I know this subject has been discussed many times before, but I have a very specific question.
My siphoning tubes retain odor. I clean and rinse them out immediately after use. I let the tube I currently have sit in boiling hot water, hoping that some of the smell would come out: it didn't. How can I clean my siphoning tubes to remove the smell? Should I let them sit in iodophor or something like that for a few days? I personally don't mind the smell, I'm just concerned that it will affect the next beer I do (i.e. a Pilsner following a Porter).
Also, how long does everyone use their siphoning tubes before "retiring" them?
