ammonia and copper react to form the cuprammonium ion, formula [Cu(NH3)4], a chemical complex which is water-soluble. What occurs is any scratches, cracks or nooks and crannies get the ammonia inside them and as the reaction occurs it erodes the copper out of the brass alloy. Then when one washes the ammonia solution off the copper is washed out as the cuprammonium ion
It sounds like your answer is for an extended exposure. I am questioning a 2 hour shake to clean and a detergent wash. Would your advice still hold true under those terms?
I have a question about cleaning brass. I've noticed some comerical brass cleaning additives make the statement "contains no ammonia." Does ammonia weaken the brass? What would happen if I added a shot glass of ammonia to my walnut shells in a vibratory shaker?
It's stupid to talk out your ars and down your nose when a guy asks for help from experienced people. Why even bother to respond?Yes, exactly it is stupid. Google returns only about oh, 50 pages of results with more info than you can shake a stick in the first page. It's 2020, who wouldn't Google search first and then, and only then, ask a question they couldn't answer? Keeps it lively.
Come on man...right?
I read it as looking for clarification but that's fine, be a dick.In that case, go for it. You've gotten your answer, but apparently aren't satisfied w/it.

Good point.I like that it has a surfactant in it
