"Petroleum distillates" come in many diferent
volatilities. The more volatile ones, like naphtha
and paint thinner, do not harm lacquer or acrylic
finishes. (I would hesitate to recommend their use on
violin varnish or traditional spar varnish or "french
polish" finishes.) These liquids will evaporate over
a few days, and not remain in the wood. They are very
useful in removing old stickum from masking or duct
tape, built up wax, etc.
Lubricating oils are also petroleum distillates, with
much lower vapor pressure. They evaporate slowly or
not at all. When used for a tuning machine lubricant
or fingerboard oil, they can seep into the wood and
loosen the adhesion of the finish to the wood. Also,
they would prevent glue adhesion should the wood ever
need to be repaired. Naphtha can be used to remove
oil from wood with variable success. To oil a
fretboard, I would suggest an oil that hardens in the
wood in a day or so, and hence will not migrate very
far in the wood. Watco danish oil, minwax natural
color oil, boiled linseed oil, etc. are good.
I have no experience with sesame and walnut oils.
Lemon oil will stay liquid for a long time, but will
also slowly evaporate, and need to be reapplied every
year or two.
