After pumping- cleaning/sanitizing ??

Hefinallydidit

Every time after I pump I rinse the parts - shields, bottles,etc and use the Medela Quick Clean bags.  I have only ever fully sanitized the parts once (boil 10 mins) and that was prior to first use.  Is using the quick clean bags after every pump session enough or do I need to be doing something different?  Also, once I return to work and am pumping several times a day do I still need to use the quick clean bags after each session or is rinsing the parts enough until the end of the day when I get home.
