What would get out these marks/stains?

[Otis Ascot]

Hello everyone, my first post here. I have recently had these tiles laid: Classico Fleur Silver Pattern Tiles - https://www.wallsandfloors.co.uk/fleur-silver-tiles?web=1&wdLOR=cA29807BE-580F-4591-9014-1033D29BEF76

They are in my bathroom, on the floor of the wet room.

They have always looked dirty with marks across the tile. Do you have any ideas what the marks might be and what might clean them? They are ceramic.

Many thanks, very much appreciated.

Otis

Lithofin Powerclean should do the trick
