Basic cleaning of the shotgun ejectors can be done without detailed or gunsmith/armorer level disassembly. Old (but clean of abrasive dirt) toothbrushes and or Q-tips (cotton) dipped in gun solvents can be used around the ejector for basic service. Once dried it can be lightly coated with oil for storage and resistance to corrosion/oxidation.
