acid-free storage

Acid-free storage refers to using materials that don't contain acids, which can cause paper and photographs to deteriorate, discolor, or become brittle over time. These materials have a neutral or alkaline pH, effectively slowing down chemical reactions that lead to decay. Using acid-free folders, boxes, or sleeves helps preserve the integrity and longevity of valuable or delicate items like documents, photographs, and artwork, ensuring they remain in good condition for future generations. This practice is essential for archival preservation and responsible handling of historical or sentimental possessions.
