Lexus GS300 1998 Owner's Manual page 454

Aluminum wheels: Use only a mild soap or neutral
detergent.
Urethane bumpers and side moldings: Wash carefully. Do
not scrub with abrasive cleaners. The bumper and side
molding faces are soft.
Road tar: Remove with turpentine or cleaners that are
marked safe for painted surfaces.
NOTICE
Do not use gasoline or strong solvents, which may be
toxic or cause damage.
3. Rinse thoroughly – dried soap can cause streaking. In hot
weather you may need to rinse each section right after you
wash it.
4. To prevent water spots, dry the vehicle using a clean soft
cotton towel. Do not rub or press hard – you might scratch the
paint.
Automatic car wash
Your vehicle may be washed in an automatic car wash, but
remember that the paint can be scratched by some type of
brushes, unfiltered washing water, or the washing process
itself. Scratching reduces paint durability and gloss,
especially on darker colors. The manager of the car wash
should be able to advise you whether the process is safe for
the paint on your vehicle.
Waxing your Lexus
Polishing and waxing is recommended to maintain the
original beauty of your Lexus' finish.
Once a month or if the vehicle does not repel water well, apply
wax.
1. Always wash and dry the vehicle before you begin waxing,
even if you are using a combined cleaner and wax.
2. Use a good quality polish and wax. If the finish has
become extremely weathered, use a car–cleaning polish,
followed by a separate wax. Carefully follow the
manufacturer's instructions and precautions. Be sure to
polish and wax the chrome trim as well as the paint.
3. Wax the vehicle again when water does not bead but
remains on the surface in large patches.
