I'm not sure what the formulation was in the past but denatured alcohol
nowadays is just ethanol with maybe 5-10% methanol added. You definitely
shouldn't be drinking it (in vivo, methanol is metabolized to formaldehyde
via oxidative reduction - formaldehyde attacks the optic nerve - which is
why drinking wood methanol makes you go blind) but other than that, I
wouldn't say it's particularly more harmful to you, boards or components
than isopropanol is. You wouldn't want to drink that, either!
Best,
Sean
