You don't want to clean a copper chiller so it is shiny - if you remove the dull color (stable oxide), the metal is more likely to react and form the toxic blue-green oxide (verdigris). http://byo.com/stories/projects-and-equipment/item/1144-metallurgy-for-homebrewers Copper is relatively inert to both wort and beer. With regular use, it will build up ...
I don't worry about it, other than rinsing sweet or bitter wort off of the copper manifold and chiller. The low pH of the wort will clean off any oxides, and copper is readily consumed by the yeast (it's an essential nutrient), and it's all pre-boil, so a hot-water rinse is all that's necessary, assuming you're doing all of your cleanup at the end of your ...
I clean my home made copper manifold and immersion chiller a couple of different ways. The manifold get's boiled before and after use to remove all the sticky sugars from inside the tubing. The immersion chiller get's rinsed and then boiled in the wort before chilling. It's rinsed with very hot water afterwords and sometimes I give it a clean with a soap ...

I was going to suggest StarSan as you did in your question. Put it in and come back tomorrow. Actively cleaning it yourself is ones on prerogative, but I have other things to do. Which is also why I soak my other stuff in PBW and comeback the next day, rinse and put away.
Do not use copper with acidic foods High concentrations of copper are poisonous and acidic foods, especially carbonated foods like beer, will suck it out of the metal. The FDA explains: 4-101.14 Copper, Use Limitation. When copper and copper alloy surfaces contact acidic foods, copper may be leached into the food. The acid that results from mixing ...
After every 10 or so brews, I soak mine in powdered brewery wash (PBW), goes in with a rainbow of colors comes out looking like new. Plus, no elbow grease required.
As long as it isn't rusted and/or leaking, you're probably fine. If it were me, I'd take some polish to it and make sure to rinse it thoroughly afterwards just to be certain. You may not have to, but my perfectionism would scream at me for any mistakes in the flavor of the beer, even if it had nothing to do with the chiller. I vividly remember having to ...
Make a paste with Bar Keepers friend and rub it all over the surface of the chiller wait 15 to 20 mins then rinse. It is cheap and the oxilac acid cleans the copper very well.
If they're not attached to anything, maybe soak them in PBW for 30 minutes? If they're attached in a system, run PBR through the system for a few minutes. Either way, then rinse, sani, and brew!
