Maintenance, Car Care

139

Door, roof, lid and window seals

f Wash dirt (e.g. abrasion, dust, road salts) from

all seals regularly using warm soapy water. Do

not use any chemical cleaning agents or sol-

vents.

In order to prevent damage to the anti-fric-

tion coating, all seals around the doors, side

windows, and roof panels must not be treated

with car care products.

Headlights, lights, plastic rear windows,

interior and exterior plastic parts

f Only use clean water and a little dishwasher de-

tergent to clean plastic parts and surfaces.

Do not clean when dry.

Use a soft sponge or a soft, lint-free cloth. Gen-

tly wipe the surface without applying too much

pressure.

The Porsche inside window cleaner is also suit-

able for cleaning plastic surfaces. Follow the

cleaning instructions on the container.

Never use other chemical cleaners or

solvents.

f Rinse cleaned surfaces with clear water.

Light alloy wheels

Pitting may occur if metallic particles which cause

contact corrosion (e.g. brass or copper in brake

dust) are allowed to remain on the light alloy

wheels for too long.
f If possible, wash the wheels with a sponge or

wash brush about every two weeks. In areas

where salt is spread on winter roads or there is

a lot of airborne industrial dust, it is best to

clean the wheels weekly.

The Porsche Light Alloy Wheel Cleaner

(ph-value 9.5) can be used for this pur-

pose.

If the ph-value of the detergent is incor-

rect, the protective coating on the wheels

will be destroyed.

Polishes which dissolve oxides, such as those

frequently used for other metals, or abrasive

tools or agents are unsuitable because they

break down the oxide film of the protective

coating and will cause discoloration of the

wheel.
f Every three months, after cleaning, coat the

wheels with a car wax or non-corrosive grease

(petroleum jelly).

Using a clean cloth thoroughly rub the grease

into the surface.
