Hi Efrain, we do Encaustic Cement tiles a lot out here. It’s usually after a tile contractor sealed it incorrectly and they get dirty & ugly or full of grout haze because they’re so porous.

You have to powder hone but which honing power you use depends on the type of finish. 
If the bare tile has a low sheen polish probably a 1200 grit holding powder.
If it’s a real matte finish probably a 150 to 400 honing powder. 
When we clean it we don’t use any soap or any cleaner at all we rinse it and blasted with just hot water. All the cleaners I’ve used if they’re not rinsed off 100% completely they leave blotch marks all over the surface as they dry. 
Then you have to seal it with a topcoat acrylic. Using Matt or gloss finish. If you do use a cleaner and it blotches it up the sealer hides it all. 

These are very tricky tiles to refinish.
good luck

We just did something like this. It was a multicolored cement tile and the grout was blue and left the residue on the surface of the white was really noticeable. We cleaned it with a good alkaline cleaner and a honing powder. Ask Bob from M3 which cleaners he just sent us and he will tell you which cleaners of his we used for this job. I'm not in the office so I cannot tell you off the top of my head

Hello Partners,

 

We have a homeowner that has three different color concrete tiles installed with grey grout that has left the pores of the white concrete looking dirty and dingy. We can’t acid wash it because it will pull color from the darker tiles. Is there any cleaner to remove grout haze on concrete. If this was a marble we would just polish to remove grout haze but we don’t polish concrete. Any help will be greatly appreciated.
