This is the beer line cleaner that I've been using for quite a while. I used to use BLC but prefer the Clean Flo and it has done a good job.
Tonight I was cleaning a corny that had had some honey ale in it. The sediment at the bottom was being quite stubborn and as I was going to use the keg to push Clean Flo through the lines anyway, I decided to see what the Clean Flo would do to dissolve the sediment. I put in a half scoop and a quart of hot water and within a few seconds the bottom of the keg was shiny and clean. I'm going to try it on my carboy next batch I brew.
