https://spectra-baby.com.au/wash-sterilize-clean-breast-pump-parts/ interestingly according to spectra website, washing of backflow protector is not necessary to do it each time unless there is milk condensation
I would wash everything as there could be milk inside too
Any part that touches the milk in any way, needs to be washed.
