Growler Brush - Gallon Jug Brush

Works great for growlers and touching up cleaning in my 14 gallon unitank

Its a brush, it works, pretty straight forward

I'm using it on my 1 gallon glass carboy. Reaches all areas of the jug including the shoulder. Works great.

It is probably my fault and I ordered the wrong item, but this brush is of no use to me at all. It will simply not fit into the neck of the bottles I need to clean.
It is very strong, which I love, as every other brush I have bought is so flimsy as to be useless. I really needed one that was strong like this, but fit a liter bottle. This one I can barely force into a 1/2 gallon and the metal shaft prevents the brush from touching the bottom of the bottle, thus it does not clean it.

Great tool for cleaning gallon jugs.
