Among ball-point pens, those with black ink are often the most difficult to erase or remove. Typical ink erasers are two-sided erasers: one side has a sanding type of property that erases by removing the surface layer of the paper, the other side is usually a vinyl eraser that contains a chemical that acts on the ink to remove the ink. Some of these erasers will not work well with black ink. The chemical most commonly used to remove inks from paper and other materials is generally a group of solvents. When the ink is on a material other than paper, lift the stain using the liquid form of the solvent.
Select an ink eraser. Sand and scrape off the top layer of paper using the rough side of the eraser.
Rub the ink with the vinyl side of an ink eraser. The vinyl side has a solvent-type chemical that is designed to act on the ink to remove it from the paper. This solvent will work on some ink mixtures but not on all varieties, particularly gel pens.
Dip a cotton swab in a solvent such as: benzine, bleach, carbon tetrachloride, methyl ethyl ketone, acetone or clear correction fluid.
Rub the wet cotton swab across the black ink. Use a clean swab to pick up or absorb the solvent as it dissolves the ink. Test each chemical separately and do not allow the chemicals to mix together. Test the chemicals first on a similar piece of paper with the same type of ink rather than on the paper you want to clean.
