Review on 🧽 Revive Your Grout with 'Make Grout Great Again!' - Effortlessly Clean Tile and Grout from a Standing Position with Pro-Quality Grout Scrubber and Crevice Brush - Ideal for Tile Floors, Kitchen, Bathroom, and Shower Cleaning by Ben Karlen

I thought the standing brush was much easier and quicker to use than going on your hands and knees with the scrubbing brush. I liked the fact that the head was posable and you could change direction. The only problem was that in some places the solution broke down. I didn't scrub as hard because I wanted to be careful when I first used it and the bristles weren't so rough as to damage the grout. Also, I only used the same soap and water that I used to clean the floors and no special grout. In retrospect, I found that some of the areas where the grout had been raised were places where the grout had previously been patched, so it may have been an issue with the grout preparation itself. Now I need to touch up the grout but I think the brush did a good job cleaning up a lot of the grout lines.
