Will try to resolve this grout haze issue on this Brazilian honed slate on Saturday (pics below).
Apparently it’s just regular grout and they used dry treat to seal it.
Was installed several months ago so I will just try the least intrusive method possible and go from there.
Would appreciate any ideas
Thank you,
