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 polish and carbon disulfide may have adverse effects on reproductive health. These effects may including birth defects, low birth weight, miscarriage, and preterm birth. Nail polish formulations may include ingredients that are toxic or affect other health problems. One controversial family of ingredient are phthalates, which are implicated as endocrine disruptors and linked to problems in the endocrine system and increased risk of diabetes. Manufacturers have been pressured by consumer groups to reduce or to eliminate potentially-toxic ingredients, and in September 2006, several companies agreed to phase out dibutyl phthalates. There are no universal consumer safety standards for nail polish, however,
