yes it has puzzled me to. The reason he used it as we were already in dispute with them about the fact they left the tiles unsealed for over a week and the tiles had started to get stains in them.
Then one weekend we got home and they had put this stuff on them and the grey grout had gone black!
So you dont think Im in the wrong for using that type of bathroom cleaner on them then?
Mmmmmm .. i am inclined to think maybe they have used shoe polish to hide the marks on the tiles before they were sealed....
I think you need to get onto B&Q then...
will you keep us informed please as to how this goes..?
