Dust-Off is a brand of dust cleaner (refrigerant-based propellant cleaner, which is not compressed air and incorrectly called 'canned air') containing difluoroethane; it is used to remove particulates and dust from computers and electronic equipment. Dust-Off products are used to remove dust, debris, fingerprints, and smudges from hard to reach areas of keyboards, screens, and other components of electronic equipment. The Dust-Off brand also encompasses a line of electronics and home office cleaning supplies, including LCD/Plasma screen sprays, microfiber cleaning cloths, and the Dust-Off Screen Shammy. Dust-Off is manufactured by Falcon Safety Products. The compressed gas duster product has also gained attention as it has been abused as an inhalant by teenagers, as seen in the movie Thirteen. A warning email has been circulated by Jeff Williams, a police officer in Cleveland, whose son, Kyle, died after inhaling Dust-Off in Painesville Township, Ohio.
