Getting ready to use a copper immersion chiller for the first time on saturday. Anything I have to do to clean it before I use it? It doesn't have any of that green corrosion that copper sometimes gets, but it's slightly dull. I soaked it in oxiclean and it came out looking the same. It smells really strong of... copper (duh). Between my aluminum kettle and the copper chiller, i'm paranoid about metallic off tastes in my beer.

I dip mine in starsan for about 5 minutes to get it all shiny and to make me feel better. Then i stick it in the kettle about 10 minutes before the end of boil.

You could try a vinegar solution. That should clean it up some.

1/4 cup white vinegar and 1 tsp salt creates a mild acid to clean copper.

I stick mine in Star San to sanitize it and it also cleans it up and makes it nice and shiny.

i tried some vinegar but it didn't seem to do much. Should I boil it with it, or just wipe/scrub it?
How do I know when it's clean?

I've used a mix of equal parts vinegar and hydrogen peroxide. It will turn the solution green and your copper nice and shiney. I usually soak parts in a bag, but that would take a large bag and a lot of solution for an immersion chiller.

Be careful using the vinegar and salt mixture; it can eat through copper pretty quickly if you use it over and over and let it sit too long.

In my opinion, some soap and water to scrub off the flux and dirt the first time is all you need. As long as you hose it off after each use and keep it from getting dusty or dirty between brews, there's no need to clean it any more. The 10-15 mins it spends boiling in the pot is enough.
