Default Copper rust inside counter-flow chiller?

I have a standard copper tube and garden hose CFC. I ran some star-san through it after I was done brewing last time to help stop it from growing nasty crap inside. Then I left it out on the deck for a week like an idiot. Today I finally got around to purging the copper tube with hot water and to my dismay, a bunch of blue copper oxide came out during the first few seconds. Totally clear after that.

Is this something I should be concerned about?

I think that happened because of the leftover starsan residue. You'd probably want to rinse it with water afterwards. It is an acid afterall. You can also scrub the inside of the tubing by putting a foam earplug in it and forcing it through with city water pressure.

That is an amazing idea!

I'm not taking credit for that one. I read it on here somewhere.

I might have been the one to mention that method a while back.

Another use is as a temporary plug for the CFC tubing when it is stored between uses

Has anyone ever used a freshly-removed earplug to provide the inside of the CFC with a natural water resistant coating? It might also protect from acid intrusion...

Use small ball bearings and you can shoot squirrels with it!

Maybe it's just me, but I think if you use Starsan on your chiller on a regular basis your chiller may find God because it will become holey. I would use a non acid cleaner and sanitizer.
