I have read with great interest the various threads of people removing "gunk" on their cards with distilled water. I don't have many cards with "gunk" on them, but let me say my horror stories with them. I have tried to remove gunk on cards with simple water and nylon rubbing with disastrous results. Ironically, both are these cards are from 1933. Maybe I should have left well enough alone. If I had allowed the gunk to stay, would these cards have been no better than 1's??
