Ink stains can usually be dissolved with rubbing alcohol or hydrogen peroxide.
The best way to remove an ink stain is to dissolve it. Rubbing alcohol and hydrogen peroxide can dissolve many types of inks from most surfaces including paper, fabrics, wood, carpets, tiles and counter tops. While these will successfully dissolve most of the ink, occasionally some of the stain will remain and may become permanent.
Dip a cotton swab or the edge of a cloth in either rubbing alcohol or hydrogen peroxide.
Rub the cotton swab or cloth into the ink spot or stain. Allow the rubbing alcohol or hydrogen peroxide to sit on the ink for 5 minutes.
Wet a clean cloth with cool water. Wipe the ink stain or spot. Repeat the process until the ink fully dissolves.
