How do I clean my Duo Form Exterior skylight?

Wash the skylight with a mild soap or detergent (e.g., Joy^® Dishwashing Liquid) and lukewarm water using a clean sponge or a soft cloth. Rinse well with clean water. Dry thoroughly with a chamois or moist cellulose sponge to prevent water spots. Do not scrub or use brushes on skylights.
DO NOT use abrasive or highly alkaline cleaners on this skylight. NEVER scrape skylight with squeegees, razor blades or other sharp instruments. NEVER use benzene, gasoline, acetone or carbon tetrachloride on skylight. DO NOT clean skylight in hot sun or at elevated temperatures. DO-NOT use Butyl Cellosolve™ on the skylight.
PRO TIP: MINIMIZING HAIRLINE SCRATCHES Scratches and minor abrasions can be minimized by using a mild automobile polish. Four such products that tend to polish and fill scratches are Johnson^® Paste Wax, Novus^® Plastic Polish #1 and #2 (Novus Inc., Minneapolis, MN) Mirror Gaze^® plastic polish (M>G>M10-Mirror Bright Polish Co., Pasadena, CA), and Plexus^® (B.T.I. Chemical, Aguora, CA). It is suggested that a test be made on a small inconspicuous spot of the skylight with the product selected and that the polish manufacturer’s instructions be followed.
