I have tried a lot of grout cleaners. Truthfully this is the most effective one I have found. You won't be disappointed. Albeit you are still on your hands and knees with a scrubbing brush, but you can actually see the dirt start to bubble up. You will need to wipe down each area where you apply the cleaner, but I would suggest that if you have a floor steamer, use this rather than just washing the floor with your usual cleaner.

The grout on our kitchen tile is about 30 years old ---( why oh why did we chose ivory/white grout instead of maybe gray or black) so I don't expect it o be really "white" ever again, but Black Diamond Grout Cleaner did a better job of brightening it up compared to all the other formulas I've tried --- and there have been quite a few, including "home made" mixtures. Cleaning grout is at best labor intensive, you gotta apply to all the grout lines, then scrub it after letting it sit about 5 minutes, then rinse and mop -- so do get the brush along with it . There is an odor but it's not obnoxious and will go away after you rinse and mop again. You can do spot cleaning too, in between.

It is so easy to use. You spray it on and 2 to 5 minutes later, scrub it with scrub brush, then rinse it. Good as new.
