What should I do?

are you a v6?? theres an aircraft cleaner for that. search oxidation and youll find some threads

Aluminum oxide provides a thin protective layer that prevents further oxidation, nothing needs to be done unless you don't like the appearance.

I've the same and have seen it on many other cars. It just looks a bit bad, does that stuff above clean it off or just protect it?
