Denatured alcohol which is ethyl alcohol can be denatured in dozens of different ways. It used to have benzine in it and has to have some type of chemical that will be a deterrent to drinking it. It is moonshine. If it is hydrogonized, which is the cheapest way to go it will have methanol and Pyridine.Pyridine is used as a polar, basic, low-reactive solvent. I’ve repaired guidance systems and nukes themselves and we used nothing but Denatured Alcohol. '''Isopropyl alcohol even at 99%; the''' water would need to be deionized and demineralized, And that would be expensive. Just my $.02.
