Washing the vehicle by hand
Observe the legal requirements. For example, in a number of countries, washing by hand is permitted only in 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 chamois. 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.
