How to clean crocodile clips?

I was cleaning my room and found some old crocodile clips, they are all oxidized at the tip, they are like this because when i was like 11 i was into electrolisis, and i used the crocodile clips for that... How incredibly dumb of me :S so How do i clean them? what shall i use? thanks

Maybe try some CLR. Though I'd just toss them. Alligator clips are cheap, is it worth your time to clean them?
