I first put a dry bronze brush of the correct gauge size and run that through the barrels a few times to loosen whatever might be there, dirt, unfired powder, plastic, etc. I then put a 2"x 2" patch and put some Hope's #9 on it and run that through one bore a few times, and then using the same patch run that through the other bore. Put new patch on and do the same over again until the patch comes out clean.
Switch to a wool mop with some Rem oil and do both bores.
I do not use grease on hinge pins, to me grease attracts dirt and dirt grinds into metal. If anything I might use Molykote. the one I use is a graphite powder, and lasts a long time and gets into the pores.
