Printer Ink: Remove dried stains on smooth surfaces
Even old, long-dried ink stains can be easily removed from smooth, non-porous surfaces (plastic, melamine resin coatings, etc.):
Put a splash of scouring cream on a soft cloth, rub gently until the stain disappears. Then wipe with a clean, slightly damp cloth. Caution: The microparticles in the scouring cream can add to some surfaces. If you want to be on the safe side, try out the effect first in an inconspicuous place.
