Breast pump cleaning hacks?

Anyone have any cleaning hacks on cleaning your pump. My pump has a milk film over it no matter what. I clean it immediately after use, I mean the longest it’s sat after a use is 30 minutes and that was one time. I use hot hot water and soap and scrub the crap out of it and it still is a film on it. Any advise would be appreciated
