Let's talk about RUST! lantern style

Описание: rust issues that plagued a few of my restored lanterns. what could the causes be? acetone? flux? steel wool dust? i test out evapo-rust (not a sponsor) on a few very rusty lantern parts. any wisdom or opinions? leave a comment. my new camera mount kept turning off my phone.
i will put a link to any updates on this subject here: ( 10/5 I just found a "no clean" Flux. sounds like an important step) as of now, no other update 10/5
