From a 'conservation' point of view, the method for removing waxes is to use white spirit (turps substitute) applied with swabs (cotton buds?).

Check the effect of the W/S on an unobtrusive area. If there is no effect on the lacquer, go ahead with neat W/S.
If there is an effect on the lacquer, check the effect of methylated spirits on the finish, there should be no effect (polar and non-polar solvents)therefore mix the W/S & meths until the mixture only just dissolves the wax and remove with swabs (see above).
