So here is my story: I was tiling my bathroom wall and it's my first time doing such a big DIY project, which means it could be very error-prone. So when I grouted the tiles, I made a mistake by grouting the whole room first before trying to sponge off the excess grout(once again, HUGE MISTAKE, DO NOT DO IT! You should sponge as you go). By the time I finished grouting, it had become a major disaster as you could see in the first picture attached. It was more than just haze, it was heavy coat of dried grout everywhere! I was really devastated cuz I thought grouting should be the easiest step of this project that had cost me three weekends at that phase. I was going to give up then--I even called up a professional contractor and agreed upon the price to demolish and redo the tiles. The guy won't be available for another week or so, and I happened to see this product at Home Depot so I decided to give it a shot cuz it couldn't be more worse right?
At first I tried to brush off the dried grout using a nylon brush as instructed on the back of bottle. But it didn't work. But one thing I noticed is: when I poured the thing to my basket with some dried grout residue sitting in the bottom, it made a sizzling sound and after 5 min the dried grout in the basket became soft, white cream that came off the plastic basket easily. So I figured that chemically the product should work, but I just need to increase the time it could sit with the dried grout on my wall tile. So I grabbed some paper towels, soaked them with the product, and pasted them to the wall tiles with big chunks of dried grout. I could hear the sizzling sound once the wet paper towel hit the tile, and from that moment on I knew it would work. So after a good 5 min, I peeled off the paper towels, and used a scrapper to work on the heavy coat of dried grout which had become white creamy. Admittedly, it still takes a decent amount of elbow grease to scrap off and for some areas I had to apply wet paper towels three or four times to get rid of the dried grout. So after 10 bottles, 3 rolls of paper towels, and one-day work, you can see the result in picture 2.
So to sum up: 1) this product does work for dried grout, even the heavy sick coat of it in my case, but it takes efforts--don't expect the dried grout would come off once you hit it with a nylon brush; 2) I used 10 bottles of this product and 3 rolls of paper towels to clean off a 110 sq ft of wall tiles--I'm lucky to have three HD stores within 20 min drive radius and I pretty much raided all of them for this product so if your situation is as bad as mine get plenty of them! 3) The other haze remover carried by HD and made by TileLab, I also tried that one but it didn't work that well. But that one is effective in cleaning up the haze.
Hope my lengthy review helps. Good luck!
Pros: Easy to Use
Cons: it has a sewer-like smell so wear a good mask!
This product works very well and removes grout haze on tile. If you are using this with black grout, do not get worried if your grout appears white after the solution has dried. This happened to me and I just about had a heart attack. I called up their 1-800 number and the customer assistant informed me that the white on the grout is from residual mineral deposits. He instructed me to mix some general house hold cleaning ammonia and water and scrub the grout with it to remove these deposits. It worked like a charm.
If they would have printed this simple solution on the back of the bottle, I would have given it 5 stars.
My husband left the grout on top of our floor tile sit too long, probably for a couple of months. We have porcelain tile and used sanded grout. We were scared about using a nylon drill brush attachment. We used a soft/medium bristle and it was very hard to use. This was supposed to be easier than scrubbing. Wore my arms out. This product worked fine. You will have to use it multiple times to achieve success with it if you have let the grout sit as long as we have. It is best to let the floor saturate for one hour in water. I just used it straight from the container at first and did small sections at a time. This works too but not as well. I recommend buying and using this product in a spray bottle.
A family member did a tile job but did nnot get all the haze off from the grout. Once it dried it was almost impossible to remove. Tried this product, so glad we did!

Review 6 for TileLab 32 oz. Grout Haze Remover
Do Not Recommend!!!

No, I do not recommend this product.
We just finished tiling our new home and I had used a similar product from another company and ran out, so I ran to The Home Depot and purchased this product. I assumed most of these type of cleaners were the same. This left more of a haze/film than what I originally started out with and it discolored my grout. It created more work than the previous product I had used. I would not recommend this product.
We tried this product to remove excess grout haze which had been left on for 10 days. Even applying with a scrub brush on hands and knees, this product did very little to remove the haze. We ended up using tilelab sulfamic acid crystals which worked exceptionally well. I gave this product 2 stars, because it might work for applications where the grout had not been left on for such a long time. For our purpose, unfortunately this product was a waste of time and energy.
I bought a house that had grout sitting on the kitchen back splash for 7 years. I cannot believe that the person that installed it never wiped the grout off. It was just covered with grout haze and was so dull and lifeless. This did the trick. Now the back splash looks beautiful.
