Pull the pantyhose over the opening for the vacuum's hose attachment and secure with the rubber band.
Run the hose over the back, outdoor-facing portion of the blinds. This will prevent dust from attaching itself to the window pane. Vacuum each slat of the blind individually for the best results.
Run the hose over the front, inward-facing portion of the blinds.
Mix the mild dish soap and warm water.
Clean stains and spots using the soap mixture and sponge. Do not use stain removers or solvents, as these could discolor the blinds.
