Suggestions for saving cards

Hi all!

I recently was gifted some cards that were in someone's attic, and some of them had water damage and have kind of congealed into a clump. Trying to separate them causes a lot of tearing - to the point of total destruction.  Has anyone had success saving cards in this state? I am not expecting to get them to close to LP, but it sure would be nice to at least have them be readable.
