I have a lot of turnaround as far as beer and cornies. I honestly can’t imagine doing what others say they do on this forum to clean their cornies each and every time. If I don’t suspect any sort of infection at all from a previous batch, then I usually open up my corny, put very hot tap water in, close, shake around, open and pour back out. If this doesn’t get all the gunk out then I will scrub with a non-scratch pad. After one or both of these, I take 1 gallon of boiling water, pour it in, close the top, put it under serving pressure, shake the hell out of it and send some of this water out each dip tube. Then I just stack it in my clean area. When I am ready to refill, i dump out the now cool water and proceed with the fill. This method has not failed me yet and it takes almost no time. In a sense, it’s a bit like a mini autoclave, with the combination of the heat, moisture and pressure. From a microbiological POV, I am not sure that this amount of heat or pressure is prolonged enough to truly autoclave, but again, until it proves me otherwise I am sticking to it, cuz its just too damn easy. I am open to what others think of this method as well?
