I recently had some grey porcelain floor tiles laid in the kitchen and in theory they look great - except that every drop of water, smudge of grease, food etc leaves a mark. As a result, the floor looks a total mess most of the time. When I wash the floor, most of the water rings go but some of the grease marks are left.
I've checked the tile info online and it doesn't say they need to be sealed but at the moment they seem to be absorbing everything. I think they're unglazed (is that the same as unsealed?)
I suppose my questions are: first, is it too late to seal the tiles now (i.e. will I just be dealing in the marks permanently?), and secondly, is there a particular product I can use to make the floor look better?
Thanks!
