Just for the record, jet fuel is LESS flamable than gasoline. Higher cetane=higher resistence to burning. However it's a real good idea not to use jet fuel(diesel very similar) for cleaning anything...especially w/ an open flame near by. Now biodiesel, I may have to try. Non flamable, nontoxic and biodegradable. Hmm, I might still have some BioD in a fuel can, but I think I'll stick w/ vodka. Biodiesel IS however great at cleaning a really messed up toilet. lol
