Washing
Wash the vehicle thoroughly with plenty of water and a soft sponge. Use a solution of clean, lukewarm water (never hot) and mild soap, car-specific soap or household liquid dish detergent.
WARNING
- Do not choose a car wash that uses a detergent containing acid.
Some car washes, especially those without brushes (touchless), use a detergent that contains acid. Acids can react with certain plastic components of the vehicle and cause cracks. These cracks may affect the appearance of the components and impair their function. Always ask the car wash operator whether an acid-based detergent is used.
Rinse the vehicle thoroughly with clean water.
Road salt particularly affects the inner door sills, door seals and door folds, the hinges, and the hood. Therefore, these areas must be washed regularly.
Make sure the drain holes at the lower edge of the doors are not blocked. Wash the underside of the body and the wheel wells with a water jet to loosen mud buildup and remove all traces of road salt.
A damp chamois may be used to wipe the body and prevent water spots from forming.
