BuzzFeed Shopping Editor Natalie Brown put this baby to the test and here's what she had to say: “This thing works little miracles: I cleaned about half of the grout in my bathroom in 40 minutes until it was back to its original, sparkling clean cream color, and honestly it was no effort at all. I literally sat on the floor, dipped the bristles into a castile soap solution (2-3 drops of soap + 1/2 cup water; but you can use almost any cleaner of your choice), and then ran the mop lazily back and forth over a 6 -inch section of dirty, dark gray grout – and it only took about 30 seconds for that grout to go from dingy to light. At first I used the special grout brush, but then I decided to try the standard brush and that seemed to work just as well in my opinion!“Check out their full Power Scrubber review.
