Rigged this up just the other day while getting ready to clean enough bottles for my brew. Fairly new to the forum, so don't really know if it's been posted or not! BUT it works like a charm!!!
I am not sure what you are showing off. The picture is too small to really make out what it is that you want us to see.
I think he's got a bottle brush attached to a drill...
Yea sorry with the small picture...but it is a Bottle brush attached to a drill.
Yup! That's how I do it. Works great.
