Review (4/5): Saves Much Elbow Grease!
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.
