Cleaning/polishing copper

[TheShadowfox]

Hey everyone. I'm building my own wort chiller out of some copper tubing generously donated to me. It had silicone in the very end of the tube to prevent water from getting in when it was installed before being trimmed off. The silicone has been removed from the outside and the inside has been lightly removed. It's been outside for a bit so it is discolored a bit. Does anyone have any ideas so I can polish it or clean it off in a way that would be safe for beermaking? Also, any thoughts on making this chiller?

Barkeepers Friend for cleaning.

Put fittings over the ends before you start bending or coiling. This will prevent ovaling the tubing and allow you to put connectors on the chiller.

Thank you mates. I'll pick some up and get to cleaning and fitting.

A soak in StarSan solution is also great for removing oxidation from copper.
