Like the Rest
The cleaner worked about the same as the other commercial cleaners I have tried.  My grout had not been cleaned for over 5 years and was difficult to get clean with any of the products now available.  The only product I found to work well was an old half bottle of ZAP that I had used the last time I cleaned the grout but I don't think you will find it anywhere at a reasonable price and I'm not sure what is out there is the same formulation.  As for this product the cleaner will probably work for you if your grout is not too dirty and the brush works ok but probably no better than any other out there.
