A cloud of sand coming from the Sahara will sweep the sky this weekend. Partly linked to the heat wave which will hit the country on Friday and Saturday, with temperatures reaching summer levels.
Dust can be difficult to wash away and when it is hot, the sun can burn the grains of sand, which can end up becoming embedded in the paint. It is best to use a high pressure jet, like those offered at many car washes, to clean your car. If the sand itself is not aggressive for car bodies, it is better to protect your car or to wash it without waiting too long.
