Either degreases. White spirit is more toxic.

I would have thought white spirit would leave a residue ?

Other way around - white spirit leaves no residue or smell once it's
evaporated, but being much less volatile, that takes much longer,
and it stinks more until it's evaporated.
Your alcohol will have additives to make it toxic and to colour it,
and these leave residues. (Pure ethanol wouldn't, but you can't buy
that without paying lots of duty.)


When I was a haematology techician in the 70's we had 2 litre
'winchester' bottles of pure ethanol in the lab for diagnostic purposes,
presumably tax-free because I remember it was absurdly cheap for 2
litres of 100% alcohol.

Medical students were always trying to get pally with the female
technicians (not many female medical students in those days) to try and
get something to make their party drinks go with a bang.

One day Customs and excise paid us a visit and insisted that we kept
a register of the exact amounts removed for diagnostic purposes and
to *return* the excess back to the container.

Chief technician got quite agitated explaining why we would and could
not do this. Eventually it was escalated up to higher levels to make
them shove off.

Even normal hot weather (no aircon in those days) made it evaporate
pretty quickly, apart from the no-no of contaminating the bulk bottle.
