Dull marks on edge of porcelain tiles

[Ajax123]

looks like it could be transit wax

Got there first...

That's what I thought so I should be contacting the tile shop. Such a nightmare and strange that its only around the edges of the tiles. Should I be pushing for the tile shop to be footing the bill, so far only about 1/4 of the total tiles have been laid so I know we can return unopened tiles but what about the tiles laid today? Not to mention the tilers time etc.

Discuss it calmly with the tiler first IMO but do it before he starts laying more just in case it is a tile issue....

It has a rough texture compared to the rest of the tile which seems to have a greasy film on it. Would this transit wax only appear around the edges?

Try something like white spirit on a tile in a suitable area. If it moves it then it will be worth getting some transit wax remover from the tile shop.
