Deodorized Kerosene? Decades ago my wife came home with a Charcoal chimney and I though how stupid ! Instantly I found out the charcoal chimneys were a great product..
Kerosene doesn't light very easily though. I remember after Die Hard 2 came out there was a group of Bell Labs scientists who tried to recreate the lighting of a jet fuel stream in an empty section of their parking lot. They substituted ordinary hardware store kerosene which they figured was close enough. They couldn't do it. Tried tossing a lit Zippo into the stream and then kept on trying more and more stuff. I think they finally managed to light it with a blowtorch.
Don't smoke but I do have a few Zippo lighters. Their newer fluid is supposedly "synthetic" although that's kind of an overused word these days. Still - I've heard claims that it has less odor than the previous version, it burns cleaner, and for those keeping them in pockets it's not as irritating if it gets on skin.
Apparently Royal Oak bought the rights to what used to be Gulf Lite charcoal starter. I guess that was from back when Gulf Oil actually made it as a byproduct of oil refining. The only big competitor I remember back in the 70s was Wizard from Boyle-Midway, which was more a cleaning products company than anything else.
