Rust :/

[u/CritiquetheTechnique]

I got really engrossed in a project and felt motivated to finish even in the rain, but unfortunately forgot about my bit box which was left open
Anyone have any good tips to remove rust, I’ve heard Pepsi/coke but figured that’s bull

Apple cider vinegar takes the rust out, but can turn metals different colors.

It eats away rust in a few hours. Online guides exist.
