A vent wash cover for covering an aircraft vent with a plurality of slots. The vent wash cover includes a main body, fingers, a threaded aperture, and a hollow conic section. The main body has a first end and a second end. The fingers are disposed on the first end and correspond in size and placement to the plurality of slots such that a seal is created between the fingers and plurality of slots. The threaded aperture is disposed on the second end, and corresponds to threads of a standard thread extension pole. The hollow conic section extends outward from the threaded aperture such that the threads of the standard thread extension pole can be properly aligned from a distance for insertion into the threaded aperture.
