Rated 3.0 out of 5 by 24 reviewers.
Rated 4.0 out of 5.0 by It works but... 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! October 19, 2013
Rated 1.0 out of 5.0 by Don't buy You are better off buying SOS scouring pads...that is what I ended up using to remove the grout and haze off each and every tile. Oh, and this product smells bad, but it is after all a chemical. November 18, 2015
Rated 1.0 out of 5.0 by Doesnt work I followed the instructions but got no results. I even tried letting it sit on the tile for 30 minutes and still no results. Save your money and use Vinegar and Baking Soda instead; It is cheaper and works. July 19, 2015
Rated 4.0 out of 5.0 by If using on black grout.... 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. November 9, 2009
Rated 1.0 out of 5.0 by Poor Choice for frosted glass and stone tiles Worked fine on glass tile. Did not remove haze from stone or frosted glass tiles. July 6, 2015
Rated 1.0 out of 5.0 by Stained! We used this product to clean the tiles after the stained the grout! Be sure to clean immediately after. We now have to re-do the grout because there are white spots everywhere. September 15, 2015
Rated 5.0 out of 5.0 by It works! 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! November 17, 2011
Rated 5.0 out of 5.0 by Works Great!!!! I recently took on remodeling my guest bathroom and the largest part of the project was tile installation. I read the instructions on the tile grout and it seemed like one of the easiest steps. I should have mixed up enough grout to apply one wall at a time but I said to myself, why not. Well that is where I messed up!!!! It started to dry quicker than I could grout the walls and needless to say I had a mess. I scraped most of the excess grout off the walls with a plastic drywall scraper and then spent 3 hours scrubbing the ways. It looked horrible, so the next day my wife and I started to try and clean more off and it was not moving. I remember I saw some haze remover at the Depot so I did my research and saw the before and after pics in the review of another bathroom nightmare and said to myself, that is worse than mine so it will have to work!! I would not even start a tile job untill I had this product in my garage, trust me you will thank me later. (Also, grout is not ment to be "peanut butter" thick It should be wet enough for easy removal at time of application. More like vasaline thick! April 1, 2015
