This does remind me that WD-40 appears to me likely to work, when it
remains suitable given concerns of flammability and ability to mar some
surfaces.

Keep in mind that WD-40 is a mixture of various ingredients that take
various amounts of time to evaporate, possibly including eternity (though
my experience using WD-40 on bicycle chains indicates otherwise).
