A window maintenance apparatus for a tilt-in sash includes a base leg for extending generally upwards from a floor towards a window. The base leg includes a first foot for resting on the floor. A hinged leg is joined to the base leg proximate an end of the base leg for extending generally downwards towards the floor. The hinged leg includes a second foot for resting on the floor. An extension tube extends upwardly from the base leg where a length of the extension tube above the base leg is adjustable. A locking mechanism locks the extension tube at an adjusted length above the base leg. A first sash support is rotatably joined at a first position on the extension tube for rotating about the extension tube from a first position to a second position for supporting the tilt-in sash in a generally horizontal position.
