One always finishes such a job with a thorough flushing with a good solvent,
then wipes down the surface with an oily cloth.
A 1000 fine emery cloth band is the standard material used in the final stage
of cutting the journals on a crank. Not wet-or-dry. Of course, in the final
stage the journals are wiped with a solvent and finally a oil cloth.
A deglazing hone is used in exactly the same manner. In the old days, when
for example one rebuilt cast iron brake cylinders, you used a special set of
hones that were about 1000 fine. Same procedure as above.

All abrasives work by donating some of the abrasive material to the process
of removing what ever they come into contact with. In my limited
experience, emery cloth does shed particles quite quickly: good quality high
number (420 and above) wet and dry will still shed bits, but at a reduced
level and the particles will be small.
A hone will also leave its own detritus, although it will be very fine
particles.
I think the message is that after you finish the rust removal, make sure you
flush the bores and any orifices nearby with liberal quantities of cleaning
solvent.
