Reaming a corn cob bowl

When I am finished smoking one of my cobs I ream the bowl with a paper towel is there any other way to ream a cob bowl what is any tips of further maintenence?
FWIW, I use a Castleford when needed. I don't do much to maintain cobs. I smoke heck out of them, and they get a pipe cleaner or reaming when necessary. This works pretty well for me.
