PSA - if you need to take off some mild corrosion or aging on small metal/chrome bike parts, maybe try 2 days in Evapo-Rust, not 2 weeks. So I stuck these small shifter parts in, just to kinda clean them up and make sure we didn't have any tiny surface rust. Well, I sort of forgot about them, then I was gone on a work trip. Brought them up to work on some shifter stuff today, and lo and behold, they were discolored. To be honest, the color is kinda cool, but not what I was going for, and has taken quite a bit of work to get this discoloration off the parts. So, of course, way more work...just like everything else on the entire build, so it figures.
Discolored vs cleaned up. Whoops.
