The longer that deposits remain on the vehicle, the more the surface may be damaged. High temperatures such as those caused by sunlight increase the damaging effect.
Before washing, rinse off heavy deposits with plenty of water.
Stubborn deposits such as bird droppings or tree sap are best removed with plenty of water and a microfiber cloth.
Also, wash the underside of your vehicle once road salt stops being used for the season.
Pressure washers
When washing your vehicle with a pressure washer, always follow the operating instructions provided with the pressure washer. This is especially important in regard to the pressure and spraying distance. Do not aim the spray directly at the seals on the side windows, doors, lids or the sunroof or at tires, rubber hoses, insulating material, sensors or camera lenses. Keep a distance of at least 16 in (40 cm).
Do not remove snow and ice with a pressure washer.
Never use cone nozzles or high pressure nozzles.
The water temperature must not be above 140 ºF (60 ºC).
Automatic car washes
Spray off the vehicle before washing.
Make sure that the windows and roof are closed and the windshield wipers are off. Follow instructions from the car wash operator, especially if there are accessories attached to your vehicle.
If possible, use car washes that do not have brushes.
Washing by hand
Clean the vehicle starting from the top and working down using a soft sponge or cleaning brush.
Use solvent-free cleaning products.
Washing vehicles with matte finish paint by hand
To avoid damaging the paint when washing, first remove dust and large particles from your vehicle.
Insects, grease spots and fingerprints are best removed with a special cleaner for matte finish paint.
Apply the product using a microfiber cloth. To avoid damaging the paint surface, do not use too much pressure.
Rinse the vehicle thoroughly with water. Then clean using a neutral shampoo and a soft microfiber cloth.
Rinse the vehicle thoroughly again and let it air dry. Remove any water residue using a chamois.
WARNING
Note
For the sake of the environment
Only wash the vehicle in facilities specially designed for that purpose. This will reduce the risk of dirty water contaminated with oil from entering the sewer system.
