PREVENTIVE MAINTENANCE
• Trees are also likely to attract birds. Bird droppings have a high
acid content and will damage a freshly painted surface. Droppings
should be washed off as soon as possible.
•
Try to avoid spilling petrol, oil, anti-freeze, transmission fluid, brake
fluid and windscreen solvent on the new finish. If this happens wash
it off immediately.
• If the vehicle is to be stored, avoid using non-breathing covers on
finishes under 30 days old.
Wash frequently to remove grime and caustic deposits which could stain
the finish. Use cool or lukewarm water. A mild soap may be used. Avoid
washing in bright sunlight. Road tar can be removed with a special
commercial tar remover or mineral spirits. Waxing offers added protection
against staining and oxidation. Wait approximately 90 days after date of
manufacture before waxing to give the finish a chance to cure. Do not
wax in hot sun. If a buffing machine is used, take care not to friction-burn
the paint.
Aluminium and Chrome Surfaces
Aluminium wheels and bumpers can be cleaned with warm water. Tar
remover will take off heavy deposits of road grime. For added appearance,
wipe aluminium surfaces dry after washing to prevent spotting. Under
corrosive conditions such as driving on salted roads, clean aluminium pans
with steam or high-pressure water from a hose. A mild soap solution will
help. Rinse thoroughly.
Chrome surfaces are best cleaned with fresh water. Wipe dry to preserve
lustre. Light rust can be successfully removed with any commercial chrome
cleaner. After cleaning, wax flat surfaces and apply a thin coat of rust
preventive lubricant around bolts or other fasteners.
Interior
Vinyl upholstery and lining should be wiped clean with any good grade
commercial vinyl upholstery cleaner. DO NOT use chemicals such as
acetone or lacquer thinner. Fabric uphols tery can be cleaned with
upholstery shampoo specially formulated for this purpose. Follow
instructions on the container.
Cleaning of Cabin Trim
Aside from its classic aesthetic appearance, one of the features of the vinyl
trim used inside all Kenworth cabs is the material’s ease of maintenance.
The vinyl offers exceptional service life if given proper care.
