Bests & Worsts Reviews from Amazon

Great product from what I can see. As described it does not work for soap stains, but for plain dirty grout it makes the job as easy as possible. My bathroom grout (white tile/grout) was nasty from the previous owners of the house. About a hour on the floor with this product and the grout looks as good as it ever has while we have owned the house. There are some areas of missing grout and a few small soap stains, but overall this has made the floor look new. Spray it on, give it a minute to soak in and scrub. You can see the dirt come up immediately. Wipe up with water and done. I'll probably make another pass to get a few spots that I didn't allow to soak in properly, but as you can see it does work well.
