I don't worry so much about them being tarnished a bit, cuz it won't affect the way the carb works, and it's not like anyone can see them anyway.
I just clean 'em up with a brush, clean the passages out thoroughly, and re-assemble. Been doing that for years.
The only things I clean shiny are the air passages, the bowl vent tube, and the bowl/inlet.
