galt11 Posted January 8, 2021 Share Posted January 8, 2021 Not the kind we all do with our fired casings, but I have a large item that can't go in any kind of tumbler that has both the blue green effluence on it along with the general haze brass gets when it sits around for a while. I would like to clean it all off and make it look shiny new again but haven't had much luck yet. I tried the blue Dillon polish you use in a corn cob tumbler and it was a mild help. I found things like Brasso, but they all contain ammonia, which I was told is bad for brass. THe only other thing I could come up with is a polishing wheel with jewelers rouge. Anyone have any other suggestions. Thanks Adam Link to comment Share on other sites More sharing options...
George16 Posted January 8, 2021 Share Posted January 8, 2021 Soak it in a bucket of Koolaid and then polish it with Neverdull. We used that trick to clean, remove the verdigris and polish all brass firehose stations onboard the ship prior to inspections. Link to comment Share on other sites More sharing options...

galt11 Posted January 10, 2021 Author Share Posted January 10, 2021 Brasso made sense from the name, but when I looked it has ammonia in it and I thought I remembered you're not supposed to use ammonia with brass as it makes it brittle. Link to comment Share on other sites More sharing options...
galt11 Posted January 10, 2021 Author Share Posted January 10, 2021 Thanks for the info. It appears the commonality is citric acid with all the suggestions. I have some Lemishine from the wet tumbling I do for the shooting brass and can use that. is it a soak or do you polish the piece with a solution?
