How do you clean your keg lines after a batch of ginger ale?

I had some ginger ale on tap for a while and finally switched over to a lemongrass saison I brewed up. I feel like i'm still getting some of the ginger ale flavor coming through even after soaking the tap in pbw and letting pbw sit in the lines for a while.

My next step is to hook up my chugger pump to the serving line coming from a bucket of PBW water and then recirc the line for about 15 minutes before doing several flushes with water.

I have some BLC as well. Think that would work any better than PBW? How do you clean your lines after a soda?

I hooked an IPA up next. No hint of ginger is going to get past all those hops!
