I need some advice , I looked at a laminated porcelain floor at a dealership that the cleaning crew used a solution that had phosphoric acid in it and looks like a etch all over some of the tiles (like a spill pattern). I have polished a few laminated porcelain tiles to give them a high polished look when the installer mess up but can these be honed with powder to give a uniform look? The etch is minor but after cleaning it slowly collects soil and darkens quicker then the rest. These are 18x18 tiles honed finish.

 

 Thanks Phil
