For safety reasons, it is essential to clean the windscreen, headlights and mirrors regularly. They are subject to the weather, splashes from other vehicles, bird droppings, insect impacts and other dirt. On the road, you need to have optimum visibility, day and night, whatever the weather. A clean windscreen and mirrors allow you to see other road users properly, while properly cleaned headlights ensure that you are seen by other road users. A dirty or foggy windscreen also causes glare when you pass another vehicle. A very real risk for an accident!
