For best results:
• Do not wash the vehicle in strong sunlight. Let the vehicle
cool before washing.
• Do not use household soaps or detergents.
• Do not direct water hoses at full force around the door and
trunk lid seals.
• Do not use a brush on the car body as this will leave little
scratches.
Suggested washing method:
1. Fill two buckets with water. Add a mild neutral detergent, as
directed by the detergent manufacturer to one of the
buckets.
2. Use a hose to remove all dust and mud residue from the
vehicle. Don't use a strong jet, as this can rub grit over the
paint and scratch it.
3. Soak a large clean wash mitt or a soft clean sponge in the
soapy water, and begin applying it to the vehicle. Wash the
vehicle section by section, starting at the top. Circle around
the car several times, washing lower areas with each round.
Rinse the dirt out of the wash mitt or soft sponge in the
bucket with plain water frequently.
4. After one section is washed, rinse it with the hose before
moving on, don't let the soap dry on the paint as this can
stain it. Always keep the vehicle wet, this will prevent
droplets from drying on the paint and leaving water-spots.
5. Dry the car with a chamois leather before it air-dries.

Maintenance and Technical Data
Paint Work
Modern water based paints are much safer and more
environmentally friendly than solvent based paints. Water based
paints are however more susceptible to contamination and
marking by corrosive substances. The following list is not
exhaustive but does show the most common contaminants which
may adversely affect your paint work:
• Bird droppings,
• Antifreeze,
• Tree sap,
• Oils and greases,
• Insect remains.
Wash such substances from the vehicle using clean warm water
with vehicle shampoo at the earliest opportunity, especially in
sunny weather which can accelerate contamination.
Other groups of contaminants may be added to this list as
experience of water based paints and finishes increases.
Satin Paint
(Optional)
The Aston Martin new car warranty covers defects in
materials or workmanship of the paint work. The warranty
does NOT cover repairs to your satin or matt paint work
caused by negligence, lack of or improper maintenance such
as waxing or polishing the finish, environmental influences,
or improper repairs or damage that causes the satin finish to
become glossy.
