Diamon-Fusion International

It's the ONLY thing that has worked on our shower doors!!! I absolutely would recommend them to anyone who is struggling with hard water stained shower doors!!!

Ok, so I read through the entire forum dedicated to removing stubborn hard water stains from a shower door. In this post, people recommended a number of things and I tried nearly all (toothpaste, mixing CLR with BarKeepers Friend, Hydrogen Per with Vinegar, and DFI). I tried the DFI product and literally watched about 3 years of water stains disappear before my eyes. I used the powered one btw (Glass Rescue). Everything else worked fairly well but none of the others fully removed the stains with such ease.

Hard water stains have been an utter plague for me in East Texas. The municipal water leaves residue and staining on nearly anything and everything it touches. From the glass and counter surfaces in the bathroom, to the kitchen, to the car, to home windows etc. Until recently, this has become a war in which I have spent loads of money and suffered great frustration and disappointment. The discovery of DFI hard water stain remover has been nothing less than MIRACULOUS ! This sounds like a crappy infomercial, but it’s absolutely unbelievable. It comes in a powder form and a super concentrate liquid. Both remove the hardened scale with almost no effort. This stuff ranks higher with me than WD-40 on the list of astonishing substances. Don’t mention this stuff to people you don’t like. I have not tried it, but DFI also produces a hydrophobic glass protectant that is said to resist staining to begin with. I’m definitely going to buy it. I haven’t been compensated by anyone to make these comments. Darran

Wow! I saw DFI Glass Restore mentioned in a blog post here regarding impossible to remove hard water stains on glass shower doors. I've tried for years, to no avail. I contacted the company, and asked if they could send me a sample. They have great customer service, and sent me a free sample right away. I used the product (NO HARD SCRUBBING NEEDED) and got fantastic results! Where has this product been all my life?! Glad I know about it now! My glass shower doors look 100% better w/ only 5 minutes of work! Glad I saw this product mentioned on Houzz.

Used the maintenance kit. Worked great. The cleaning solution and scrub pad removed 100 percent of the build up. They look brand new. Customer service was spot on awesome. Responded immediately to all email inquiries, even off normal business hours. They are extremely engaged.

Our company has worked with Diamon - Fusion International for several years. We have found their products to be superior among the "surface protection" products and we have used them all. Customer service is top notch! Very professional. We would highly recommend this company and their products!
