I've always made my own patches for shotgun cleaning from whatever old cotton material I happen to have lying around. My usual routine is to use a large solvent-soaked patch in the slotted tip for initial wetting down, followed after a bit of a wait by a couple of passes with the bronze brush, and then with a few patches wrapped over the swab so they fit reasonably tightly. When one finally comes out more-or-less clean and dry, I finish up with a clean one with a bit of oil. Using the patches over the swab keeps it clean longer - when it gets too dirty, I just wash it with detergent.
