Before you get started, sweep dirt from the window frame with a brush or vacuum it up with your machine’s dusting attachment. This will prevent dirt from turning into a muddy mess when mixed with a cleaner. If your window screen looks especially grimy, pop it out and wash with hot, sudsy water and a soft brush, then rinse and let dry before putting it back.
For quickly dusting shades and blinds, Forte recommends going over both sides with a microfiber duster or opening the slats and going over each one with a damp cloth and followed by a dry one.
