Griot's GarageFine Glass Polish, Car Window, Windshield Polishing Cleaner for Automotive and Home, Removes Stains and Water Spots, 11017, 16 oz

Used to polish some headlights and it did its job!

returned was a resale item and almost empty. cannot blame griot for that!

I am not a Griot’s fan for life. After several failed attempts to get hard water spots and etching off my glass this is what finally did the trick.

Okay, so I bought this Griot's Garage Fine Glass Polish because my windshield looked like it had been permanently decorated with 14 years of water spots. Honestly, it was like looking through a Jackson Pollock painting, but instead of artistic splatters, it was just mineral deposits.I hooked up my orbital buffer and went to town. Let me tell you, this stuff works! The water spots are GONE. I mean, G-O-N-E. My arms, however, feel like they've been doing bicep curls with a small car.Here's the thing: while it obliterated the water spots like a tiny, aggressive army, it didn't quite vanquish the tiny scratches on my front windshield. I was hoping for a "brand new, straight from the factory" level of clarity, but it's more like a "significantly improved, but still slightly weathered" situation.So, four stars because:Pros: Water spots? Dead. My windshield is now significantly less abstract. My arms are now impressively toned.Cons: Didn't quite erase all the tiny scratches. Maybe I need a diamond-infused buffer? Or a team of trained squirrels with tiny polishing cloths?Bottom line: If you've got water spots, this stuff is your savior. If you're looking for miracle scratch removal, maybe temper your expectations. Still, for the price, it's pretty darn good.

There’s a reason this product is highly recommended! They polish glass magnificently especially if your using an orbital polisher.They just do not take out scratches. Look else are if that’s a need

This stuff is the amazing it cleans it polished out big scratches and doesn't take much to get the job done.

About a year ago I decided to paint correct and apply Adams Advanced Graphene Coating (great stuff!) to my 18 month old Chevy Colorado. I was never happy with how my windshield appeared straight from the dealer. It always seemed to have a haze, or oily residue and I swear when it was foggy you could see the suction cup marks on either side where it was held by robot during installation!!Ordered this stuff and Griot's Garage 10614 6" Glass Polishing Pad (Set of 3) for use with my Ryobi cordless orbiting polisher. Now it is a LOT of prep if you're going to do all windows because you MUST tape off everything that is not glass. Glass is HARD so whatever will polish it WILL scratch the hell out of trim, paint and plastic. I tested on rear window behind driver in case it clouded the glass but it worked GREAT. I'm telling you I've never seen such clear glass. Took whatever film was on windows right off!!I used to hate cleaning glass because it always streaked - not anymore!! Spray on, wipe off, crystal clear. Applied Ceramic coating on glass after carefully removing all remaining polish and over a year later the water STILL beads up and runs off like it has permanent Rain-X on it. Love it - Love it - Love it

I am sure that this glass polish works great but I returned it after reading the instructions as it appears that it will be very time consuming to apply. You need to tape off all surrounding rubber trims on your windshield prior to applying this.
