Stubborn Grout Haze


HO chose a ceramic floor tile against my recommendation. Itís a cheap tile and chipped easily.

Grouted with Mapei Flexcolor CQ and in an air conditioned space and a clean rinse... so the dirty water didnít dry on due to the heat.

Hard to tell in the pictures, but there are spots here and there that arenít coming up easily with a traditional urethane grout haze remover. The Nanoscrub does work with a tile scrub brush but not with a 3x8 white scrub pad. Lot of extra work!

Any recommendations on how to get this up more quickly? First pass with the scrub brush gets 90% and second pass to clean it up.

Final question, have you run across ceramics that are troublesome to clean or is this my fault?

Probably your wash technique got you.

CQ you need to change the water often and grout small areas.

Keep working at it you’ll get it cleaned up. Try a citrus cleaner.

That tile looks prone to having grout and thinset stick to it.

I typically use vinegar with warm water. There are lots of concoctions I have heard of though.

Are you using one of these pads? That is what I have had good success with, but sometimes it takes some serious scrubbing, and sweating.

Test the magic eraser, I’ve seen them change surface sheen.

I bet the "stuff" in the bottom drawer of your toolbox will cut through a good haze

Scrub harder, flip it often, and replace the scuffy pad as needed

CQ is a bitch to get the tiles clean. You gotta wash the hell out of it to remove the haze before it sets. If it sets the best thing I found was a scotch brite pad or a turtle back sponge and scrub the bastard.

Re: Stubborn Grout Haze


I have a friend who does a lot of tiling.

He wipes a thin coat of haze remover on the top surface of his tiles before putting them down. Says it saves a lot of clean-up time.

Did you set that tile? First pic, grout line on the left looks off.
Sometimes with less expensive tile, the sizes vary, and you have no choice. Split the difference.

Re: Stubborn Grout Haze


I figured out a system that works, hope it helps others.

Aqua Mix NanoScrub with a splash of water. Working a few tiles at a time.



4Ē polisher on lowest speed (1000 rpm) with a green scotch pad cut to fit. Used a utility knife to cut it out.



The water is to keep the slurry wet so the scotch pad can do its job. Itís like auto body work, if the compound gets too hot from application, it stops working.

After application, lots of clean towels. Dirty towel gets the first pass then a cleaner towel to finish up.

Tried five other processes before finding this one, which gets most of the haze off.

Re: Stubborn Grout Haze


Next time don't leave the job until the haze is gone. Less work in the end. Micro-fiber cloths are great for performing the final cleaning before walking away too. I just buy the packs at Costco. Sometimes washing them, most of the time they are done for.


Glad to hear it came clean

I don't want to insult your work.. But are they not more worried about the tile joints that don't even come close to lining up?

A glass cleaner with ammonia works on urethane.
