I've run across references to chlorine trifluoride quite a lot. It pops up fairly regularly on the Worldbuilding SE, and whatever idea people have with it is usually shot down very quickly - For obvious reasons.
One of the things that comes up in almost any web search about chlorine trifluoride is that it doesn't react with "candle wax" pretty much at all. (Example here)
Is this true? If it is, why? What is so special about candle wax that makes it immune to this substance that reacts extremely well with almost anything on, in, or around Earth?
(Worth noting: I'm not a chemist, so a basic overview would be appreciated in addition to any extensive scientific answer. Said extensive scientific answer is also appreciated because I'm sure there's others that would like the answer to this as well.)
