Clean Window Insect Screens: Six Steps with Soft Brush and Mild Soap
Identify your screen type and safely vacuum, wash if permitted, rinse and dry it.
Pella advises a soft upholstery-brush vacuum or a mild soap-and-water wash for many conventional fiberglass screens. Andersen recommends a soft brush, mild soapy water and thorough rinsing for its screen mesh and frame. Follow your particular model's instructions. Never lean out or try to remove a screen from an unsafe height; screens do not prevent children or pets from falling.
