I clean my Omega from the breech. I use boiling hot water with dish detergent in a coffee can. I stick the muzzle in the water and run clean paches on a jag up and down with short strokes. Once the bore is clean I clean the breech threads with a 20 ga. shotgun brush. Last I clean the plug with Q-tips, pipe cleaners, and I clean the flash hole with a piece of telephone wire strriped of its insulation.
