Picked up a little 18x12 surface plate.
No idea what the best way to clean this is without doing more harm than good, although I've no way of telling how flat it is to begin with.
Still, I assume going at it with the DA would be a bad move!

Looking at that I'd get a wire cup wheel from screwfix and have at it with a mini grinder. It won't change the physical dimensions but it'll bring the surface up nice. 5 minutes work and you'll have a working setting out plate. A rub over with a fine stone might even render it good enough for normal surface plate duties.
