Is all naptha ok? Reading a bit it seems to be what most people use. However, reading a little more, some believe that if it leaves a resudue not to use it. Is this true? Have not checked if the stuff I got does leave a residue, but is this a step i would not want to skip?
DO NOT USE IT if it leaves a residue, this will make you very sick. I recommend leaving it out overnight instead of a few hours. I once did the same test and I also thought it was a residue, turned out it was just a spot where the naphtha had been. If you skip the naphtha step there will be no point in doing the extraction at all.
