Hello Adrienne, Typically, conservators do not recommend deacidification. All items must be assessed individually, and I have never endorsed their routine use in any institution-certainly not for artwork. It's important to remember that deacidification spray is preventative, not restorative, and it only provides a superficial level of treatment. The only material I might even consider using it on broadly is newer newsprint, and even then, I have reservations. The most effective preventive measures remain proper storage conditions and appropriate housing materials. If an item is in good condition and encapsulated within a stable environment, it will remain safe. However, there are alternative options, such as encapsulating with buffered paper, leaving the encapsulation open enough to allow air exchange, storing items in cold storage, or limiting light exposure. Buffered interleaving papers, boards, and other materials can also be beneficial. There is extensive literature and research available on deacidification, and I encourage reviewing it further. A few references are listed below (though not comprehensive), and much additional research is published in Europe.
