I'm not sure what the formulation was in the

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!
Wikpedia references EU Regulation 162/2013, which gives the various recipes
across the EU:

Taking a random sample from a few different countries, the basic recipe seems
to be 1% mixed crud to make it unpalatable, up to 10% methanol, and the rest
ethanol. The ethanol and methanol will evaporate readily enough, but I'd be
somewhat concerned about residue left from non-volatile components of the 1%.
It's not like isopropanol is terribly expensive or difficult to get hold of. I
can order ten litres of it from Amazon ?28.66 with free delivery. If anything,
it seems to be slightly cheaper than meths.
