Saving newspaper clippings for posterity can be a problem as there is a tendency for newsprint to turn yellow. There is a "bleaching' method which should prevent your articles from turning yellow and allow them to survive for up to 50 years. This simple homemade bath helps counteract the acid in newsprint that causes the yellowing/aging.
To be safe obtain more than one copy of your clipping as insurance against your first attempt suffering a mishap.
Mix and refrigerate [for 8 hours] 2 tablespoons of milk of magnesia with 1 quart of club soda.
Pour the mixture in a shallow pan and let one clipping set for an hour, make sure the pan can accommodate the largest clipping. Remove the clipping and remove the excess moisture by laying the clipping between several layers of paper towels and then let dry on a flat clean surface.
When complete store in an "archival-quality" album.
