Sterilizing breast pump question

Laura • baby # 1 february 2020 👧 baby # 2 july 2022 ❤️

For all of you experienced mamas I need help with how to properly clean and sterilize my Melela electric breast pump.

Do I wash with soap first?

Then can I put it into my sterilizer machine? I have the babybreeza steam sterilizer.

Or do I have to boil the parts in boiling water? I would prefer to use my sterilizer machine if it is ok.

Also how do you wash the breast pump tube??
