The product didn't take the stain out, so I am applying it again and hope it works this time.

Rated 2.0 out of 5.0 by CarolinaGirl Maybe helped a little
It was purchased in hopes of removing yellow (water) stains on my cultured marble bathroom countertops. It did help fade them a little. The instructions were followed, which included making a paste and covering it with plastic wrap for 24-48 hours. It was supposed to dry in that time, but did not dry after several days, so I removed the wrap so it could finally dry. I don't know if I will make the effort again, although instructions say sometimes another application is needed.

Rated 4.0 out of 5.0 by Kody Good Product if you understand how to use it.
The product does what it says if you understand how to use it. It is only a powder that you mix with whatever type of solvent will dissolve your stain (i.e. mineral spirits for oil based stain). Then as the solvent dries it will pull the stain into the powder removing it from your stone. Use the guide on the company website to determine what solvent you should use. Mix only that solvent. I suspected I had an oil based stain. So I used low odor mineral spirits according to the instructions on the guide and mixed it with the powder and applied the paste to my granite tile. Then I covered it with plastic wrap and taped it off to slow the evaporation and let it sit until it completely dried.
The only way you can mess up it is to remove the powder too soon or use the wrong solvent. You'll need at least 2 to 3 days to let it dry.
The only reason this product doesn't get 5 stars is that there was no way it would cover the suggested area displayed on the tub (I think it was 3 to 5 square feet). My best was about 2 square feet. It does depend on the thickness of your application. But you don't want it too thin.
I've added picture showing the tile I used it on. I did not order enough, so I was unable to cover all the area needed, but you can see the difference between the 2 areas. Treated side on the left is lighter than untreated side on the right. Its not shadow. Just in case it hard to see I've added arrows. The line is not straight. I'm pleased with the results.

I put this as directed on a marble window sill, and left it covered and taped down for a full 24 hours. It didn't do anything at all as far as pulling any stains or discoloration out of the marble sill. Nothing at all. I've read that poultice powder is the gold standard for this type of work. Perhaps it's just this brand of poultice that falls short. If you want to try a poultice, then I would suggest trying a different brand.

A piece of toast with butter on it was dropped on our granite counter, butter side down. And the result is a perfect outline of the toast. We bought this powder on the advice of HD. We applied it 4 times with limited results.

Rated 5.0 out of 5.0 by Sean Worked on my grout stains when nothing lse did
I had applied a liquid bleach gel to lighten some darker area on my haystack-colored grout in the shower. I had regrouted some of the lines 3 years later and color differences existed, and I thought the bleach would lighten the lines. Unfortunately the liquid bleach pen significantly darkened the lines that I had wanted to lighten. I was unable to remove these darkened areas with additional bleach applied straight, and also hydrogen peroxide.
I finally determined to treat these dark areas as stains and read about using a poultice, I purchased this product, read the instructions in the PDF online. Type of stain determines what you should use to mix the powder with, make sure you read the instructions. In my case I used bleach. Mixed and applied, covered with plastic, and waited 2 1/2 days and the stains are gone. Could not be happier.

Rated 1.0 out of 5.0 by ETXGal Didn't work at all
We had stains under faucet handles that we believed to be iron rust stains. The documentation that we had to find on the internet instructed us to mix with oxalic acid and make a putty-like substance. The company, Miracle Sealants, was no help when we contacted them to find oxalic acid, but we found it through the internet too. No documentation on quantities of each product to use was provided. We guessed our way through. We used distilled water as the liquid. Information stated that multiple applications might be needed. We applied 3 times. The stain did not lighten at all. We cannot recommend this product to anyone.
