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

Wow.... I should have used this product sooner. I had some hard water spots that would not come off, along with sticker ghosting that could not be removed by using the below:1. Windex2. Some cleaner guaranteeing the removal of ghosting and difficult water spots3. Clay barNone of these worked at all. In comes Griots glass polish and instant (ok, not instant because there was some elbow grease used) shine!!!!!

Have hard water where you live , me too . Every time I wash the car I end up with these hard water spots and can hardly see through. Griots Glass Polish works wonders in removing them.. highly recommend

Used to polish some headlights and it did its job!

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.

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.

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

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.
