EP Q: how often to sterilize/ change pump parts

NJshore40

EP'ers how often do you sterilize pump parts?  How often do you change pump parts like the membrane? 

I am currently EP'ing to build supply before my LO has tongue tie taken care of. Not sure how often to do deep clesning.  Currently I rinse parts after each use, wash once daily, and sterilize when i remember to every few days.  I havent changed membrane yet and have been pumping 8-11 times daily for past month.
