Materials You Will Need
rubbing alcohol (isopropyl alcohol)
shaving cream (if the alcohol doesn't remove the ink)
hairspray (if neither the alcohol nor shaving cream works)
non-flammable dry cleaning fluid (another option)
Ink Removal Instructions
Dab rubbing alcohol onto the ink.
Allow a couple of minutes for the alcohol to penetrate the surface and react with the ink.
Blot the ink stain using layers of white paper towels or a cloth that has been dampened in either alcohol or water.
If the alcohol is ineffective, try using foaming shaving cream.
If the shaving cream doesn't work, hairspray usually will remove ink, but it should only be used as a last resort because hairspray damages some surfaces and fabrics.
Non-flammable dry cleaning fluid may remove certain inks. If you use dry cleaning fluid to remove a stain, rinse the area with water afterwards.
