I had quite few minor etch marks and a couple of doozies in my bathroom marble countertop (because I'm an idiot and accidentally dripped CLR on it). I had a professional installer come look at it and he gave me a price of $300 to try, but he really didn't want to touch it. So I thought, what do I have to lose by trying this product?? Well, not only did this stuff quickly and easily remove ALL the minor etch marks, it substantially reduced the major marks to the point they cannot be seen unless you know where to look. There is no difference in the feel or look of the areas I treated. The instructions were easy to follow and the product was carefully packaged for transit. I am beyond impressed and eternally grateful. Thank you!

I have a marble side table in my bedroom room and this stuff removed the old water ring eyesore that I thought would never come out. Took a second application but it does work.

This product actually does what it says it will do. It took maybe 2-3 minutes to take out the etch on my marble table. A little goes a long way.
