This Review Title is Saves Much Elbow Grease! and the content is: I must say this stuff does an excellent job on tile grout,  with a lot less elbow grease!  My only gripe would be the translation to English from Chinese---really poor!  The review is however, for the product and not grammar or spelling.  In the past we have had tiled shower and tub enclosures, what a pain to keep clean, wish this was available then!  Very pleased with this product..There are other information for this review, one is This reviewer did not purchase it and the other is 0 people think this review is helpful.
