Diamond Seal Systems Forever Brilliant Made in The USA. Best Glass Restoration DSS Bath Kit Direct from The Manufacturer

Doesn't work on mineral deposits that have been accumulating for many years.I tried, literally, every possible product to remove the deposits. Even tried 600 grit wet sandpaper in a small corner.. which worked after a lot of effort.Decided to give this a product a try as a last resort based on their video.This product did nothing at all to the deposits but... I had deep water stains on my car windshield and windows so used the product there and it did a satisfactory job.In summary, for long accumulating and tough deposits give this product a pass. Hire a professional and get it done correctly.

2.5 years later this sealant is still going strong even without regular maintenance with the spray. We wipe down the glass after every shower with a microfiber rag and recommend this over a squeegee. Note that this product was applied to the shower doors 9 years, yes NINE years after we built our house, so the glass was in pretty bad shape. It cleaned the glass to new condition, and the sealant has continued protecting it from water since application 2.5 years ago. We have a lot of minerals in our water that builds up on the fiberglass but not on the glass doors because of this product. This shower is used a minimum of once per day. It did take a bit of muscle to get the glass to clear again, and the electronic scrubbie might help with that; I just used muscle. I highly recommend this product. Best purchase ever!

we used on a new shower door a couple weeks old. Before finding this we sprayed with rainx until we found a longer term solution like this. Even after these two weeks, once we cleaned the shower gladd with stage 1, it was so frigen clear it was legit better than new and we almost thought of skipping step1 since it was a new shower. DONT! Its worth the labor

I spray my glass with a standard shower cleaner after each use but have some cloudy buildup on the shower door & adjacent panel now. After trying all the home remedies I could find online without any success, I bought the Diamond Seal Systems kit hoping it would save me from having to replace the glass, which is nearly 3 years old. The end result is a tired arm, glass that looks the same as when I started and a few hours of scrubbing & buffing that I can't get back. Not sure what condition I have compared to the other reviewers with success but this did not work for me.

Diamond seal is the only product that makes my shower doors spotless. It was recommended to me by a professional housekeeper. I spent so much money on products that did not work. Its is a remarkable product.
