Does anyone have an Elvie pump that has tops on how to clean the bottom of the hub? I clean all of the parts in between sessions. And I wipe the bottom of the hub with a damp cloth and spray with sanitizer spray. I’m not sure how to clean the bottom of the hub better though. Milk gets clogged in small areas and I can’t get to it well. Every once and a while I take the hub clip out to clean it better but it is still really hard to get into the small crevices. Any advice would be great!
