Check washing process of washing a check is relatively simple and can be accomplished with basic solvents. The actual solvent is largely irrelevant — more importantly, the polarity of the solvent must match the polarity of the dye in the ink. For example, an ink that is mostly made of a polar dye would require a polar solvent (e.g. acetone or isopropanol). Both nail polish remover (acetone) and rubbing alcohol (isopropanol) are able to pull most common inks away from paper in minutes.
