I don't have a CFC, but I think you could probably run a couple gallons of boiling hot water through it after you use it to clean it out.
Before you use it the next time, run some sanitizer through it.

I don't have any air/co2 system, so I can't push air through it...How do I make sure that all the wort is out of it and it's clean and sanitary for the next use?
