one wash mitt for the top of the vehicle
(roof, luggage compartment lid and
areas above the wheel arch line) and a
separate mitt for areas below the wheel
arch line.
NOTE: Do not clean the wheels with
these wash mitts.
NOTE: Do not allow the shampoo to dry,
it will leave streaks on the paint work.

Washing the Wheels
NOTE: Wash the wheels frequently, do
not allow brake dust to become
ingrained in the wheel rim finish.
Wash the wheels using warm water, a good
quality car shampoo and a wheel brush or
wash mitt that is used only on the wheels.
Apply polish to non-satin finished wheels to
assist in keeping them clean.
NOTE: Never apply polish to satin finish
wheels, this will result in localised glossy
patches on the surface of the wheel.
NOTE: Do not use acid based wheel
cleaners as these can damage the wheel
rim finish leading to corrosion.
NOTE: Ensure the brakes are fully dried
after the wheels have been cleaned
before the vehicle is stored.
Wiper Blades and Rubber Seals
Clean wiper blades and rubber seals using
warm water and a good quality car shampoo
only. Do not use petroleum or alcohol-based
cleaners.
Windscreen, Windows and Mirrors
Regularly clean all windows inside and out
using a window cleaning solution. An
automotive glass cleaner is recommended.
After washing the vehicle with car shampoo
containing wax, clean the outside of the
windscreen with glass cleaner. Do not use
abrasive cleaning compounds as mirror glass
is particularly susceptible to damage.
Underbody Cleaning
Salt used on roads to control snow and ice
during the winter can collect on the vehicle's
underbody, if this is not removed, corrosion
can occur. During the winter months,
regularly hose the underbody with water
paying particular attention to the wheel
arches and areas where dirt can accumulate.
