There are smoother and rougher tile surfaces. When getting tile put in my house I've made something of a point of avoiding the very slickest/smoothest tile.
I feel only rocky texture will be satisfactory after a year. Or is there any chemical that can safely strip the soaps and other fatty stuff from the mineral?
My roughest and lightest tile--which has to be replaced for other reasons after a couple decades in what we call a mudroom in New England--could probably be cleaned but would be a procedure. In general, darker and just somewhat textured tile seems to work pretty well in less-trafficked areas.
