I'm going back to work soon . Can the mummies share how you wash the pump parts in the office and how to transport the milk back home fresh ? What kind of cooler bags do you use ?

I have pigeon washing detergent and a brush in office so I will wash after every pump, before my next pump I will sterilize with hot water. The EBM will be kept in my jujube fuel cell in which I have a medela ice block and autumnz ice pack which I will place in office freezer once I reach office until my 1st pump. EBM will be in my cooler bag on my desk the whole day as my office fridge stinks. When I reach home in the evening and sometimes at night, 9 plus my EBM still cool and Ice pack still not melt.
