The longer substances like insects, bird droppings, resinous tree sap,
road dirt, industrial deposits, tar, soot or road salt and other aggressive
materials remain on the vehicle, the more damage they do to the paintwork.
High temperatures (for instance in strong sunlight) further intensify
the corrosive effect.
After the period when salt is put on the roads it is important to have
the underside of the vehicle washed thoroughly.
Automatic car washes
Before going through a car wash, be sure to take the usual precautions
such as closing the windows and sun roof. If the vehicle has special
accessories such as spoilers or a roof carrier or two-way radio
aerial, etc., it is advisable to consult the car wash operator.
It is best to use a car wash without revolving bristles if possible.
Washing your car with a high-pressure cleaner
When cleaning the vehicle with a high-pressure cleaner, always follow
the operating instructions for the equipment. This applies particularly
to the operating pressure and
the spraying distance. Do not
hold the spray nozzle too close to soft materials, such as rubber
hoses, seals or sensors
Link.
Do not use a nozzle that sprays the water out in a
direct stream or one that has
a rotating jet for forcing off
dirt.
Washing the car by hand
When washing the car by hand, use plenty of water to soften the
dirt first, and rinse off as well as possible.
Then clean the vehicle with a soft
sponge, glove or
brush, using only slight pressure.
You should start on the roof and work down. Special
car shampoo should only be used
for very persistent dirt. Use only solvent-free cleaning agents.
Rinse the sponge or glove thoroughly and often.
Wheels, sills and similar should be cleaned last. Use a second sponge
for this.
- Do not wash the vehicle with the ignition switched on – risk of accident.
- Do not clean the underside of the car or inside the wheel arches without protecting your hands and arms. You may cut yourself on sharp metal parts.
- Take care when washing the car during the winter: moisture and ice on the brakes may affect braking efficiency – this could cause an accident.
- Always take the key with you when leaving the vehicle - even if you only intend to be gone for a short time. This is especially important if children are left in the car. They might otherwise be able to start the engine or use power-operated equipment such as the electric windows - this could lead to injuries.
Caution!
- Do not wash the vehicle in direct sunlight – otherwise the paint can be damaged.
- Do not use insect sponges, or abrasive household sponges, etc. – they can damage the surfaces.
- The headlights should only be washed with water - do not wipe them with a dry cloth or sponge. It is best to use soapy water.
- Never wash tyres with a jet that sprays the water out in a direct stream. This could damage the tyres - even if the spray is kept at a distance and only used for a very short time.
- Compare the width of your vehicle with the available width when entering and driving through the car wash.
- Retract the exterior mirrors to avoid damage. Electrically retractable exterior mirrors* must NOT be folded in or out by hand. Always use the electrical power control.
For the sake of the environment
The car should only be washed in special wash bays. This prevents oily
water from getting into the public drains. In some districts, washing
vehicles anywhere else may be prohibited.
