ABSTRACT:
The present invention involves a solvent vapor transfer device for holding an absorbent pad, which receives and disperses solvent vapors over a lacquer-based residue on a textile. A solvent is poured or dripped into an absorbent pad portion of the vapor transfer box, from which solvent vapors are released. The solvent vapors pass through the vapor transfer box and concentrate in a vapor chamber over the lacquer-based residue and textile. As the solvent vapors come into continuous contact with the lacquer-based residue, the residue begins to dissolve and soften. Upon sufficient dissolution, minute quantities of the liquid solvent may be applied directly to the partially dissolved residue and quickly suctioned into an extraction vacuum. This process may be repeated as necessary to achieve complete removal of the residue.
