Service & Appearance Care
Cleaning the Inside of Your Vehjcle
Use a vacuum cleaner often to get rid of dust and loose dirt\
. Wipe vinyl with
a clean, damp cloth.
Your GM dealer has
two GM cleaners-a solvent-type spot lifter and a foam-type
powdered cleaner. They will clean normal spots and stains very \
well.
Here are some cleaning tips:
Always read the instructions on the cleaner label.
Clean up stains as soon as you can-before they set.
Use a clean cloth or sponge, and change to a clean area often. A soft
brush may be used
if stains are stubborn.
Use solvent-type cleaners in a well ventilated area only. If you use them,
don’t saturate the stained area.
If a ring forms after spot cleaning, clean the entire area immedi\
ately or it
will set.
Using Foam-Type CIeaner on Fabric
Vacuum and brush the area to remove any loose dirt.
Always clean a whole trim panel or section. Mask surrounding trim along
stitch or welt lines.
Mix Multi-Purpose Powdered Cleaner following the directions on t\
he
Use suds only and apply with a clean sponge.
container label.
Don’t saturate the material.
Don’t rub
it roughly.
As soon as you’ve cleaned the section, use a sponge to remove the
suds.
Rinse the section with a clean, wet sponge.
Wipe off what’s left with a slightly damp paper towel or cloth.
Then dry it immediately with an air hose, a hair dryer or a heat lamp.
NOTICE I
Be careful with a hair dryer or heat lamp. You could scorch the fabric

Using Solvent-Type CIeaner on Fabric
First, see if you have to use solvent-type cleaner at all. Some spots and
stains will clean
off better with just water and mild soap.
If you need to use it, then:
Gently scrape excess soil from the trim material with a clean, dull knife
or scraper. Use very little cleaner, light pressure and clean cloths
(preferably cheesecloth). Cleaning should start at the outside \
of the stain,
“feathering” toward the center. Keep changing
to a clean section of the
cloth
.
When you clean a stain from fabric, immediately dry the area with an air
hose, hair dryer, or heat lamp
to help prevent a cleaning ring. (See
previous NOTICE.)
Fabric Profection
Your vehicle has upholstery that has been treated with ScotchgardTM \
Fabric
Protector, a
3M product. ScotchgardTM protects fabrics by repelling oil and
water, which are the carriers
of most stains. Even with this protection, you
still need
to clean your upholstery often to keep it looking new.
Further information on cleaning is available by calling
1-800-433-3296 (in
Minnesota,
1-800-642-61 67).
Special Cleaning Problems
Greasy or Oily Stains: Like grease, oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic creams, vegetable oils, wax c\
rayon, tar
and asp ha1
t .
Carefully scrape off excess stain.
Then follow the solvent-type instructions above.
Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle
seat fabric. They should be removed as soon as possible. Be c\
areful, because the cleaner will dissolve them and may cause them
to bleed.
Non-Greasy Stains: Like catsup, coffee (black), egg, fruit, fruit juice, milk,
soft drinks, wine, vomit, urine and blood.
Carefully scrape off excess stain, then sponge the place with cool water.
If a stain remains, follow the foam-type instructions above.
If an odor lingers after cleaning vomit or urine, treat the area with a
watedbaking soda solution:
1 teaspoon (5 ml) of baking soda to 1 cup
(250 ml) of lukewarm water.
Finally, if needed, clean lightly with solvent-type cleaner.

Cleaning the Outside of the Windshield and Wiper Blades
If the windshield is not clear after using the windshield washer, or if the wiper
blade chatters when running, wax or other material may be on the blade or
windshield,
Clean the outside windshield with
GM Windshield Cleaner, Bon-Ami Powder@
(GM Part No. 1050011). The windshield is clean if beads do not form when
you rinse it with water.
Clean the blade by wiping vigorously with a cloth soaked in full strength
washer solvent. Then rinse the blade with water.
Wiper blades should be checked on a regular basis and replaced\
when worn.
Cleaning the Outside of Your Vehicle
The paint finish on your vehicle provides beauty, depth of color, gloss
retention and durability.
Washing Your Vehicle
The best way to preserve your vehicle’s finish is to keep it clean by washing
it often with lukewarm or cold water.
Don’t wash your vehicle in the direct rays
of the sun, Don’t use strong soaps
or chemical detergents. Use liquid hand, dish or car washing (non-detergent)
soaps. Don’t use cleaning agents that contain acid
or abrasives. All cleaning
agents should be flushed promptly and not allowed to dry on t\
he surface, or
they could stain. Dry the finish with a soft, clean chamois or a
100% cotton
towel to avoid surface scratches and water spotting.
High pressure vehicle washes may cause water to enter your vehicle.
Finish Care
Occasional waxing or mild polishing of your vehicle may be necessary to
remove residue from the paint finish. You can get GM approved cleaning
products from your dealer. (See “Appearance Care and Materia\
ls” in the
Index.)
Your vehicle has a “basecoatlclearcoat” paint finish. The clearcoat gives more
depth and
gloss to the colored basecoat.
Machine compounding
or aggressive polishing on a basecoatlctearcoat I f
paint finish may dull the finish or leave swirl marks.
