This bottle brush cleaner has been used 5-10 times A DAY for the past year and a half in our home. But truly, it is amazing. The bristles are so soft and gentle on the bottle, yet firm enough to clean it, thoroughly. (We use comotomo bottles) There is a detachable silicone nipple cleaner for the bottle nipple, sippy cup parts, or even to clean parts of a pump. (Both of us pumped more than we wish we had to- more on that later.) I LOVE that this brush comes with a stand. It helps keep it clean and makes it look nice sitting next to your sink. And for $7?! Truly a STEAL!!! Shop it here!
