How do you clean this dang clunky thing? I bought a Pump In Style Original over the shoulder bag used on eBay-I know, hygiene issues ect but I am using my own breastshields bottles ect (which were purchased new) & brand new + steam sterilised tubing so I don't really see the problem. Anyway, the dang bag stinks of cigarette smoke and I HATE that stench!! Is there some way to remove the motor and wash it without like, breaking the thing? How do you clean yours if you own one?
