Gallon Jug Brush
It makes cleaning the 1 gallon jug in my bookshelf kit much easier. I'm not sure if it's the brush not quite cleaning the jug or I waited too long to get the brush. It works, but I probably should have gotten it sooner.
Does an excellent job cleaning my glass carboy.
Huge Brush cleans my gallon jug like nothing else awesome.
If this brush doesn't clean your gallon carboy nothing will. The brush is huge.
Does exactly what it should do. It is what it is, and it is a brush.
