Diamond ShineDiamond ShineProfessional Hard Water Cleaner - Lime, Calcium, Rust, Water Spots, Soap Scum - 10 Ounces

Finally, something that quickly and easily removes hard water and mineral deposits from my shower door. I just used one of those white 3M-type pads while the water was running and the whole process took less than two minutes. Seemed to help when I did it in sections and rinsed right away. Worked so well that I also touched up the 25 year-old shower floor, then also cleaned up some stains around the drain in the porcelain sinks. Seems like a little bit of product will go a long way too. May even try it on my glass stove top.

This product is amazing have used CLR cleaner but have never had the results like this. Sprinklers hit my windows sometmes and leave hard water deposits. Used this crean with a soft plastic brush disk on a drill and results are great.

This product does remove water spots from glass. Works well on my pots and pans and tub too. Great product overall but kinda pricy for a small bottle.

I was hoping this would deal with the hardwater stains on my tub. It worked about as well as every other product that helped a little but didn't live up to expectations.

This works pretty good. My other product that I used was better. This takes more work but works. Make sure you seal your glass after.

Heard it from a friend, what’s that you ask. “Diamond Shine restored my chrome rims, even my BBQ Grill.”. I had to try it out for myself and boy was I amazed. Diamond Shine brought my 20x9 Chrome rims back from the brinks of junkyard death. After a quick wash, an application of Diamond Shine, a rinse and drying. My truck and I were heading down the road turning heads.Don’t believe me, pick up some diamonds (diamond shine that is) and get to cleaning. You’ll become a believer.Yes this cleaner works for household applications as well.

Didn't work

After reading some of the reviews, I was hoping I had found a product that would help me with the hard water stains I feel I am always battling in my shower. Well this product was no better than any of the other products I tried and it is expensive. One of the reviews I read suggested Bar Keepers Friend did a better job. After this product was a disappointment. I tried Bar Keepers Friend and I definitely agree it works somewhat better and it is definitely cheaper.
