The sand covering the car is likely due to a natural phenomenon where sand from the Sahara Desert is carried by strong winds and atmospheric currents over long distances, reaching places such as the UK or other regions. When the sand-laden air meets rain, the sand particles get caught in the raindrops and fall onto surfaces like cars. After the water evaporates, a visible layer of sand or dust remains on the car's exterior. This sand is different from ordinary beach sand; it is finer, abrasive, and often reddish due to iron oxide content. The presence of such sand can gradually degrade the car's protective clear coat and paint if not removed properly. This occurs during rare weather patterns when desert storms in North Africa coincide with winds that carry the sand far away. It can settle on vehicles, windows, and other surfaces, posing risks to the paintwork and visibility. It is important to remove this sand carefully using proper washing techniques to avoid scratching the car's paint. This phenomenon has been noted to happen occasionally in various parts of Europe, causing a reddish dust layer sometimes called "blood rain" on vehicles and outdoor objects.
