I assume you are talking about Wite-Out (correction fluid for typed papers) picture”
I have never gotten it out chemically. (like with a solvent). The only way I have ever removed it is with a sharp blade, even a scalpel blade, gently rubbing on the surface/
Unfortunately, Wite-Out, Liquid Paper, and similar products, aren’t meant to come out. Some things don’t come out without doing even worse damage than the wite out.
