just just acetone? it works the best anyways. 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!
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.
