GREAT PRODUCT!
I first bought this product from their website. I tried it on my tile floor to see if it would remove the grout that had built up over the years. I just did a few squares to see, and this stuff really removed the grout. I am here on Amazon to buy more, so I can complete my entire Kitchen. I don't usually write reviews, but I was impressed at the job it did. You can really tell the difference. I only did four tiles, and now, I must do the rest, cause those four makes the rest of my floor look really bad! Haven't tried it in the bathroom area, so I can't comment on that part.
