I would think -- and this has been reinforced by people much more knowledgeable than myself -- bleach or some sort of caustic agent. I posted the contents of an email I had received early in the thread to this effect. Maybe there are newer and better methods, but I am just really skeptical that water alone could bring about that change. I mean on the SGC 50 detailed scan I posted, look at the contrast between the protected areas on the right side and the rest of the card.

If you search this forum, there are many threads about successful soaking with just water...and cards that were a lot worse than the Di Maggio. Here's one...

Check out post #10. Not only does the paper and glue come off, the glue stains come out as well. Watch the video. You'll notice that after the paper is removed, there are still glue stains on the card. I'm guessing he soaked it long enough to remove the glue stains as well.

To my eye the issue with the DiMaggio was toning, not staining, and my understanding which could be wrong is that water alone will not remove extensive toning.

Maybe it is toning? There are ways to remove toning without even getting the card wet. Edited the details per Justin's request below, but he knows too.

Done. I just wanted to show there are ways to remove/reduce toning where no chemicals touch the card at all...which I'm of the opinion that it's not considered altering given that it doesn't change the card whatsoever.

Understood, I just wish to respect all opinions.
