I wonder if this will still work 2 or more weeks after the sharpie has dried off. Great discovery!

Sounds like you just figured out how to remove sharpie from a modern book. Really interesting study… How long in the box do you think it actually took to lighten it enough to fade that much and could you localize the peroxide without spaying, like using a Q tip or something? Nice video!

Wonder what would happen with ink? In certain scenarios (ink on a white background for instance) might have some value?

interesting, and of course I 'm still not a fan of using peroxide on comics.
