I tried everything to clean the grout on my kitchen floors from scrubbing with a toothbrush to using bathroom grout cleaner nothing helped. I purchased Grout Shield and I cannot believe how brand new my floors look. I am so happy with how this turned out. I purchased the almond and it was a perfect match. I am now ordering the gray for my laundry room. I can’t believe the customers that are complaining about how hard this was to apply. This was so easy to do. Just get comfortable with a pillow and get to work so simple. This product is amazing I recommend it highly.
