I saw a recipe for bore cleaner using a version of moose milk with 70% rubbing alcohol, Hydrogen peroxide, and murphy oil soap. Cleaning procedure was standard, pour moose milk in barrel, let stand 30 minutes, empty liquid, nylon brush and run patches till dry patch clean and dry, Spray barrel bore with carb cleaner and run patch til clean and dry and oil barrel.. What does the carburetor cleaner do ?
