Excellent, you have to work with it, that is use an old tooth brush to work out the dirt cos it not magic, you wont be dissatisfied if you do your part.

I always read the reviews but try to take them with a grain of salt: is it really that amazing. This one is. I used it first on a small bathroom floor with white grout-or what used to be white grout. First I noticed that it didn't stink. I am super sensitive to smells and this did not have a smell, not even a perfumy one. Other than the spots where the grout had broken up and patches are needed, it did great. Perfect-probably not but that grout is at least 10 years old. It gets washed and I have tried some other products with no difference. This made a RADICAL difference! So I kept going to the kitchen with dark grey grout. What i liked out there was it cleaned the tile in the tight spots near doors and the stove that get grimy but a swiffer just doesn't do enough for. The grout looked better too. My one complaint is the product seems to leave a soapy residue. I don't own a sponge mop so trying to clean that up was difficult. I would suggest making sure you have a traditional mop of some kind to wash the floor with after. Swiffer won't work.

This stuff is amazing!!!

I got this after seeing a review on another site... I have some stubborn stains in a shower and I'm trying to explore options besides regrouting. It didn't help at all with those, which I'd have known if I'd bothered to read more Amazon reviews. I'm glad I didn't, though, because I ended up trying it out on a little spot in my kitchen and WOW! Stuff sucks dirt right out. I gave it some scrubs with a retired kitchen scrub brush, wiped it up with a rag, and it was good as new. I ended up getting carried away and doing a bathroom as well... The odor is pretty strong, so I waited until the kids were out of the house for a few hours. I try to use natural cleaning products, healthier and all that, but this works so well that I figure however many hours it shaved off my life expectancy, I'd have spent scrubbing grout anyway. I'll take that deal.

I just received this. Tried it out on our guest bathroom LVT. Not super impressed. I followed the directions, leaving it on for about 3 minutes. Though somewhat cleaner, not like the areas of grout that are still almost white. I'll keep using it but after using it once, disappointed.
