I have a book log (with fiil-in-the-blank spaces) that I keep track of what I read in. I try my best to keep it extremely neat, but I put the wrong information on a blank. How can I remove the ink (gel) without damaging the ink printed on the page? (There are lines to indicate where the answer should go.) I am using a Pilot G-2 07 pen.
If liquid paper is not an option, you can try the solution which I used when I was a child in school. Use a classic shaving razor, and carefully scrap away the ink. With enough care and patience, you can get the job done.
WARNING: if the ink penetrated the paper (instead of just sitting as a layer on the top of the paper), then the razor method will most likely end up creating a hole in the paper, before removing the ink.
