Is it safe to use Dr Browns Electric Sterilizer on Breast Pump parts?

Cr

Hey all!

Im a new mom... and I’m trying to keep up with sterilizing everything. We have a Dr browns electric steamer, but I wasnt sure if it was okay to put my breast pump supplies in it as well. Some parts wont fit in the top rack so im hesitant to try the bottom rack.

Has anyone else tried this?
