I've never tried it but I've heard that ironing the card works. And that does make sense, because heating the laminate and the "sticky" that holds the layers of paper together would probably restore their holding properties. I spilled something on one of the new RWS decks and one or two of the cards came apart in the layers, but what I did was just put them back together with the damaged cards in the middle and now I can't tell which ones were damaged.
There was a thread sometime in the last month or so about someone (can't remember who though!) in New York whose OOP got liquid spilled on it in the subway. He detailed the process he eventually used to restore the cards and even posted pics of a couple of them. The results were night and day!
My entire life has been a Seinfeld episode, lol. What I'm going to do is use one of my old decks, totally destroyed, and use it as my guinea pig before totally destroying my new Revelations deck. aagghhhhh
Well, if you DO intend to iron them, put a towel over the card and do it on low heat. If you don't, the card just sort of bubbles and looks likea tortilla left in the oven too long.
