . PEACE

man ull have to forgive my knowledge of autobody and detailing. its not very good. but i need a #00 steel wool, and what is the window glaze? or rubbing compound im not familiar with it either. im sorry. could i pick this stuff up at the auto parts place?

Try some BonAMi powder and a wet sponge.
wet the sponge good,wet the glass,sprinkle the powder on ur sponge and scour the windshield or glass real good.Rinse the glass and try Rain-x on the side glasses only-not on the windshield as it will smear when u turn wipers on.Follow instructions on the Rain-x.BJ Disclaimer-worked on my waterspotted truck-might not work on yours-but BonAmi will not scratch unless u use it with steel wool.BJ

CERIUM OXIDE POWDER...it is designed for polishing glass and that is what the glass shops use....it is the only right way to do it.,

just for future reference, glass cleaner and newspaper work great when cleaning windows. i don't know what it is about the newspaper but it works great.

I worked at PPG for 5 years and we used.........toilet bowl cleaner, #0000 steel wool, razor blades and 3000-5000grit sandpaper.

yea i tried newspaper and glass cleaner, they work good if the windows aint staind. newspaper aint workin on these, where can i get cerium oxide powder? and how do u use it?

anyone?

try using diluted wheel acid. It always worked for me.
