Pleased to see after all the other products I've tried this works! My windows are looking like new

I bought this thinking it was another gimmick but dang! My windows were so bad and this literally melts water spots! I’ve used buffing wheels on drills, top name brand stuff and none of them work as effortlessly as this. I did a frontier 4 dr in less than 2 hrs. I even ran over the bottle and it didn’t explode. I’ve sent this to my friends and family. I kept saying wow every time I finished a window lol. I can’t wait to do my Sierra and Camaro. Nothing like brand new looking glass!

I was amazed when I did the back windshield of my car because I wasn’t able to see at all, especially at night the difference it made and how amazing it took all the water spots off with a little bit of elbow grease! I recommend this product to anyone. A lot easier than my old way of rubbing compound and steel wool. Being a detailer myself this product is by far the best I’ve ever used!

I found this product amazing. Nothing I have tried even came close.

Removed water spots on my windows effortlessly

As soon as I received my Spotless Glass Killer, I grabbed a micro-fiber towel and tried it out on my sideview mirror. Because I had been parking beside a water sprinkler it had a lot of water spots. I dabbed a little of the Spotless Glass Killer on my towel and was extremely happy to find that it was almost effortless to remove those water spots. This stuff is great! I'm sold!

WOW Just Wow! With a little help from a costco hand held electric scrubber 20 years of hard water spots on our shower door are completly gone. And I mean "Completely"! Granted it did take about 3 hours and a full bottle but now i dont have to spend 1500 to have the glass replaced.

Keep in mind you will have to address the really bad spots numerous times before its completly polished out of the glass. Its not simple, it takes "work" from you to get the best results.

I have used solutions in the past for Hard Water Stains and Water Spot Build up on my Shower door. I have used Chemical guys solution. Does not work. I have used Vinegar, Lemon Juice, you name it. I got Spot Glass Killer in the mail today and tested it on a small spot on my beautiful show glass door. It works as it states. Put a small amount on Rubbed it in and the Hard Water Stain is gone, and spot build up has disappeared. I will be doing the whole Glass door this weekend. Very impressed with this product and how it made removing the stains pretty easy.

This stuff actually works as advertised! Highly recommend!

After trying many other products, Spotless X2 Upgraded Water Spot Remover for Glass removed tough water stains on our glass shower doors. I wish we would have bought it sooner, and we will be buying the before and after treatments shortly. I highly recommend this product.
