Nail Polish remover=BAD. DO NOT USE IT. Acetone in and of itself is a solvent that wouldn't harm your cpu die or packaging, however, nail polish remover is not straight acetone. It often contains not only fragrances and dyes, but many varieties contain a form of dissolved GELATIN. Meaning when the Nail Polish remover evaporates, you're left with that crud on your processor dye and/or HSF. The best and safest thing to use is Isopropyl alcohol. The stronger the better. It doesn't have to be 100% but make sure it isn't mixed with anything besides water on the ingredients label.
