Wash your vinyl windows using mild detergent (if necessary) and a soft cloth. Do not wash the windows with a high pressure spray. The extreme pressure could crack or destroy the caulking around the window. For difficult to remove dirt and stains use the readily available household cleaners listed on the chart. Follow the manufacturer’s instructions on use of the cleaners. In some cases you may wish to use a mildly abrasive cleaner such as Soft Scrub, but the use of any abrasive material could scratch the surface of the glass and window frame. Do not use liquid grease remover, strong soaps and detergents containing organic solvents, nail polish remover, furniture polish, or cleaners containing chlorine bleach. These items could affect the surface appearance of the vinyl.
