Not too impressed...
We used this product to clean our unglazed porcelain tile in the kitchen and bathroom. Based on the reviews, it seemed like just the thing to remove ingrained dirt in this textured tile. We followed directions; applied as directed, waited 3 to 5 minutes, removed excess, flushed with clean water, and then dried with a towel. In my opinion, it doesn't seem to work any better than cleaning vinegar, which we have used in the past. Glad that it didn't have an unpleasant, chemical odor though!
