What is the preferred cleaner for plastic surfaces such as windshields?

The preferred choice for cleaning plastic surfaces, such as windshields in aviation, is mild soap and water or a manufacturer-approved cleaner. This approach is recommended because it effectively removes dirt and debris without causing damage to the plastic.

Plastic surfaces are sensitive to harsh chemicals, which can cause cloudiness, scratches, or deterioration over time. Mild soap and water provide a gentle yet effective cleaning solution that maintains the integrity of the material. Manufacturer-approved cleaners are specifically formulated for use on plastic surfaces, ensuring compatibility and minimizing the risk of damage while also effectively cleaning.

Using acidic solutions or heavy-duty degreasers could harm the plastic by etching or stripping protective coatings, while bleach and water might lead to discoloration or surface degradation. Therefore, opting for a mild soap and water combination or a cleaner that the manufacturer recommends is the safest and most efficient method for cleaning plastic windshields and similar surfaces.
