Indispensable for cleaning all kinds of carboys. 24" long and bent at a 90-degree angle to reach all corners of a carboy interior.
Do not use on plastic buckets or Better Bottle fermenters. For use with glass or stainless equipment only!
Very helpful cleaning the carboy. It doesn't do a very good job getting to the sides of the carboy but does well on the top and bottom.
While a bit unwieldly for 1 gallon carboys (they have a brush on NB specifically for 1 gallon carboys) it's a must-have for anyone with 5+ gallon carboys.
I've purchased five of these and they all work once or twice and fall apart shortly thereafter. I had to get a custom pressure washer tip designed and made so I wouldn't bother with these brushes ever again.
Changed the cleaning length and angle to increase the function. Twirling will clean the entire shoulder of a carboy. The brush still flattens out to clean the domed bottom. Pay attention to the shape of the bristles at the tip to avoid the wire contacting the carboy.
The tip of the brush gets the heaviest use but has the least bristles.
