I didn't know what exfoliating meant at first, either.
When Googling, I read somewhere that one cheap way of doing it is with a scouring pad - as in those green Scotch pads. (You also don't have to be embarrassed about going up to the checkout person with a loofah or whatever - trying to pretend it's for your wife/girlfriend. ;-)
Anyway, that's what I've been using so far.. Since it's quite rough when new, I've just been using it very lightly until it starts to soften up a bit.
