I purchased an estate Comoy's Tradition Canadian a few months ago. It was in good condition when I received it but I did a series of salt and alcohol treatments and retorts anyway to clean the bowl and shank of any ghosting from previous owner. The stem had a little oxidation so I followed advice and did the oxyclean soak followed by Magic Erasers followed by micro-mesh pads to make it look new again. My problem is, no matter what I do, I still can't get the offensive smell out of the vulcanite stem. I've soaked it in alcohol overnight, vinegar overnight. I've run more pipe cleaners soaked in both than I can count through it. It has the great 3 piece C in the stem so I don't want to look for a replacement. There has got to be a way to clean this. I know I have asked this question before but does anyone have a trick that I haven't tried?
