Large amounts of dust collected on astronauts' space suits during excursions to the lunar surface. Following the Apollo 12 mission, Astronaut Alan Bean noted that they had lacked a means to remove the dust from their suits prior to entering the Lunar Module after returning from an EVA. Subsequent missions were equipped with large brushes, which were used extensively by the astronauts greatly improving the cleanliness of the Lunar Module cabin.
This brush was used during training and NASA transferred it to the Museum in 1979.
