Dear Friends: I used to run water from the faucet through the flange (and valve) for a few minutes after each time I used it, then let it air dry. Washed the whole set-up once a day by swishing it in warm soapy water, then rinsed. Never had a problem. I was pumping for a healthy term baby. warmly, Nikki Lee RN, MS, Mother of 2, IBCLC, CCE, CIMI _http://www.breastfeedingalwaysbest.com/_ (http://www.breastfeedingalwaysbest.com/) www.myspace/AdonicaLee ************************************** Get a sneak peek of the all-new AOL at http://discover.aol.com/memed/aolcom30tour *********************************************** Archives: http://community.lsoft.com/archives/LACTNET.html Mail all commands to [log in to unmask] To temporarily stop your subscription: set lactnet nomail To start it again: set lactnet mail (or [log in to unmask]) To unsubscribe: unsubscribe lactnet or ([log in to unmask]) To reach list owners: [log in to unmask]
