MAJ NTE.'IANCE OF BODYWORX AND
UPHOlSTERY
It
is advisable
to
wash the
coachwork
of
the
car
with
an abundant
quantity of
water to remove all traces
of
dust, mud,
and
traffic
film.
Polish the
~ntwork
fre-
quentJy with
a good-quality
car
polish
which
is
free from
abrasive.
Wash
the chromium
parts frequently with
soap
and
warm
water, and when
the dirt bas been removed polish
the
surface
with a clean
d
ry cloth, o
r
a chamois-leather,
until bright. Neither metal polishes nor abrasives
of
any
sort
must
be used on chromium, but
a good-quality
metal
polish may
be used
on stainless-steel window
frames,
windshield
surrounds,
and radiator
grilles.
When
cleaning windshields it is
advisable to
use
IJKthylated spints (denatured alcohol)
to remove
tar
spots and other
stains.
It bas been
found
that the
use of
some silicon- and
wax-based polishes
for
this purpose
can be
detrimental to
the
windshield wiper
blades.
The
upholstery of
the car
should be cleaned
periodi·
cally
by
wiping O\'Cr with a damp
cloth.
Accumulations
of dirt,
if
left too
long,
eventually work
into
the pores of
the
leather,
giving
a
soiled
appearance. A little neutral
soap
may
be used, but
detergents,
caustic soaps, or spirits
of any kind must
not
be used.
When
necessary,
the hood cloth may be cleaned with
water applied with a
brush.
Soaps and detergents must
not be
used.
