Bests & Worsts Reviews from Amazon

We have white ceramic tile and grout in our bathroom. It has been a decade since we gave it a deep cleaning and it was extremely dirty. I chose this cleaner based upon its star rating and comparison of other products available. I applied the cleaner exactly as the directions state. When I completed my first section (test spot) and let the grout dry after rinsing with water I was extremely disappointed in the results. I had to clean the same section THREE TIMES over to get an acceptable result. I was not expecting grout like new but know I should be able to achieve a lighter shade of off white. When I let it pre-soak for 10 minutes and went to agitate it with a brush, the product was already dry and amounted to just a sticky film. Additionally, the squeeze bottle nozzle dispensed in an uncontrollable manner flooding the tile more that you wanted to or not at all....wasting product. I had to apply more product and not let it sit as long just to be able to agitate the material. The results on the first two of three passes were marginal at best. I tried a 2 other products and then finally tried LA's Totally Awesome cleaner and degreaser. This product worked excellent. I pre soaked for 6 mins., agitated the grout and tile and then rinsed with clean water. The liquid remained wet which gave me more working time before drying. It took me ONE pass to achieve the results I was hoping for and overall was easier to scrub the material. I paid $20 for the Grout-Eez which is three times more for than I paid for the same amount of LA's Totally Awesome cleaner at $7/bottle. Any cleaner I tried worked satisfactorily to clean the tile itself as it is smooth and without texture. This is only the second negative review of a product for me but I felt as though the results this product claims to provide are misrepresented. I'll be throwing away $19 dollars worth of the product I have left. As you would expect, I would not reccomend this product to anyone.
