Washing the vehicle by hand
Observe the legal requirements, for example in many countries washing by hand is only allowed at specially designated wash bays.
Wash the vehicle with lukewarm water and a soft car sponge. When doing so, do not expose the vehicle to direct sunlight.
Use a mild cleaning agent, e.g. a Mercedes-Benz approved car shampoo.
Carefully spray the vehicle with water and dry off with a leather cloth. Do not point the water jet directly into the air inlet grille.
When operating the vehicle in winter, remove all traces of road salt deposits carefully and as soon as possible.
