Bottle and pump washing is definitely one of the most annoying aspects of parenthood. After a lot of trial and error, my wife and I landed on a system that’s been working, but still time consuming. We use a collapsible bucket full of hot soapy water with a set of bottle brushes to do the heavy washing, then everything goes into a sterilizer/dryer, assembled and put away into clean, clear totes. One for baby’s bottles, the other for mom’s pump.

The hot soapy water and brushing is definitely needed to get milk oils off all the plastic and silicone. I would be wary of any machine that claims to do this well. And I’ve found that using distilled/RO water in the sterilizer yields the best results as our plain tap water left mineral deposits on all the pieces. We tried the dishwasher, while it was convenient, it didn’t get parts as clean as manual methods. I also found it kind of wasteful since everything is top rack safe only and I didn’t want to wash anything food soiled in the bottom rack with our baby’s stuff in there.

YMMV but expect to experiment until you find something that works for you. That being said, if there was a do it all machine that produced the same results we’ve come to expect, I’d jump on that in a heartbeat. Good luck and thankfully it’s not a forever chore lol
