I was following a guide to clean brass without a tumbler (I’m new and want to save money), but then forgot about this brass while it was soaking; it’s been maybe a month, but the video said it should be fine for a couple weeks at least because it’s just lemon juice, dish soap, and water

I was under the impression it would just be “extra clean”, but after rinsing it off just now I noticed weird stains on the brass (some small areas almost look purple!)

Is this just a cosmetic defect, or is this brass dangerous to use now?
