When pitch, varnish or oil-paint stains have become dry, they should be softened with a little butter or lard, before using turpentine and soap. In these cases, a simple way is to soak the part in spirits of turpentine and when softened to wash it off with the same fluid. Burning-fluid combines the solvent powers of both alcohol and turpentine. Benzine is also good. Chloroform will also remove paint from a garment when almost everything else fails. The fats, resins and unctuous oils are dissolved by essential oils, as oil of turpentine. Common spirits of turpentine, however requires to be purified by re-distillation, or it will leave a resinous stain upon the spot where it is used.
