I do rinse the lines out by hand with hot water before assembly. BUt don't sanitize.

Or contaminants that get in post-manufacturing I suppose.  Unless it came in a sealed bag there could be dust, liquids, etc.

Contamination is not a huge deal post fermentation once the beer is packaged - not saying it is unheard of but it's not as easy as we make out soemtimes. And, while we are justified in being concerned about contamination, there is no need to be overly paranoid. Not all microbes are beer spoilers, in fact the vast majority are not. Even so, beer line is sanitary enough for packaged beer. There is absolutely nothing to worry about.

There is also a new chemical called Desana Max that I will be testing as soon as my lines need cleaning and it is a one-shot color-indicating chemical that is supposed to be the best yet, we'll see how that goes in real-world use.

A colleague just turned me on to this (http://www.desana-usa.com/desanamax.html).  Did you try it?  It's a persulfate cleaner.  Looks good (but on the expensive side).

I have used this. A few samples came with some kegging equipment I bought close to two years ago. It works well, but a simple caustic (NaOH) works as well and is much cheaper.
