It is of paramount importance to keep your equipment clean and sanitized, not only for health reasons but for the longevity of your QuikBOX.  Immediately after each use, attach your cleaning keg of PBW (and after, Star San sanitizer) liberally through the entire unit. Let the PBW sit in all lines for 20 minutes.  Flush with Star San sanitizer.   Disassemble the QuikBOX in reverse of assembly.  Hang up your Liquid beverage lines to dry.  Remove the ice and water from the cooler.  Store the QuikBOX with the top slightly ajar to allow sufficient airflow to dry.
