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. Some customers buy Dust-Off just to clean dust and debris from hard to reach areas. Dust-Off is manufactured by
Falcon Safety Products.
The 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.
Falcon has now added a bitterant to the product to deter inhalation, probably in response to the above and other cases.
