Recently our mother was sent a box of papers, books, and photos after a relative's death. While she was pleasantly surprised by what the box held, it's all been sitting on the patio table because she's not sure what to do about the very strong musty smell.
We just read that if you place musty books in a plastic bag with baking soda, the miracle crystals will absorb the odors after a few weeks. We're planning to try it with the box of memorabilia (although we're not sure about the photos), and will report on the results of the experiment.
