Final answer:
Aircraft windows and windshields are cleaned using specialized glass cleaners that typically contain isopropyl alcohol, an alkaline detergent, and sometimes a mild abrasive. They are applied with a soft cloth or sprayed directly and then wiped clean for a streak-free finish. Protective equipment should be worn as necessary during cleaning.
Step-by-step explanation:
Cleaning Aircraft Windows and Windshields
To clean transparent plastic windshields and windows of an aircraft, specialized glass cleaners are used. These cleaners are composed of organic, water-miscible solvents such as isopropyl alcohol, an alkaline detergent, and may include a mild abrasive for a streak-free shine. They are often available as sprays or liquids and can be applied with a soft cloth or directly sprayed onto surfaces.
For optimal cleaning, glass cleaner is rubbed onto the surface with a soft, lint-free duster or glass cloth, and sometimes soft water is added with methylated spirit or vinegar to enhance the cleaning effect. In addition to these cleaners, there are special purpose cleaners designed for repeated use on specific surfaces, even on delicate optical components. It is recommended to use a new wet cloth for cleaning optical components to prevent scratching from debris caught in previously used cloths.
Moreover, dishwashing liquid, as an active ingredient in products like Pling, can be used as a general purpose cleaner on various surfaces, including plastic, and can even be used for applications beyond dishware, such as detecting leaks in pressurized equipment. It's crucial to use caution while cleaning, employing protective equipment like gloves and goggles when necessary, especially when dealing with broken glass.
