I've been googling on how to clean green patina, or rather copper
sulfate oxidation from come metalic components. All I can find is how to
add it, not remove it! Evidently, this green substance is desirable for
certain applications, such as artwork. What can I use to remove it from
some copper hinges?

There's copper cleaner used to clean pots/pans. Bar Keeper's Friend
should also work. Both can be found in grocery and hardware stores.
Both are very mild abrasives.
Follow directions. Use old toothbrush for tight spots.
