I take some old rags, t shirts or even old clean parts of under wear and I cut them into small pieces. Then I take those pieces and put them in between the individual twine strands of some twine. Then I soak one with some Hoppes solvent and run it through once or twice. Then I let it sit for 15 min before I run a couple dry pieces through it. Ill repeat it until clean. Then ill run a patch with some oil on and and ill oil down any metal piece on the gun. I don't put many rounds through my guns so I normally don't need a brush to clean it.
