FILA EPOXYOFF, Epoxy Grout Haze Remover, Effectively Removes Epoxy Residue, The Product Can Be Applied on Vertical Surfaces, 1 QT

Easy to use solution for grout haze . Did a great job of removing grout haze that had been on the tile for several months . Just pour a small amount into a small bowel and use a paper towel or paint brush to put it on the tile and after a half hour rub with an abrasive pad and the haze should come .

We had always believed our cement/encaustic tiles in the foyer were supposed to be brighter/lighter than they ended up after installation with a dark grout. But, they sat as-is for 10 years before I found this. Now, they're back the way they should have been all along.I applied it with a spinning brush on my drill, let it sit for a while, spun the brush again, and then wiped off. In places, I did multiple treatments, getting better results each time. It not only cleared the grey haze from the main body of the tile, but also got rid of small amounts of excess that hadn't been carefully wiped away from the grout lines. I really recommend the spinning brush as this is something you want really well distributed, and mechanical rubbing seems to help. But on any large surface area, you do NOT want to have to do it by-hand.Surprisingly, there wasn't a terrible smell, like from paint-thinner or acetone, and it didn't really bother my hands.Epoxy grout is some crazy stuff, and our contractor had to scrap an entire shower of ceramic tile because they didn't handle it properly and clean it up fast enough. I had lost hope I could clean the dirty haze from these other tiles, but this stuff does the job. You'll need to be patient and thorough, but you'll get results. (Especially if you use it early.)

Worked great at getting out epoxy residue on my tile floors.

If this had the option to add more than 5 stars I would absolutely be adding as many as possible! After having used several other solutions and having made some minor progress I was left with a porcelain tile floor that looked really bad. I had used premixed grout (black) that left not only a blue haze all over the tiles but also left large pockets of epoxy residue as well. I applied this cleaner by sponge (one with a scrunge on the backside). The instructions say to apply it and let it sit for 30 mins, it really only took about 5 minutes before it had loosened up...The floors came out looking amazing!! This was worth its weight in gold !

It’s not working.

Promising product, but for heavy-duty grout cleanup, be prepared to do several applications in order to get all the grout off.I originally thought I could grout my outdoor tile myself, but it didn’t go as planned. I ended up with grout smeared all over the tile that I couldn’t remove. This is the second product on Amazon I’ve tried. At first, I let it his product sit on the tile for 30 minutes and tried scrubbing, but nothing came off. After lightly wetting the tile, I managed to remove about half the grout. I’ve attached a picture showing the before and after from one treatment. I plan to reapply and keep working at it until I can get it all off.

It says that I can use it for cleaning up Resin as well so I will do it but I still have a hard time getting it to work for the Resin.

My hubs and I were sick after the tile contractor left, we had a blurry and splotchy finished left on our dark quartzite new entryway tile. We used a Mapei Flexcolor 3D grout and this left the weird residue, or ‘tile grout haze’ as they say in the industry. After researching everything and testing this on a piece of sample tile I was convinced we made the right decision on this product. The tile is now beautiful and no more haze. Keep it from drying and add water and scrub with the white non-scratch scrubbies, the grout residue shows up like wet Elmer’s glue on the tile surface. E voila! See the pics, the before has some of the haze circled in blue. It did take 2 applications and we used up a whole bottle for 96 sq ft entryway. Vinegar wash afterward and then rinse well. Now to seal it. Thanks to everyone one who left helpful reviews!
