Patch dabbed with soapy water solution is all you need to clean corrosive salts from barrel and gas port. If barrel is chrome lined it is impervious to corrosion, then all you need is just to clean gas port and piston properly. Actual wiping motion from the patch creates suds with soap and water and that is what cleans objects. Just Flushing with boiling water without actually passing a patch through barrel may not get rid of carbon and salt from grooves or gas port. Again it takes soap and water to clean salt from your car during winter at the car wash. Why is it any different with salt and carbon filled barrel and gas piston?
