How to Remove Spilled Ink From Paper
- 1). Mix a solution of one part hydrochloric acid and six parts water. Mix together with a paint stirrer and pour into a large, shallow pan. A metal pan is best, because the acid can eat into ceramic or plastic containers. You can also use a glass container for holding the acid.
- 2). Test the solution on a scrap piece of paper before trying to remove the ink from any important piece of paper. Draw on a piece of paper that has similar properties as the paper that you are trying to restore. Place inside the container and allow the acid to eat away at the paper. A few seconds later remove the paper. Note any adverse effects that the acid had on the paper. If necessary, reduce the concentration of the acid inside the container.
- 3). Place the sheet of paper inside the acid solution. If you do not want to remove all of the ink from the paper, then do not submerge the entire sheet of paper. Instead, dip a sponge into the solution and dab over the ink that you want to remove. Do not touch the acid solution with your bare hands. Always wear rubber gloves and goggles to protect yourself.
- 4). Remove the paper from the acid when you notice the ink has lifted. If you are sponging the ink away, stop sponging when the ink has been removed. Place the piece of paper inside another large, flat container.
- 5). Rinse the paper immediately with cool water to stop the acid from eating the paper away completely. If you have submerged the entire sheet of paper in the acid, then you can do the same with the water. Handle the paper carefully at this point; it is likely that the paper is very delicate and will tear easily. If you sponged the paper with acid, then you can also sponge it with rinse water. Allow the paper to dry on a flat surface.
