I recommend that you take a look at the "Gonzo Wonder Sponge"

It is a dry, small pore, rubber sponge which is extremely effective
at lifting surface dirt without abrading the given substrate.  The
sponges are fairly large so you can cover quite a bit of surface
area but you can also cut them up if you need a particular shape to
reach a corner or work on a small area.  I have used it for dry
cleaning of both flat paper and books that were dusty, sooty, etc.
The company suggests that you wash the sponge when it gets dirty,
but I just cut off the dirty portions as needed.
