Glass cleaning - general
Special care should be taken to avoid scratching the glass. If it is cleaned at the same
time as the rest of the car, there is a possibility that particles of grit will cause fine
scratches. Flush off any mud on the glass when washing the body, but leave the final
cleaning and polishing until afterwards. Use Holden Glass Cleaner and wash each
section of glass in turn, making sure that the water, its container and the sponge are
quite clean and free from grit. Clean old linen cloth is better than new material for
polishing glass.
Windscreen
It is important that the windscreen be kept clean so that the wiper blades may be as
effective as possible. Old wiper blades can cause windscreen scratching and so should
be regularly inspected and replaced.
Abrasive cleaners should never be used to clean glass as they can cause scratches,
impairing night vision. After the windscreen has been cleaned with a wet sponge it
should be wiped over with a soft, lint free cloth or chamois.
It is recommended that Holden Optikleen be added to the windscreen washer reservoir.
Wiper blades
Oil and road scum thrown up on the windscreen will cause smearing when the wipers
are switched on, when the dirt is transferred onto the wiper blades. Many owners, whilst
they methodically clean the windscreen glass, omit to clean the wiper blades and
consequently smearing of the glass reappears immediately the wiper blades are used.
The blades can be cleaned by lifting them off the windscreen and cleaning with Holden
Optikleen and a clean cloth.
DO NOT OPERATE THE WIPER BLADES BY HAND AS THIS MAY DAMAGE THE
WIPER DRIVE MECHANISM
If the wiper blades are used to clean dust and dirt from the windscreen in dry conditions
always use the washer system first to wet the windscreen. Ensure that the windscreen
washer reservoir is not empty.
Should the wiper blades be frozen to the windscreen, they must be lifted off and freed
by hand before switching on the wipers.
Ventilation system intake
The intake area between the bonnet and windscreen may collect leaves, which will
impair air flow into the car.
It is recommended that this area be cleared of debris whenever you wash your car.
