Clear visibility is vital for safe driving, and maintaining a clean windscreen is key to achieving this, especially during sunny conditions when glare can be problematic. The German car association ADAC emphasizes the importance of regularly cleaning both the exterior and interior of the windscreen and rear window to prevent the accumulation of dirt, pollen, and smears. These contaminants scatter light, increasing glare, particularly during low sun hours in the morning and evening. To effectively clean your windscreen, use a glass cleaner along with a microfibre cloth. For tougher stains like tar or fly droppings, opt for specialized cleaning products. When cleaning the inside of side windows, slightly lower the windows to access hidden areas. It’s advisable to clean the windows in the shade to avoid streaks, and using different cleaning directions for inside and outside can help identify streaks more easily. Additionally, after a car wash that includes a wax treatment, it is important to remove any wax residue from the windscreen and wipers to ensure they function properly without leaving streaks.
