DETERDEK PRO Cementitious Grout Haze Remover, Effective Against Rust Stain, 1 QT

This works very well on getting marks from your tiles. But you have to get the technique right. So I learned to moisten the tile, put a generous amount of the diluted product on the tile and wait for 10 minutes. Then scrub vigorously with a scrub pad and then rinse. Where I did less than this it was not effective. But I guess it depends on what mess you have on your tile!

This stuff is amazing! I thought we were in big trouble with all the grout that had dried, but this stuff cleaned up a lot of grout perfect!

I used a particular irritable black ground that severely diminished the clarity of the white tile used, and this product after a few attempts, following the well articulated instructions removed it. The smell was oddly sweet, and non-chemical like if that makes sense so using it was not as bothersome as some others with nasty chemical smells. Overall, the quality is there considering the nature of the products ease of use and lack of noxious orders, however, it must be noted that more intense chemical agents do work slightly better. Nevertheless I think the trade off is worth it if you’re working around children, which I often do.

Worked very well with removing residue grout the workers left on my floor after remodeling my bathroom.

I’ve bought several grout and cement haze removers here on Amazon including this one, and honestly, they were a waste of time and money. None of them even came close to tackling the stubborn haze and messed up grout job trying to DIY a porch Reno. I was about to give up until I tried a product I picked up at Home Depot—and wow, what a difference. I attached a picture and video of the better product. This product worked like magic. The haze started coming off almost immediately with minimal scrubbing. I attached a photo and video to show just how easy it was to use and how effective it really is. What took hours (and multiple failed products from Amazon) was fixed in minutes with this one. If you’re struggling with cement or grout haze that just won’t budge, save yourself the frustration and try this. I wish I had found it sooner—it would have saved me a lot of time, money, and elbow grease. Go get Cement Grout Haze Remover by Aqua Mix.

Where I live we have extremely hard water and I’m scrubbing toilets weekly. This stuff is magic. I drained all the water and let about a cup of this soak all day. The hard water deposits just came off so easily. Now I use an acidic cleaner and it in toilet daily just a tad to keep the hard water deposits away. Wish I had known this 10 years ago

Finished up a new tile project and used this product as recommend for porcelain tile, it required a lot of reapplication and a lot of scrubbing. After which I tried some diluted muriatic acid and it worked instantly without any extra work.

Thank God for this product! I was hesitant, but didn't have anything to lose! We just redid our bathroom and the black grout stained my subway tiles! We tried everything and it would not come off! I literally was crying because I thought all the time and money we put into the shower was completely ruined! I read the reviews and decided to try it and I am soooo happy I did! I bought a scuffing pad that hooks to your drill and I didn't even need it. I used a blue scotch pad and barely applied pressure! 100% recommend this!!
