From Medela's website:

"The Medela Pump In Style Advanced has an internal diaphragm that cannot be removed, replaced, or fully sterilized. Therefore, the risk of cross-contamination associated with re-using a previously owned pump such as the Pump In Style cannot be dismissed, even when using a new kit or tubing." 

(http://www.medelabreastfeedingus.com/tips-and-solutions/14/can-i-buy-or-borrow-a-pre-owned-breastpump)

According to Medela, there is no way to really clean or sterilize the diaphragm, and supports the experience of some on this list who have found moisture/mold inside the pump. AND directly contradicts what the sales rep told the original poster.

(who has been using the same pump on and off for ten years with 3 different children and is now somewhat horrified to think what might be inside it!)

I'm thinking of the mom pulling her own pump out of the closet after 2 years and a new baby, or the mom who insists on using her sister's PIS (that was "only used twice"). Is this a 10% bleach kind of thing or is there a better way? And I guess there is no way to remove that white diaphragm to really clean it well, right?
