Yes, it's Grout Bully, the new "As seen on TV" product that claims to clean your grout in seconds. I've seen this ad a few times now, and maybe I'm wrong, but it seems to me that these Grout Bully bottles are simply the same stuff as that Kiwi shoe polish with a different packaging sticker on it. It seems to do the same thing, the bottles are designed the same (although the shape is admittedly slightly different), with that sponge thingy on top, and they work the same way. So if that's the case, then they don't clean so much as paint your grout. But like I said, maybe I'm wrong.
Here's the suspicious spot; watch it and see what you think:
