Hi, Quite some years ago there was a Hint from Heloise regarding "liquid milk of magnesia freshens newsprint." I have not tried it. This may help. Dear Heloise: A while back, there was a hint in your column for preserving newspaper clippings. I used that recipe for years until they changed the formula, and now the milk of magnesia tablets do not dissolve in club soda. You are supposed to let it sit overnight to dissolve, but I waited three or four days, and they still would not dissolve. Answer: You are absolutely right. The original hint from my mother's column back in the 1960's said to use liquid milk of magnesia, not the tablets. After calling a manufacturer, we found that there are three different types of tablets today, and none of them will dissolve in club soda. The recipe for preserving newspaper clippings and keeping them from turning yellow does specify using liquid milk of magnesia. Mix 1 quart of club soda with 2 tablespoons of liquid milk of magnesia. A key step is to put the solution in the refrigerator for eight hours before using. Use a shallow pan that's large enough to hold the clippings. Put only one clipping in at a time and let it soak for an hour. Remove it carefully and place it between several layers of white paper towels (to remove moisture). Be sure to let it day on a clean, flat surface. That's all there is to the magic formula. P.S. Please note that today's newspapers are printed using different amounts of recycled paper, and your results might vary.
