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
Water marble nail and are added to a cup of clean water. The drops will create a circle on the water surface. The next color is added on top of the circle created by the previous drop. The resulting pattern is ready for application to the nail, but it can still be modified with a stick or toothpick to create different shapes. The nail is dipped into the pattern on the water and kept under water as a Q-tip is used to "grab" the remaining polish.
