***WARNING!!! Burning Isopropyl Alcohol / Rubbing Alcohol Indoors Is a HEALTH HAZARD!!!
It took me about a month to find-out that Isopropyl Alcohol / Rubbing Alcohol does not "burn clean" and leaves soot EVERYWHERE!!! I wont even use "alcohol" for fuel or heating indoors or outdoors!!! Now, I wont even burn a candle indoors!!!
