When the cannon is fired on aircraft, the weapons troops will clean the barrels right after flight. It is just like the gun cleaning solvent you would use to clean your firearm. The Crew Chief or Plane Captain would then use a solvent to clean around the gun blast area. They would try to remove as much residue as possible. The reason, it was found late in WW ll, that on unpainted metal the gun residue was very corrosive. If allowed to remain on the aircraft it would eventually eat into the aluminum and cause severe pitting.
This practice carried over when the aircraft started receiving camo paint. That is still part of the check list to clean the area after firing of the gun.
If you wan't to show an aircraft just after flight with a dirty gun fire residue, then dry brushing is the best method. Heavy at the opening and lighter as you go back. Don't forget the gun purge exhaust as well.
