Engine Cleaning
Prior to cleaning the engine
compartment make sure to protect
electrical components and connectors
from the intrusion of water or cleaning
agents.
Corrosion protection, such as MB
Anticorrosion Wax should be applied
to the engine compartment after every
engine cleaning. Before applying, all
control linkage bushings and joints
should be lubricated. The poly~V-belt
and all pulleys should be protected
from any wax.
Car Washing
Before washing your vehicle, remove
insect residues. MB Insect Remover is
recommended. Do not use hot water or
wash your car in direct sunlight. Use
only a mild car wash detergent, such as
MB Autoshampoo.
Thoroughly spray the car with a
diffused jet of water. Direct only a very
weak spray towards the
ventilation intake. Use plenty of water
and rinse the sponge and chamois
frequently.
Rinse with clear water and thoroughly
wipe dry with a chamois. Do not allow
cleaning agents to dry on the finish.
Before running the vehicle through an
automatic car wash, fold back the
outside mirrors to prevent them from
getting damaged.
If the vehicle has been run through an
automatic car wash -in particular one of
the older installations - rewipe the
recessed sections in the taillamps
(designed to prevent soiling) if
necessary. No solvents (fuels, thinners
etc.) must be used.
In the winter, thoroughly remove all
traces of road salt as soon as possible.
When washing the underbody, do not
forget to clean the inner sides of the
wheels.
Tar Stains
Quickly remove tar stains before they
dry and become more difficult to
remove. MB Tar Remover is
recommended.
Window Cleaning
Use a window cleaning solution on
all glass surfaces. MB Glass Cleaner
is recommended.
Wiper Blades
Clean the wiper blade rubber with a
clean cloth and detergent solution.
Replace blades twice a year; once
before and once after winter.
Headlamp Cleaning System
The condition of the wiper blades is
important for satisfactory cleaning of
the headlamp lenses. We therefore
recommend that the blades be
inspected regularly.
Replace damaged wiper blades.
