I was using a hair brush in the bathroom underneath my carboy to tilt it as I racked it into the bottling bucket...forgot to move the bucket away first, and when I picked up the carboy, the brush fell right in. No infection, but wouldn't recommend as standard practice.
I missed this one Moonshae, this is exactly how my bottling bucket diptube got invented.....Only it wasn't a hairbrush it was one of those big BBQ lighters that I was using, until it fell in.
