I use water & mind detergent to clean the pump, and use 奶樽消毒煲to sterlise. Do not boil the soft funnel, as some of my friend had the experience that the soft funnel had deformed after boil for 5 minutes in boiling water.
After feed the baby, you can pump out more milk & store the milk in refrigerator, then use warm water bath to reheat the milk before use. I has purchased some Medela disposable milk bag for storage. which is easier for me.
You can use boiled water to clean the pipe and then use the hair dryer to dry them. Also, you'd better use cotton to clean the opening after pumping each time.
I use a milk bottle brush to clean the long pipe and a small brush (for cleaning silicon nipples) to clean the yellow part.
I wash it (and then stream it) once or twice within a 24 hr cycle. For most of the time after using it, I use 消毒紗布 or 乾綿片to wipe the opening of the pipe and then put the whole pump into an air-tight plastic box and store it in the fridge (the area for storing dairy products). Before sleeping and sometimes in the afternoon I'll clean it and sream it after pumping.
