Abstract: A blade cleaning device for cleaning fan blades includes a funnel, which has a top that is rectangularly shaped and circumferentially larger than a bottom thereof. A conduit, which is engaged to and extends from the bottom of the funnel, is engageable to a hose extending from a vacuum cleaner. A frame is engaged to and extends circumferentially around the top of the funnel. Opposed ends of the frame are dimensionally taller than its opposed sides, defining a recess into which of a cross-sectional portion of a blade can be inserted. The opposed ends are positioned proximate to opposed edges of the blade preventing rotation. A brush element engaged to the frame extends into the recess. The brush element dislodges debris from the blade as the frame is motivated longitudinally along the blade. The funnel directs the debris to the conduit for collection in the vacuum cleaner.
