Cleaning Keg lines after strong flavors

[naptowndon]

To clean my keg lines i normally use PBW or Oxi solution in my keg cleaner pump or empty keg and push through the line. I follow up with starsan. This worked fine until my jalapeño cream ale. The oil in the jalapeño still leaves that flavor in the line. Just a hint. I had a similar situation after making root beer with a picnic line. Any suggestions? Any kind of acid or stronger cleaner that may work?

My suggestion is to replace the line. At some point trying to clean the lines is going to cost more than installing a new line. Unless you have something like Brewmaster II glass lines, very strong flavors will leach into the lines.
