gvape, the vapor tubes will fit all of the log vapes. The cleaning of these is sort of a two step process. The stem tip comes out for easy cleaning. That can be soaked in iso or Everclear (or 151) for cleaning. The tube itself should be cleaned, if necessary, with a pipe cleaner (which Ed supplies) dipped in iso or whatever you are using. The tube should NOT be submerged. If there is buildup in the metal part where the stem tip is inserted, you can use a Qtip dipped in your solution. I haven't found it necessary to clean any of the tubes I have yet, and I have had a couple of them for quite a while. I just take out the stem tips occasionally and give them a good soak. And congrats on getting your thread Ed!
