Adam's Polishes Water Spot Remover - Hard Water Stain Remover For Glass, Shower doors, Paint, Windows, Car Detailing & More | Bio Safe Calcium, Magnesium & Soap Scum Remover Formula (16oz)

NOT WORK

Tried it on my 2017 Kia K3 that has stubborn water spots that cannot be remove by normal washing and polishing using Meguiar's Ultimate Polish. Followed instructions to apply a coating, wait 30s and wipe off. It removed spots from the door panels but only have small improvement on roof and hood. Not impressed, so don't be surprised if stubborn spots still remain despite applying multiple coats. Next I intend to try rubbing compound to see if any luck on my car roof and hood.Also tried cleaning a kettle. Worked great! LOLUPDATE: So I got the Meguiar's Ultimate Compound, went over 2 passes for the roof and hood, buff off and followed thru with Meguiar's Ultimate Polish plus Cleaner Wax paste. Finally able to get over 95% of the water spots out(See last photo). This time I am satisfied with the results!

Man I wanted this to work. I watched videos on YouTube and followed the label precisely. I reapplied the product multiple times after it failed without improvement. I even let it sit longer than advised hoping it would somehow penetrate and break up the spots but it did not. At the end I used a more aggressive technique while scrubbing but it didn't touch the water spots on my 2015 Lexus that already had a professionally applied ceramic coating three years ago. Maybe the spots are under the coding? Not sure but product didn't work regardlessUpdate. Just used it on my son's red 2016 Ford Mustang. Tons of water spots all over the hood and roof. Unfortunately this car sits outside of a garage and accumulates lots of sap. With very little effort applied this product then waited about 30 seconds and then use the neutralizing solution. Spots are now completely gone. Looks like a brand new paint job. I'm not exaggerating. Not sure what happened with Lexus but totally worked with this car.

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.

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 had hard water stains on the windows of my car and this stuff took it right off. Highly recommend this product.
