A vertical blind cleaning tool includes an elongate handle having a first end and a second end. A cavity is positioned in the handle. An outlet extends through the first end and into the cavity. A prong attachment is removably attached to the first end and includes a tubular member with a prong portion and a coupling portion. The coupling portion has a free end removably insertable into the first end of the handle. A receiving conduit extends through the prong attachment and may be fluidly coupled to the outlet of the handle. A plurality of openings extends through an inside surface and into the receiving conduit. An adsorptive membrane has a shape and size generally equal to the inside surface. The membrane is frictionally coupled to the prong portion. Fluid may flow from the cavity to the membrane and the membrane moved along either side of a vertical blind.
