That thing is pretty good right now. But a soak in hot vinegar or even a good dose of lime juice. The acid will eat off the surface corrosion and make it bright and shiny. Then just rinse it off in cold water and don't touch it.
I throw mine in at the end of the boil and when I am done I pull it and rinse it off with cold water. Nothing more. i make sure I don't touch the coils and let it dry by hanging it from the water connections. I do my handling of the chiller from the water connections only. By doing this my chiller will stay bright for months. A bright chiller means nothing to come off in the mildly acidic brew you sanitize it in.
