Review: It Works! - PROJE' water spot remover is a great product, and it works. It was very easy to use, both wiping on and wiping off. The spots on the driver side came off after applying spot remover once. The passenger side took applying the spot remover two or three times but eventually came off. More than likely the passenger side was the side that had the most sun. If it doesn't work for you the first time, keep trying.
Review: It Does EXACTLY What It Says It Does - I’m not one to write a review unless my experience was really bad or really great. For this product, it was REALLY great. It says it will move hard water stains. And it does. I had hard water stains on my ceramic coated hood and tinted windows since this past June and tried EVERY trick in the book to remove those stubborn water stains. I was about to purchase a water stain remover from Chemical Guys UNTIL I read that that specific product was not for ceramic coatings. And, of course, in typical desertcart fashion, they showed me similar products. I saw that this product was for ceramic coating AND glass, read the reviews, and purchased immediately. So I wiped the hood down first using a quick detailer for ceramic coated cars. Then using a microfiber sponge, I applied the gel to the sponge and gently wiped it on to a small section of the hood. When I tell you those water stains DISAPPEARED, they DISAPPERED! So I repeated the same process across the hood in small sections until all the stains were gone. I then repeated the same process to my tinted windows. Same result. 3 months of baked in water stains GONE. Mind you, I have a black car so getting these stains out was paramount. My car hasn’t looked this great since April when I had it detailed. Definitely with the money and the muscle to remove stubborn water stains!!

### ⭐⭐⭐⭐⭐ Works Wonders on Tough Water Spots!
*by T***1 on September 17, 2025*

I tried the PROJE’ Water Spot Remover on my car windows and paint, and I’m really impressed. The water spots had been there for weeks, and nothing else seemed to work, but this product cleared them up with very little effort. It left the surface smooth and streak-free, which made a huge difference in the overall look of the car. I also like that it didn’t have a strong chemical smell, and a little goes a long way. Definitely worth keeping on hand if you deal with hard water stains.
