So I got some free copper tubing from my father in-law. I think it will make a nice HERMS coil. I coiled it around a cornie keg and it fits nicely in my HLT. It has been sitting outside for like 20 years so it's really dirty. Is there anything I can soak it in to make it shine?
Thanks

I'd put it in a bucket full of double strength starsan for a while making sure the interior fills up as well.

I'd soak it in a cleaner first, like oxy clean (make sure to completely submerge though, in my experience you'll have rings of the nasty green stuff around where it sticks out of the solution if you don't), or maybe pbw. Then thoroughly rinse and soak in star-san as suggested by Bobby. You'll probably have to take a buffing pad to it if it's not shiny enough for you after that, but it should be sanitary.

Thanks guys. Oxy Clean soak is under way. After a few hours I'll soak it in some Star-San. I'll post an after pic later.

the acidic nature of starsan will take the tarnish (oxidation) off. as will vinegar, or any other acid. oxyclean, which is basically hydrogen peroxide and some detergents, will not really remove oxidation on copper.

edit: didnt see your post before i hit submit. if you are doing it anyway, please let us know what the oxyclean does to the finish. ive heard people say "no! dont use oxyclean on copper!" supposedly due to similar reasons you dont use it on aluminum... from what ive seen this is not true, but im interested to see what happens here none the less.

I use bar keepers friend on copper. It has oxalic acid. Acid is the way to go. A strong starsan solution could work.

I don't think oxyclean is a good idea but what do I know?

Oxyclean didn't do anything to the tarnish, so I went straight to Brasso and elbow greese. It's working great but it's a lot of work. Thanks for all of the input guys!

One more quick pic. I think it's going to make a nice free HERMS coil! I plan on soldering 90 degree elbows and then male threaded adapters and putting that directly through the wall of the keggle. Does that sound like it would work?

What about the inside? For a HERMS, aren't you pumping wort through it? Who cares what the outside looks like. Now that the outside is clean I would think it would be hard to gauge how a cleaning solution was working on the tarnish inside.

I don't know about the inside. I'm thinking maybe ill fill it up with vinegar and let it soak for a while then pump hot water through it.
