Bests & Worsts Reviews from Amazon

We had an appointment set up for one of the nationwide service companies to come out and clean and reseal our grout. We have somewhere between 900 and 1000 square feet of 12' tiles. We were told that it would be somewhere just over $1000 to do so; if we weren't happy with how clean it was, they would have to go over it again increasing the price. Fortunately for us, they had technical difficulties just before they were to arrive and rescheduled our appointment, we were going to have to wait 10 more days for them to show up. We decided to do a little more research and we found this product, we ordered 4 bottles and got it the very same day that we ordered it. We tried it in the kitchen this morning, just to see how it works - IT WORKED GREAT!. The grout in front of our kitchen sink was very dirty - we were amazed at how well it worked. I read in other reviews how it was difficult to get all of it rinsed off, I rinsed it twice with a grout sponge and plenty of water. I finished it off with my Shark Crosswave to dry it more thoroughly. We are really pleased with the outcome. It will most likely take us several days to do all of our tile because we aren't as young as we used to be. We highly recommend this product.
