Interesting. I don't think I've ever seen a bottle of "rubbing
alcohol" that was anything but isopropanol-and-water. But I'm more
Canadian than US.
Many are possible in the local apothecary (aka drug store in
ISO70% + water
ISO91% + water
Ethanol (denatured)+ water
Then there are products with oil of wintergreen (green color) and other
and are identified on label.

precisely, with _different_ concern for purity. For rubbing
alcohol you want to avoid biologically active contaminants, but
dissolved solids per se don't matter. Here, you care about dissolved
solids but don't much care about things that might be biologically
active, as long as they evaporate without residue.
Generally there are no solids in
the first three and are safe for
is the materials are not affected by the alcohol in use.
Which leads me to tentatively suggest gasoline (West
Pondian) / petrol
(East Pondian), since it seems to me that will go to some lengths to
avoid fouling engines with residues. And it's available pretty much
universally, and relatively cheaply.
NO! Highly flammable and contains a laundry
list of things. Good
enough for cleaning
an engine of oil (with great care). Oddly Kerosene (aka paraffin) can
be had as (K1 crystal)
highly refined. Again it can acquire impurities from the source but can
also be purchased
in small containers for camp stoves and lamps.
Or am I wrong about it not leaving even trace
There is what was called "white gas" that was pure petrol
These days if you see it its for camp stoves and lights and not cheap.
Of course, anyone with distillation equipment could
distil any of these
to get something with less residue. But not everyone has chem-lab
Or the temperature controls to not render unsafe(highly flammable)
