Our Analysis

These cleaning brushes for baby bottle nipples, straws, and sippy cup parts are a great find. They are thin and long, and get to nooks and crannies that most cleaning brushes can't. Made for Dr. Brown's natural flow baby bottles, they still work for all other bottles and straws.

Although the manufacturer recommends you wash their brushes with soap and water by hand before using them, you can also clean them on the top rack of a dishwasher; they are free of Phthalates, BPA, Latex, PVC, and Nitrosamine, and are available in a 4-pack.

We love how easy-to-use and effective these brushes are, especially for cleaning hard-to-reach residue in nipples, straws, and sippy cup parts.


The most commonly cited likes for this product are:

  • Makes cleaning nipples and straws easy
  • Made of healthy materials
  • Great price


User reviews frequently note:

  • Some people feel the wire handle is not sturdy enough
