Best Answer

Ionic air purifiers. They charge or magnetize the particles and then they cling to everything. Remove a picture from the wall - is the ghosting around the outside? Remove a metal decorative piece - if the particles are magnetized the ghosting will be the opposite - it will be in the same design as the item.
