Abrasives and acid to remove it.
That slate looks flat so maybe dip’s
And or a brush
Do some testing 
I would try MB22 under a red dot vortex pad

First you need to find out why..Is it a grout film? efflorescence? etc
I have seen this happen with certain sealers as well

Hi partners,

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,
Chris Santospago
