"Denatured Alcohol" is ethanol with any of a number of added items to make it non-drinkable. "Fully denatured alcohol" contains methanol and a few other things so it can't be purified into potable ethanol in any practical way.

Ethanol and Isopropanol are chemical close cousins and, as cleaners, work equally well. Just don't use isopropanol in your martini.
