If you have a hard to reach window, there are a few things you can do to clean it. First, use a plunger to suction onto the top of the window and pull. This will push any dirt and debris out of the way so you can clean it. Second, use a vacuum cleaner with the hose attachment to suck all of the dirt and debris out of the window. Finally, use a bucket or spray bottle filled with water to rinse the window.
