Pump parts cleaning

Hey moms. I recently started pumping and need some adviceZ

Should I be washing my pump

parts after each use? What do y’all recommend when I go back to work?

If I sterilize my parts in my papablic sterilizer in the morning before use, do I need to do that after each pump? Like clean them, let dry, then sterilize after each use?

Also if I’m using a sterilizer machine, do I need to let the bottles and pump parts dry before sticking them into the sterilizer?

Thanks in advance.
