How to sterilize my breast pump?

Abbie
So I received my breast pump and all the parts are already put together but it needs to be sterilized. The instructions say just to boil it. I was wandering can I do that in a pot that iv used to cook? My mil says it has to be an unused pot! Also how long do I leave it to boil? And how do I dry it or do I leave it to air dry?
