put a little lube (your choice) on a q-tip and run through the drum or touch hole and then use a .22 cleaning rod and patch to get down in the breech. Also be very careful with the brake cleaner I use it every day at work and one time at home it took the blue off one of my rugers, sorry I cant remember what brand but It's not that expensive to buy hoppes bore scrubber or similar it's made for guns and its just like brakleen.Just my opinion.
