I know that I probably should, but does everybody out there always dissconnect the in and out posts from they're corny's before rekegging?
I disassemble, clean, and sanitize everything...every time.
Why risk a great tasting brew due to sloppy sanitation?
don't forget to apply some "food product safe" lubricant to all of those o-rings and seals each time too. You'll be much happier in the long run
I only disassemble everything once in every four brews. For the brews where I don't disassemble I give the keg a good clean with washing-up liquid and a cloth (I can get my whole arm in, just) and fill with a Videne mix sanitiser (similar'ish to StarSan) and pump this out through the out-post and beer tap. I've yet to have one go bad on me.
I have to agree with this....it's not necessary to disassemble each time but should be done every couple of brews. The kegs are kept cold and the chance of any contamination from dirty kegs is low. The sugar in your beer should low and the alcohol in your beer should help with sanitation. I know it only takes a few minutes but that’s a few minutes you could use on recipe formulation and sanitation in other areas that are more important.
