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
Nail buffing alternative to chemical nail polish. Nail buffing Nail buffing is the act of polishing the nail using buffers of successively finer grit in order to make nails look more consistent and shiny. A paste is used to fill ridges on nail surfaces. Traditionally, a buffing cream and chamois skin have been used. Modern instruments are much more efficient and are similar in appearance to a large rubber eraser, with different sides for different levels of coarseness. As buffing is gentle surface abrasion, it should not be performed too strongly or too often or thinning of the nail may result. In
