Clean pump

I put mine in a sealed plastic bag in the fridge in between sessions and washed once a day 🙂

I do same as Sarah. Sometimes I clean every other session, just depends how much time I have.

I run my parts they hot water after every use

I wash the flanges and bottles with soap after every use and run everything through the sanitizer every 24 hours.

You don’t have to clean between each pump. You can refrigerate them.
