White vinegar will remove bluing and I suspect case colors, too. I cannot think it should be used as just a cleaner.

When I want to clean something well, I use an old dental ultrasonic cleaner with powdered Spic and Span. Then rinse the metal off in ultra hot water, blow off water with compressed air and then lubricate as needed.
