Dehumidification-drying has been successfully employed in-situ for slightly damp materials where items are dried in place, without removing them from their shelves or from their boxes.
Though our experimental records were wet, not damp, we were anxious to see how well the dehumidification system already set up on-site could successfully dry wet items in situ. Would they eventually dry? How long would it take? Would mold grow under such dry ambient conditions?
