Once the tracks have formed this means that carbon has formed as well. 
Melting and re-distributing the carbon is a bad idea especially in a
transformer that is not really designed for Tesla duty service -- marginal
at best.  Best to remove ALL of the tar and set the xmfr in a plastic
tupperware dish and fill with xmfr or mineral oil (health food store). 
This will provide superior insulation with the tar/carbon problems which
will continue to plague you until you remove the source of the plague --
the carbon that forms.  You can also carefully clean up the core/coil
assembly before immersion with kerosine -- no flames nearby please -- and
then give a final rubdown with denatured alcohol.  A standard oven will
provide all the heat required for tar removal -- heat it slowly and for a
longer period of time as opposed to trying to get it all out in 20 minutes.
