Title: Amazing!
Review: I was so excited to receive this product. We're moving out in a few months and want to keep as much of our security deposit as possible. We got a puppy while living here who is gated in the kitchen while we're gone. She's messy of course and spent many, many months pooping all over the floor. As much as I would mop, the floor always looked dirty because of the discolored grout. You could see the dramatic difference when you looked at grout in a spot that wasn't traveled over. Anyway, this product did exactly what it said it would do and it didn't require lots of back-breaking labor. I used an old toothbrush to scrub the grout. It also smells pleasant - not like harsh chemicals. I tested a spot and want to do the whole kitchen floor. A+! Would definitely re-purchase.
