MAINTENANCE AND ADJUSTMENTSPAINT MAINTENANCE
To remove heavy concentrations of road dirt and
grime, it is recommended that the car be washed
using an automotive shampoo or mild soap, and cold
to lukewarm water. Use of harsh soaps or detergents
is not advised. In areas where salt is used on the
roads during the winter months, more frequentwashing is recommended.
Use of cleaners and polishes are required if no high
luster is obtainable by waxing. To protect the paint
finish, sparingly apply several coats of wax. Each
coat should be thoroughly rubbed to remove any
surplus wax.
Once the car is properly waxed, road dirt may easily
be removed by use of cold to lukewarm water and a
sponge. Dry by use of a chamois.
CHROME MAINTENANCE
Chrome parts should be washed with water and a
mild detergent. If rust or salt corrosion should ap-
pear, they may be removed with Buick Rust Eraser
or equivalent. Do not use scouring powders or stiff
brushes.STAIN REMOVAL
Before attempting to remove spots or stains from
upholstery fabrics, determine as accurately as possi-
ble: (1) Nature and age of the spot or stain. (2) The
affect of stain removing agents on the color, struc-
ture and general appearance of the fabric.
For best results, stains should be removed from
upholstery as soon as possible after they have been
made. If they are allowed to stand for some time,
they often become set, and removal becomes more
diffxult and frequently impossible.
There are three basic types of acceptable’ cleaners
available to car owners: (1) Volatile cleaners, (2) Syn-
thetic detergents, (3) Neutral soap (non-alkaline).
The volatile cleaners are recommended since they
have great solvent powers for grease, oils and general
road grime. Synthetic detergents generally loosen
stains satisfactorily, however, the use of improper
type detergents (containing bleach) involves risk of
damage to the color or finish of fabrics.
Precautions For Cleaning FabricsDo not use laundry soap or detergents containing
bleaches. The use of these agents tends to weaken
fabric and to change its color. Do
not use too much
cleaning fluid. Some interior trim assemblies are pad-

fabric to dry thoroughly; then rub lightly with a
clean cloth dipped in a volatile cleaner. This is the
only further treatment recommended.
Soap and water are not recommended since they will
probably set the stain and cause a permanent dis-
coloration. Drying the fabric by means of heat (such
as the use of an iron) is not recommended.
6. Grease and 02 If grease has been spilled on the
material, as much as possible should be remove by
scraping with a dull knife or spatula before further
treatment is attempted.
Grease and oil stains may be removed by rubbing
lightly with a clean cloth saturated with a volatile
cleaner. Be sure all motions are toward the center of
the stained area to decrease the possibility of spread-
ing the stain.
7. Ice Cream. The same procedure is recommended
for the removal of ice cream stains as that used in
removing fruit stains.
If the stain is persistent, rubbing the spot with a cloth
wet with soap suds (mild neutral soap) may be used
to some advantage after the initial treatment with hot
water. This soap treatment should be followed with
a rinsing, by rubbing with a clean cloth wet with cold
water. After this dries, rubbing lightly with a cloth
wet with volatile cleaner will clear up the last of the
stain, by removing fatty or oily matter.
8.Vomit. Sponge with a clean cloth, dipped in clear
cold water. After most of the stain has been removed
in this way wash lightly with soap (mild neutral),
using a clean cloth and lukewarm water. Then rub
with another clean cloth dipped in cold water. If any
of the stain remains after this treatment, gently rub
clean with a cloth moistened with a volatile cleaner.

9. Shoe Polish and Dressings. On types of shoe
dressing which contain starch or dextrine or some
water soluble vehicle, allow the polish to dry; then
brush the spot vigorously with a brush. This will
probably be all the treatment that is necessary. If
further treatment is required moisten the spot with
cold water and after it has dried, repeat the brushing
operation.
Paste or wax type shoe polishes may require using a
volatile cleaner. Rub the stain gently with a cloth wet
with a volatile cleaner until the polish is removed.
Use
;a clean portion of the cloth for each rubbing
operation and rub the stained area from outside to
center.
10. Tar. Moisten the spot lightly with a volatile
cleaner, and then remove as much of the tar as possi-
ble with a dull knife. Follow this operation by rub-
bing the spot lightly with a cloth wet with the cleaner
until the stain is removed.
II. .X&e. Sponge the stain with a clean cloth satu-
rated with soap suds (mild neutral soap) and rinse
well by rubbing the stain with a clean cloth dipped
in cold water. Then saturate a clean cloth with a
solution of one part household ammonia water and
five parts water. Apply the cloth to the stain and
allow solution to remain on affected area for one
minute; then rinse by rubbing with a clean wet cloth.
I,?.
L,ipslick. The compositions of different brands of
lipsticks vary, making the stains very
diff%cult to
remove. In some instances a volatile cleaner may
remove the stain. If some stain remains after re-
peated applications of the volatile cleaner, it is best
to leave it rather thari try other measures.
