Spot-X Hard Water Stain/Spot Remover - 7 Ounces

The product is great and really removes the water stains (5 stars). However, this seller didn't provide the cleaning pads that should come with this product which is why I'm giving this 3 stars. Make sure to read all the details before ordering. Thankfully, I still had the cleaning pads from a previous order.

Works great! We have really hard water and most products that claim to remove soap scum and hard water barely clean anything off our shower doors. I was skeptical at first, but once I saw how well it was working I couldn't have been happier with my purchase. It didn't remove all of the build up the first time around (probably about 95%, which is a great amount to me), but if I would have gone back over it a second time or worked at it a little longer I have no doubts it would have come off.

I'm just amazed how great this product is.After 18 years of hard-water (in Sammamish, WA area) ruining our shower glass enclosure to the point of not being able to see through the glass any more and sprinkler system leaving water spots on the kitchen window and spending hundreds of $ on different products at Home Depot to get rid of the issue, finally I found Spot-X and used it with "Power Scrubber Scumbusting Scrub Pad" attached to my drill (https://www.amazon.com/gp/product/B00FL9VWQQ/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1).I must say, it 100% removed every Hard-water spot. My shower glass looks like day-one (brand new) 18 years ago and the kitchen glass is spotless. I also used in toilet bowl to get rid of the hard-water ring. It worked too.I must say, the only reason I took the time to write this review is to help others who are dealing with the same issue I had. And also many thanks to those who wrote reviews to help me give this product a try. This product practically saved me thousands of $ (as I was thinking to replace the shower glass, tiles, etc).I cannot thank enough those who came up with this product.

I spent hours researching the best hard water remover. However, I tested it on my built-in soap dispenser (from my newly renovated kitchen) and it stripped the wrought iron finish off and now it has a copper tone...Very disappointed! They should have to replace my soap dispenser.

This might work on some glass or counter, but it did NOT work on my shower with or without the pad. It makes such a mess too. I tried using a lot, using a little, and putting a heap of elbow grease in to get the spots off, but it just did not work. My shower door is only a few years old and I have hard water, so there are hard water spots. If it could not get my hard water spots off, I don't consider it a good product.

It washed away some stains on my shower room glass door, but not completely clean. I'll have to keep looking for better solutions.

Works but VERY expensive

This powdery substance is a miracle product, no less. I can't tell you how many things I had tried to get hard water stains and soap scum off my glass shower door: baking soda, lemon juice, harsh chemical agents, vinegar... All produced little to no results. Just as I was ready to buy a $20 spray cleaner (which actually has 5-star reviews on Amazon), I came across Spot-X. Priced around $5-$7 with free shipping on Prime, I thought it would not be much of a financial loss if it didn't work. The reviews were also positive and I placed the order. The only thing I regret that I had not found it sooner. Spot-X removes scum on a first application and with no effort! Put about a teaspoon (or less) on a damp cloth and let it turn into a paste-like substance. Apply it to a wet surface and scrub. The soap scum and hard water spots will come off immediately. Guaranteed. As long as they manufacture it, I'm their customer for life.
