01

All glass is prone to stains and corrosion

On the outside, glass looks like a smooth, clear surface; however, when viewed under a microscope, glass has thousands of tiny peaks and valleys. This matters because, over time, minerals in hard water, dirt, and other types of environmental pollutants, can penetrate the surface and embed themselves into the glass. As a result, the glass becomes heavily stained and damaged.

02

How to remove hard water stains

With Glass Rescue™ at your fingertips, removing hard water stains has never been easier. Simply apply the product to a non-abrasive sponge and see how the product can remove most stains caused by limescale, soap scum, dirt, and minerals from hard water. And because Glass Rescue™ is super concentrated, a little product goes a long way when cleaning the surface.

03

Enjoy cleaner, longer-lasting glass

Don't let hard water stains on your glass shower doors bring you down any longer. With Glass Rescue™, you can easily and effectively clean glass water stains and restore your surfaces to their former glory. And for those who want to keep their glass looking clean, consider our water repellent coating, Clear-Fusion™ V. The coating chemically bonds to the glass making it easier to clean.

Best Product Ever!

I had been struggling with trying to get hard water stains off of my glass shower door for a while. My house is only two years old and to have to deal with hard water stains this early on is very difficult to handle and accept.
After making countless attempts to remove these stains using various methods I found on the internet, I was totally exhausted and nothing seemed to work. I then discovered an online blog where many people raved about Glass Rescue. I was very skeptical, but decided to give it a try. I could not believe my eyes! My shower glass now looks like it is brand new! And "sealing" it with a coat of Clear Fusion V sent it over the top! Customer service is top notch and second to none! Thank you DFI for producing a product that actually works! Bravo!

When it comes to removing all those stubborn water spots from our shower glass and windows, none of the online concoctions made a dent in our stains. Feeling out of options I decided to give Glass Rescue a try and boy I am impressed, our windows and showers are completely free of any water spots! I'll be ordering a Glass Defender kit to hopefully prevent future stains.

Great product

This is the first product I've tried on my frameless glass shower doors that actually worked.

Glass Rescue product

My boat windows have heavy mineral deposits that after a few applications and some elbow grease they are about 90% better.

Cleaned my glass nicely!

I don't know if anyone else has the same type of water we have, but it leaves a crystalized coat on our shower doors that is miserable to clean off. The Glass Rescue takes it all off, albeit with a bit of scrubbing. I LOVE it!!

The ONE product that worked!!

After trying just about EVERYTHING I resorted to the internet looking for something that would remove hard water stains from shower glass. I was ready to have a new shower installed!! Glass Rescue did the job!! Don't get me wrong, it wasn't an easy task as just applying the solution and wiping it off. I used Grade 400 sandpaper and Glass Rescue and A LOT of elbow grease!! The end result was worth the effort. An 18 year old shower now looks like a new one!! Well worth the $$.
