First read and observe the introductory information
and safety warnings
The longer substances such as insects, bird droppings, resinous tree sap, road dirt, industrial deposits, tar, soot or road salt and other corrosive 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. The underside of the vehicle should also be cleaned thoroughly and regularly.
Car washes
Please observe the signs on the automatic car wash. Before using an automatic car wash take the usual precautions, such as closing all windows and folding in the exterior mirrors, in order to avoid damage to the vehicle. You must consult the car wash operator if there are special parts on your vehicle such as spoilers, roof luggage carrier systems or radio aerials .
The paint is hard-wearing enough for the car to be generally washed in an automatic car wash. However, the effect on the paint depends to a large extent on the design of the car wash. Volkswagen recommends the use of car washes without brushes.
To remove any waxy residue from the windows and to stop wipers rubbing, please note the following .
Washing the car by hand
When washing by hand, first soften the dirt with plenty of water and rinse off as well as possible.
Then clean the vehicle with a soft sponge, a glove or a brush using only light pressure. Start with the roof and work from the top to the bottom. Use a shampoo for very stubborn dirt only.
The sponge or glove should be wrung out thoroughly at regular intervals.
Clean the wheels, sill panels etc. last. Use a different sponge for this purpose.
