What is recommended for cleaning transparent plastic windshields and windows?

• A. Harsh solvents like acetone.
• B. Bleach solution.
• C. Metal polish.
• D. Mild soap and plenty of clean water.

Answer: (D)

Clean plastic windshields and windows with a mild soap solution and plenty of clean water. Plastics such as polycarbonate or acrylic can be damaged by strong chemicals, so gentle cleaning is essential to avoid hazing, cracking, or clouding. Harsh solvents like acetone can dissolve or craze the plastic, bleach can degrade the surface and discolor, and metal polish is abrasive and not intended for plastics. Using a soft cloth with a mild soap solution and thorough rinsing removes dirt without harming the surface, and drying with a soft, lint-free towel helps prevent water spots and scratches. If stubborn grime appears, a cleaner specifically formulated for plastics can be used, but always avoid abrasive pads.
