Wax is clean with no impurities. Other brands melt at higher temps because they contain other crap, not 100% pure wax. I melt the wax and add an equal amount of charcoal lighting fluid. Then dip facial pads into the mixture. Lay them on wax paper and have about 200 fire starters ready for cold nights! Store the starters in a plastic bag and tear the pad about halfway to expose cotton fibers that get the starter going!
