Cleaning/ sterilizing of pump parts

Hi mummies, I like to know if my current practice of handling my pump parts and milk bottles is correct. 1. After pumping, i will store the pump parts and bottles into fridge immediately (without rinsing) and continue using them for the next pump cycle. I will wash them with soap and UV sterilized them at the end of the day. This is the same for haakaa. Should I be washing the bottles every round or it’s ok to re-use them this way? 2. I will mix a pump of pigeon liquid cleanser to some tap water and rinse/ brush my pump parts and milk bottles. Is this sufficient? If not, how do u wash them?
