Generally, the painted
surfaces
can
be
kept
bright
by
washing
with
water
and mild soap, followed
by
a
rinse
with
water
and
drying
with
cloths
or
a chamois.
Harsh
or
abrasive
soaps
or
detergents
which
cause
corrosion
or
scratches
should never be used. Remove
stubborn
oil
and
grease
with a cloth moistened with .Stoddard solvent.
Waxing
is
unnecessary
to keep the painted
surfaces
bright.
However,
if
desired, the
airplane
may be waxed with a good automotive wax. A
heavier
coating of wax
on
the leading edges of the wings and
tail
and
on
the engine nose cap and
propeller
spinner
will help
reduce
the
abrasion
encountered in
these
areas.
When the
airplane
is
parked
outside
in
·cold
climates
and
it
is
neces-
sary
to
remove
ice before flight,
care
should be taken to
protect
the
paint-
ed
surfaces
during ice
removal
with
chemical
liquids.
A
50-50
solution
of
isopropyl alcohol and
water
will
satisfactorily
rem9ve
ice
accumulations
without
dam~ing
the paint. A solution _with
more
than
50%
alcohol
-
is
harmful and
should
be avoided. :While applying the
de-icing
solution,
keep
it
away
from
the windshield and cabin windows
since
.the
alcohol
will
attack the
plastic
and may
cause
it
to
craze.

ALUMINUM
SURFACES.
The
clad
aluminum
surfaces
of your
Cessna
may
be
washed
with
clear
water
to
remove
dirt;
oil
and
grease
may
be
removed
with
gasoline,
naphtha,
carbon
tetrachloride
or
other
non-alkaline
solvents.
Dulled
alu-
minum
surfaces
may
be
cleaned
effectively with an
aircraft
aluminum
polish.
After cleaning, and
periodically
thereafter,
waxing with a good
auto-
motive wax will
preserve
the
bright
appearance
and
retard
corrosion.
Regular waxing
is
.
especially
recommended
for
airplanes
operated
in
·
salt water
areas
as
~protection
against
corrosion.
