Spot-x Hard Water Stain and Spot Remover, Whit Micro Fiber Cloth

OMG I don't know what to say about Spot-x Hard Water Stain and Spot Remover!I had hard water stains on the rear glass of my 2001 Cadillac Seville STS, since I bought it in 2003 from someone in California. Over the years I've tried about six products to get the hard water stains off the rear glass with no results. This included using rubbing compound and even other commercial available products that said they could remove them. I even talked to some sales reps from these companies that insisted that their product could remove them and they would even send me a sample to try on an area. Well to say the least none of these products ever worked.Well here comes 2014 and I'm surfing Amazon buying random things and I run across Spot-x Hard Water Stain and Spot Remover and I just have to give it a try. I figure the worst that can happen I'm out a little bit of money if it doesn't work.The directions are simple enough to follow so I gave it a try on a small 2 x 2 area of the rear glass on my car. Well within a few minutes if not less, I was amazed. The hard water spots that were there for over 10 years were gone! At first I thought that must have been luck and tried another spot this time larger. Again, same results, the hard water spots were gone! At this rate I was amazed that I actually found a product to remove these after all these years.As it turns within 30 minutes of trying this product I had completely clear glass. I really wish I would have taken and before and after picture as the results were unbelievable to me. If you've had hard water spots on the glass of your car for years give this product a try as it cant be any worse then the other ones you've tried.The best part of the product its easy to use and doesn't require much work. I didn't have to rub really hard to get the spots out. I just mixed the powder with some water until it was a thick paste. I then just gently rubbed the glass for a few minutes and then washed it away with clean water to see my results.

toooooooo good! its some type of sand/granules.how does it work:superb! Its like some sand/granules so when you rub it on the surface it takes off all those hard stains. So simply take a little powder on the clothe, damp the area and rub it on the affected surface! it works great!we just moved to a new place/ brand new house. we were using the shower but never bothered to clean it and its been a month. so stains were pretty hard to clean, tried many products from Target/Home Depot nothing worked but this one worked just fine. Little bit of effort but its worth it.

Takes hard water stains off glass and leaves it sparking clean. The hardest part is actually getting the cleaner off the glass since it's not safe to eat and not particularly water soluble. Need a bottle brush for that.

Was not what I expected did not remove water stains from glass

did not work to remove all of the stains

Does not perform as advertised. Did little to remove hard water stains.

I have used this a couple of times and it does quite well. I used this on by glass shower doors that were completely hard water stained. I had tried everything to remove, including Ajax, which helped a little. I eventually ordered this after seeing reviews and plan to always have this on hand now. This with some elbow grease and the proper scratch pad and my doors look new.

I LOVE it! It took off 2yr old water marks from my glass door and metal frame. I couldn't believe my eyes. All you do is dampen the cloth, pour a small amount of powder and scrub away. It does take a little work but it is well worth it. The amount you need is very small and this bottle will last you a while. I cleaned the door a few months ago and there are no visible stains up to date. I highly recommend this product. The bottle will last you through several applications.
