Smells nice too :-)

The problem will be finding someone willing to sell it apart from on the
internet. I have tried to buy isopropyl alcohol recently from 2 pharmacies
(for cleaning VHS tape recorder heads) but they told me that they are not
allowed to stock it or sell it.

You can buy meths almost anywhere - try an outdoor-type store; it's
widely used for such as Trangia stoves.
