Spray Down Windows with a Hose With the hose, spray the windows and any surrounding areas to remove dirt and debris from the surface. Spraying down your outdoor windows with an adjustable hose allows you to turn up the pressure and get the dirt and grime out of difficult-to-reach areas in and around them.

To play it safe, use an ammonia-free window-cleaning solution. Or fill a large bucket with water and several generous squirts of liquid dish detergent and vinegar. Dip the sponge or microfiber head in the water and use it to scrub the windows, periodically rinsing and squeezing out the water.
