Rob Benson on Instagram: "Denatured alcohol is ethanol treated with additives that make it stable and long lasting. Stove fuel for alcohol burners Reliable for camp stoves and emergency cooking Burns clean with minimal residue Comes in a ready to store container Useful for fire starting in bad weather Works as a degreaser for tools and gear (I would think... never tried it) Straight ethanol is not good for long term storage but denatured alcohol is different."
