Has anyone attempted to remove dried rubber band from a card before?

Nice! Looks good. Improving it further would likely be risky. You could soften the hardened rubber by using isopropyl alcohol, which would turn it into a slime that you could probably wipe off, but that would also cause the inks to bleed if left on for too long. Diluting it might work, but again, it's still high risk.

I wouldn't use Bestine solvent on it though. Some people claim it's just pure heptane, but that's very much not true. It's actually only 25% heptane. It does not evaporate cleanly like other solvents and will leave an oily residue behind. I can detect if a card was soaked in Bestine, so the grading companies *should* be able to detect that as well.
