Cleaning breast pump parts

Ch

Is it okay to put them in the top rack of the dishwasher? I've been ebf my son for 12 weeks but I'm brand new to pumping because I haven't had much success with it, honestly I'm lazy and even though feeding him from my breast is time-consuming the thought of sterilizing all these little pump parts a couple of times a day is completely unappealing to me. So what's the easiest way to do it? Thanks in advance!
