Rated 5.0 out of 5.0 by SG Cleaned grout well to remove rust stain
I have a shower with orange stained grout (rust stains) with marble tiles.
This worked great with a brush to get the grout back to the original color.
Very effective. Once it was rinsed and dried, I applied Sealer.

Rated 5.0 out of 5.0 by dave Great stuff for pro use
I'm a tile pro and have been using this stuff for almost 10 years with awesome results. The thing is, I don't know why they have this stuff for sale at Home Depot, it's really a "professional use only" type stuff.

So few things you can use on natural stone, I was very hopeful. After 2 attempts and no noticeable results, I was bummed. Can you tell the difference between before and after shots?

I love this product, cleaned my grout great, I did small sections at the time, wet the grout, let nano sit for a minute, scrub, wipe off and dry, repeat.

Rated 4.0 out of 5.0 by Rollo Nano Scrub worked for me
I started a project a few years ago and just recently got around to finishing it. (like no one has never done that before? LOL) Well, from years of sitting idle the tile and grout became very dirty. The old and new grout did not match at all and the tile is porcelain, the type with divits in it like natural stone and they had dirt ground into them. I though that it was not going to be clean looking ever again, but I had to try something. I bought Nano Scrub and Custom's heavy duty stripper. I mixed the two and applyed to the floor and scrubbed with tile and grout brushes then cleaned with water and repeated the process. It was a long physical process but I was very pleased with the end results. These products worked for me and my situation.

Rated 5.0 out of 5.0 by DIYorNothingGetsDone Floor looks brand new!
Product was easy to apply, used a orbital floor scrubber and stiff brush in hard to reach places. Had to mop 5 times to get all residue off, but well worth the work. Used it on travertine with cream grout, all the little pits and crevices along with grout lines look like I just had it laid. Finished with a sealer, and If i fail on my maintenance will use this product again.

Did not do what it said it would do. I used plain soap water that worked better

Rated 1.0 out of 5.0 by Joe143 Not suitable for use around grouted surfaces
The reason that I cannot recommend this product, is that it really is not suitable for a homeowner to try and use. It is an cutting compound that would only be effective with the use of a buffing machine, hand rubbing was not effective. Worse, as another reviewer said, it distroyed my brown grout. Turned it white, and no amount of scrubbing would remove it. I am having to have grout color sealed to repair the damage it caused.
