How do I remove dried on Bal grout from tiles

[dylanswall]

In a very stupid move, having grouted the ceramic tiles in my bathroom, I didn't remove the excess grout before it had dried. My tiles are now all covered in a thin to middling layer of dried on grout that is proving a git to move.

Is there a quick and/ or easy way to remove it. At the mo I am using washing up scouring pads (the sponge with a rough green top to it) but it is taking ages and not getting much off. Obviously I don't want to scratch the tiles, but is there something a little more heavy duty I could use?

plastic filling knife maybe?

you can buy grout remover & proper emulsifying pads, nothing but a bit of elbow grease going to shift it now
