Dr Brown's Natural Flow 통풍 브러시

After wrestling with clogged vent inserts for weeks, this brush finally clears the narrow tubes in one pass—the bristles are stiff enough to dig out dried formula residue without scratching the plastic. It’s become my go-to for the weekly deep clean.

These tiny bristles reach into every nook of the vent inserts without scratching the plastic. Keeps the whole bottle system cleaning up nicely with zero hassle.

Finally, a little brush that actually reaches down into those vent tubes without bending or breaking. The bristles are stiff enough to scrub the built-up milk residue, but they didn't scratch the plastic at all. It makes cleaning the whole bottle set a much faster chore.
