Bought this as an experiment - I really hate dirty shoes, and in the past I've used a combination of dish soap, vinegar, and magic erasers to keep my shoes looking clean-ish. I tried this stuff on a couple different pairs of shoes with mixed results.Overall, I really like the concept of cleaner + brush all in one. It works pretty well too, although I found several times I had to stuff my hand inside my shoe to create enough resistance to release the cleanser from the tip of the brush. This stuff definitely worked the best on the white soles of my slip-on sneakers. They weren't super filthy, but they looked a lot brighter afterwards. The brush could easily handle the textured rubber (which previously would tear up paper towels and magic erasers), and it even got into the crevices of the ruffles on my all-white shoes (see pic). I just wiped off the excess cleanser at the end, and both pairs of sneakers looked great.I also experimented with my grungy suede Lucky Brand boots, which served me well for all of last season but now are only worn on really yucky weather days. I had to scrub pretty hard to loosen up the grime on these, and I think I used too much cleanser, because once it dried, it was pretty stiff, and you could see the watermark from where I stopped using the brush. I then took a toothbrush in some water and dish soap, and scrubbed at the marks that remained. This really helped dissolve the remaining stains, although the suede remained stiff (and a bit lightened)…
