Set up the storage area by cleaning, drying and airing the room. Make sure there are no insects or insect droppings.
Wear a pair of white cotton gloves. Dust the surface of the oil paintings carefully with a dry, clean, soft dust cloth.
Examine the frames of the paintings. Make sure the paintings are firmly attached to their frames.
Pad the paintings on both sides with polystyrene (sold in stores as Jablo) to protect the oil, frames and canvases from scratches, dust and moisture.
Move the oil paintings to the storage room. Place the framed paintings upright with the polystyrene in between the paintings. Store unframed oil paintings singly, flat on the floor between sheets of polystyrene.
