How often do you sterilize your bottles? Once LO has gone through about 6-7 bottles, I sterilize them by washing with hot soapy water and then boiling them. I've noticed though that after they dry, the bottles feel rough as if theres some sort of film or powder on it.
Re: Sterilizing Bottles
I don't. I just use hot soapy water. I was boiling them like you, but it was too much work. Medela makes steam sterilizer bags that I use for my pump parts and nipples once a week.
