Perhaps mineral spirits - sometimes called Varsol if I am not mistaken -
will do the job.

Is there a problem with coating the parts in wax even if they are still
coated in some residual oil? I expect the reason for the paraffin was to
waterproof the parts and as paraffin is just another form of oil would
it now work just fine all be it somewhat discoloured if the oil residue
dissolves into it? It just won't look as nice...

the amount of oil paraffin wax can hold is small.
