Prints, maps, framed items, and other artwork needs to be handled with great care, as careless vacuuming or dusting can damage fragile surfaces. A useful mold removal method is to place a piece of fiberglass insect screening over the piece, then vacuum through the screen to remove as much of the inactive mold as possible. If you are working outdoors and wearing a respirator, a soft brush may be employed to gently remove the mold. Take care not to grind the spores into the medium or the paper fibers. If framed materials show signs of mold on the inside of the frame enclosure, the artifact should be unframed, treated, and reframed using new matting and a frame that has been thoroughly cleaned and dried.
