Cleaning window screens is an important step in buttoning up your house for the winter. Window screens  that have been exposed to the elements all summer long require special care and attention to extend their service, and here are a few tips to make the task easier.
First, remove the windows screens from the window frames. Place the window screens on a flat surface (such as the driveway) and use a mild soap, water and a soft bristle brush to remove dirt and grime. Clean both sides of the window screen and around the interior and exterior of the frame. Rinse off the window screens with lukewarm water, and allow the screen to dry completely before replacing in the window.

Next, never use a pressure washer to clean window screens or windows because the force of the water can damage the units. Also, use extreme care when cleaning aluminum mesh, since it can be dented or creased if too much pressure is placed on the screen.
Finally, while most window screens may remain in the windows year-round, some homeowners prefer to store screens during winter months, which lessens the need for spring cleaning. If you choose to remove your window screens, make certain to store them either in an upright or flat position. Covering them with plastic or a sheet will keep windows screens clean while in storage. Finally, make sure nothing sits on top of (or leans against) the window screens to eliminate the chance of frames being bent or holes being poked in the screens.
