Sorry to be asking such a novice question but I have some thin powdery dried tile grout on some of my new shower tiles (Not obvious because of the colour but you can feel it when you are in the shower and touching the tiles).
Am I right in thinking its just a matter of elbow grease and nylon scourer or is there a special product I can use to get rid of it?
I don't want to spoil the glaze on the new tiles.
Reason for stupidity, didn't realise the tiler chap hadn't done a very good job of cleaning off the grout until we got back from our hols and started using the shower.
