I use Shooters Choice Xtreme Cleaner. Let it sit in the bore for about 10 minutes. Then run 2 dry patches down it. Then put some on a brush and make 25 passes with it. Then use a dry patch until it's clean. Then run a patch of denatured alcohol and then a dry patch and you're ready to go.
This was after 5 shots. You can see how the plastic from the wad builds up.
