Hi! I just wanted to share how happy and satisfied I am with your product. I love your product so much that I even wished I had more floors to do use your product on. To my satisfaction and excitement I had already invited friends and family to look at my clean floors. I have done my whole 2-bedroom condo that has tile flooring all over; from the kitchen to the dining room, the living room to the hallway, the bathroom and the 2 bedrooms. It was a tedious work but I had always looked forward to the results which is amazing and exceeded my expectations. My floors now are giving me that clean look that I have never seen since we moved in. I’m so happy that I found your product. After 4 years of searching it was great to find something that really works. Thank you for inventing this and sharing it with us. You surely made us happy and helped us save some money too. I wanted to buy more, not for me but for friends and family. More power to Grout Shield!
