Adam's PolishesWater Spot Remover - Hard Water Stain Remover for Glass, Shower Doors, Paint, Windows, Car Detailing | Calcium, Magnesium & Soap Scum Remover

As long as you follow the instructions, water spots are no match. Got rid of all water spots on my new car and paint is as good as new again.

I purchased a Lexus GX used from a dealer. Paint was great but windows were covered in baked and etched in water spots. Tried vinegar, window cleaner, compound, etc. nothing worked. While this takes some elbow grease and possible more than one application, it DOES work and works well. I was close to going to a professional but this saved me that headache.

This product works excellent on water spots a few days old, even from extremely hard sprinkler water (>500ppm), and after sitting in the sun. It worked on both glass and paint, but BE CAREFUL on glass, as it will etch the glass pretty badly. Don't spray directly on the glass, make sure the glass is cool and there is no direct sunlight, and clean the surface really well after. I sprayed directly on the glass and there was a little sunlight and I got etching on the windshield where the sprays were. I was able to get it off using some glass polish but it was a hassle. Overall excellent product, though, and does exactly what it is supposed to.

I used this product to try remove water stains on the side mirror of my car and it left a foggy “stain” on my side mirror. Please see attached photos.

This product works well to help get the spots off of those difficult spots on my auto. In their information, they show this works on home shower glass as well, so I tried it there. Now this glass is aged and in not great shape....it did not help much. So if you are getting it for that reason only, I am not sure I would have given a 5

I like that the product is more liquid than a creamy texture. But it did not work for my water spots on my windows. It’s easy to apply and I thought you would need to put a lot of elbow grease into it but it still didn’t remove my water spots. I didn’t realize you can apply this to paint so next I’m going to try my car and see if it works better

This product is amazing. I have a black car that has really stubborn water spots. It’s been driving me crazy trying to get them off. I put a little of this in with a micro fiber cloth, wiped dry and finished with a spray on wax. In less than 10 minutes, Wow!!! So easy, no elbow grease needed. I’m amazed.

The product works as it's supposed to as long as you follow the instructions. I had mineral spots on my car windows from water dripping in a parking lot. Sprayed the liquid onto a folded microfiber towel and worked it on the glass. Then washed with soapy water, rinsed and dried. The product must be removed after 30 second as it is an acid based chemical. If lefted on for too long, the chemical will etch into glass.
