Invisible Ink, How can I make the combination visible again?

Invisible Ink, How can I make the combination visible again?

I received and very nice SAFE about a week ago.

I have the key but the combination to the lock was printed on a piece of standard paper with a black felt tip marker. The paper was in a plastic bag but the paper got wet and the ink with the combination vanished.

I can just barely see that there is something there if there is fluorescent light hitting the paper from both sides.

I figure I have one chance to retrieve the combination.

Any of you super chemist sleuths know how to bring back the writing?

The previous owner has moved and is not available.

    Try lemon juice. That or visit your local police department detective. They like solving funny cases such as this one.
