With an inline rifle I use a mix of 50/50 isopropyl alcohol and car windshield cleaner or windex if you have some of that dollar store stuff. Spritz but do not saturate a patch with the liquid. Swab the bore in short strokes from muzzle to breech then back up. Then a dry patch or two, done the same way. Do this between every shot. Then load up and shoot.

In a traditional rifle I tend to use straight alcohol as it does not cause as much hang fire time I found.
