Hi i was curious if any one has, and can tell me how to clean a propane tank to use it as a main chamber for a bbq smoker. I am a welder and fabricator at heart and getting into smoking more and more over the last ten years, but this is above my ability as far as knowing what the nasty garlic smell from a propane tank would do to your meat. I have heard of people doing it but what they did is unknown. I have a very large 24" by 48" tank that was on my property when i moved here. Any help would be appreciated.
