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. Similarly, a non-polar dye would require a non-polar solvent (e.g. toluene or a similar hydrocarbon). Check washing Check washing
Staple remover Staple remover A staple remover is a device that allows for the quick removal of a staple from a material without causing damage. Also known as a canassas, the best-known form of staple remover, designed for light-gauge staples, consists essentially of "a") two opposing, pivot-mounted pairs of thin, steep wedges and "b") a spring that returns the device to the open position after use. Although a simple metal wedge can be used for the same purpose, and although some staplers (especially small ones about long) feature such a wedge at their hinge end, use of the wedge tends to tear
