Plated brass valve

Many metals are despised with superstition. Let’s talk about the endless possibilities. Documentation and academic journals are welcome. Bashing will not be tolerated.

One other thing if you do go the pickling route - be sure to dispose of the pickling solution safely as it will contain toxic lead and copper salts in solution.

One way might be to add phosphoric acid and neutralize. Lead and copper phosphate should precipitate and can be filtered off and disposed of according to local regulations. The remaining liquid should then be reasonably safe to go down the drain. I think. :|
