I'll second the recommendation for Naptha. Also called VM&P Naptha (V arnish M akers and
P ainters). Not only is it less expensive, of all of the solvents available, it is the LEAST harmful, though I highly recommend using Nitrile gloves and either a respirator or a well ventilated space when using it.
Naptha also works well in dissolving ATG, though do not try it on inkjet prints because it will dissolve the ink.
