My husband uses huge water jugs for work, and this brush cleaned the cloudy corners I used to miss

I got one for my mother, and she says her tea flask looks clear inside again after one wash

After my protein shakes, this brush gets into the curve near the base where my sponge never reached

I keep it hanging by the sink, and after smoothies it scrubs the bottle base clean in under a minute

This long brush reached past the narrow neck of my camping bottle and cleared dried drink mix from the bottom

The angled head helped me clean my tall glass carafe without shaking soap water around like I usually do

I use it every Sunday on our fridge water pitcher, and the handle feels sturdy while I scrub the sides

It cleans my travel bottle really well

Nice brush for my wide water flask

I like using it after iced coffee
