StonePro – Stone & Glass Scrub (1 Quart – 32 Fl Oz) (For Cleaning Granite Countertops, Travertine Showers, Glass Shower Doors & Glass Shower Enclosures)

Photo #1, hard water scale. Photo #2, after using both this product and polishing agents. I gave StonePro 5 stars because it does what it says; it takes off hard water scale. BUT, if there are scratches in the stone, you probably will not be satisfied with the result by using only this product. You would need to rub a long time to get the scale out of any scratches and would probably not be completely successful. You will see a color difference caused by the remaining scale imbedded in the scratches. After using this product to take off the worst of the scale, I then had to polish the area with rubbing compound and then polishing compound to get rid of the remaining scale along with the scratches. That brought the stone back to the same smoothness and shine as the rest of the granite. I do think if I used this product on a regular basis and didn't let the scale build up, the work to remove scale would be easier and the result would be better.

I have struggled for three years to keep the white mineral deposits off my granite countertops and brushed nickel faucets with little success. My faucet areas were an embarrassment to me until this product. I saw the video on YouTube and decided to try it. Great decision! This works but it is taking me some time to get my counter and faucets back it shape. I use it daily and use my rubber gloved finger to scrub it. My bathrooms now look like new and the kitchen is 90% there. I have been scrubbing them daily for a couple of weeks. It will work but you might have to work at if over a period of time.

Bottle came with broken cap and spillage. It doesn't work as great as advertised

This product worked!! I had tried several cleaning products to remove water stains on my black granite without success. It did require some elbow grease but looks great. Pleased with this cleaner.

I bought this to rejuvenate my granite, which has (mostly had) a bunch of mineral spots from our hard water. It worked way better than I expected. It nearly removed all the spots. Since the bottle says it works on glass too, I gave it a try on our shower glass doors, which have been impossible to get the hard water stains off of. It works amazing! Honestly, I am upset that it took me so long to discover this product, because after every other product has failed, I combatted the buildup with a razor blade over the years. After using the product, the minerals were removed so well that now I see all the scratches I made with the razor blade that I couldn't even see before. Oh well. Anyway, amazing product on both stone and glass. Love it!

this stuff really does work. If you have light hard water stains this stuff will remove it instantly. If you have thick build-up you'll have to put some effort in, but you should be able to reduce it by at least 95% if not 100%. Nine out of the ten areas I tried it on were restored 100%, and the tenth area still has some hard water residue left behind that I can't seem to remove. I can live with that. Not trying to be featured in architectural digest over here. When you consider that every other method I looked into either didn't work whatsoever, or couldn't be used on stone, I'm impressed.

It didn't really work on the tile. My tile still has white spots.

I was happily surprised by how effective this product is. I have nickle hardware in my bathroom. Due to chemical cleaners and water I stained the nickle. I was ready to give up trying because I used so many cleaners. I heard of this product on YouTube and decided to give it one more try. This product did not disappoint. It even worked on the spots left by cleaning products. It takes a little bit of elbow grease. Now the more damaged areas are still there but the product made them less visible.
