How do i restore this engine bay?

http://ift.tt/2tiSHcQ'm trying to restore this bay's paint, metal, and rubbers. its got some kind of 'chemical staining' per say. Looks like its stained into the paint and ate the finish on the aluminum.i figured there'd be some restoration sages on this sub, and i could really use advice. via /r/cars http://ift.tt/2sNMXnC
