When cleaning the canopy and windscreen, in which direction should you wipe?

Wiping the canopy and windscreen in a fore and aft direction is the correct method because it helps minimize the potential for scratches on the surface. This technique also allows for better visibility as it follows the natural flow of water away from the edges, preventing water from pooling and ensuring that all debris is effectively removed from the centerline of the canopy. The fore and aft motion helps maintain a uniform cleaning approach without introducing additional streaks that other methods, such as circular or diagonal motions, may cause.

Additionally, when applying cleaning solutions or wiping, it's crucial to use a clean, soft cloth to avoid damaging the surface. Scratches or imperfections can severely impair visibility during flight, making the proper cleaning method essential for both safety and maintenance of the aircraft.
