Simon.

With normal grout I skip the sponge stage altogether. However much you
leave on the face of the tile, it comes off easily with a coarse rag.
Just more dust, that's all

In a previous house I had a bugger of a job tidying someone else's
tiling and grouting efforts - they left a lot of grout slopped over
faces of tiles (in the vicinity of the grout lines) and it was a
b@stard to get off - I used a grout rake in the end - both to define
the grout into something passable and remove the excess from the tile
surfaces - I could not have done that with a coarse rag....
