cleaning after grouting

[Alan.P]

How dirty can the sponges be if you used them to wash off in the first place ? Surely a good battering against the grid and a few clean rinses should do ? Mine have done, well, too many m2 too count and still going, ok, I use one for white and one for grey and mix and match in-between, but my point is they're still ok.
