Chemical GuysSPI1081602 Heavy Duty Water Spot Remover, Safe for Cars, Trucks, Motorcycles, RVs, Home, Office & More, (2 Pack) 16 fl oz

I was honestly skeptical at first, but Chemical Guys Water Spot Remover completely blew me away. I had stubborn water spots etched into my paint and windows that just wouldn’t come off, no matter how many washes or clay bars I used. One application of this product, and the difference was immediate.It’s super easy to use—just apply with a microfiber towel, let it sit briefly, then wipe off. The spots were lifted without damaging the clear coat or leaving behind streaks. I used it on my paint, glass, and chrome with excellent results all around.If you're dealing with hard water spots or mineral buildup, this product is a must-have. It saved me from having to polish or even repaint. Definitely a 5-star product from Chemical Guys!

I had a professional detailer that could not get the hard water stains from our sprinklers off of my Mercedes.He did the full wash, wax, clay bar, everything and could not remove the spots.After reading the reviews on this product I decided to take the chance and purchase two bottles.I received the bottles within a couple days along with their finishing wax and applicators and tested on a small spot and did not see any issues on the pain so I decided to do the whole side that had the water spots.Following the instructions exactly I was amazed to find that it eliminated the water spots almost immediately, some areas took additional work but after another pass it cleared out all of the hard water spots.I only used maybe an eighth of one bottle and it took care of the whole side of my car so I let my detail or know about the product so he could use it for reference in the future.I didn't tape off a before and after section but I did take some pictures below that will show you the treated spot and the untreated spot and the final product so you can see the difference.It was as easy as waxing and buffing.Great product highly recommended.

Great stuff! I've had really bad water spots on my windshield for years. I asked detailers, body shops, and glass installers what I could use. I tried all the suggestions. Rubbing compound, vinegar, clay bar, and Bon Ami among a few. While researching glass replacement, I saw on forums that people had good luck with this stuff. Although skeptical, I ordered a couple bottles. It didn't do much applying by hand but when I used my 3 inch buffer, the spots became virtually indistinguishable on the windshield. Now I had a severe case of water spots on my 19 year old truck so I don't expect perfection but I got the next thing to it. I did however remove the spots on the paint with hand application.

Works on not so old water spots but the much older ones it did not work at all, unless it needs a lot of elbow grease.

This is one of those products that works so well it makes feel obligated to run and write a review. I'm not gonna get into any details and I'll just say it does what it's supposed to do, remove water marks. After just a few light passes with a microfiber applicator that drops disappear. Well worth the money!

Why did you pick this product vs others?:After trying it with baking soda and other tricks, I decided to give in and try this for hard water spots on our car, mostly from a sprinkler nearby where we park. It took a bit of elbow grease to rub the gel with a microfiber towel but it worked like gang busters. Some spots I can still see the remnants of the hard water spots when trying to see from an angle, but it definitely got rid of most of visible ones. I waited until the car was covered in the shadows, washed the car with soap and water, dried the spots and then applied the gel. They warn you to not do this under direct sunlight. As soon as I got most of one side of the car finished, I immediately washed it off with water and sponge rubs.

Sure, this might get some of those easy water spots off your car’s finish, but it is ineffective on deep spots.This might save on use of some elbow grease, but it’s not a very good product.

Great product! Does exactly what it claims, to remove water spots. Please use as directed. Use in shade and early morning is best. Clean surfaces before use. I had a water bucket handy and several nice micro fiber cloths. I used a small area and gently used in circles. They easily removed the spots without using any hard rubbing at all. I used one cloth to removed product film, the used a light soapy water with another, then used water to removed any soap, and finally used another cloth to buff it all. Sounds like a lot of work but really wasn’t. I was able to go to another area next to the one I did and repeat. Then another til the entire hood was done. My hood looks like new without any water spots. I now carry a squeegee to remove any water drops on car but have great faith in this product. Do it right and you will be well pleased. I am.
