While we do not do it every day, the natural history specimens on display the Museum need regular cleaning, particularly those specimens that are not housed inside of museum display cases. Specimens, like the polar bear, accumulate dust just like other surfaces in the museum.
To clean them we use vacuum cleaners with HEPA filters and variable suction control, fine mesh netting, clean brushes, gloves, ladders, extension cords, and time. The netting is placed over the nozzle of the vacuum cleaner so that large particles cannot be accidentally “sucked” into the vacuum.
The suction control is adjusted so that just enough suction is applied to pull in dirt and dust particles from the air, but not to harm the specimens. The brushes are used to gently pull dirt away from the surface of the specimen with the vacuum nozzle head held just above to collect the now loose particles of dust and dirt. This kind of cleaning is performed on a regular schedule for specimens on permanent display or as needed when additional specimens are installed in new exhibits, like the bison mount in Food: The Nature of Eating.
