Mix Multi-Purpose Powdered Cleaner following the directions on the
container label.
Use suds only and apply with a clean sponge.
Don’t saturate
the material.
Don’t rub it roughly.

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.
0 Wipe with a clean cloth.
USING SOLVENFTTPE CLEANER ON
FABRlC
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.
0 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.

NOTICE.)

abrasives. -All cleaning agents should be flushed promptly and not allowed
to dry on the 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.
Pfinish Care
Occasional waxing or mild polishing of your Cadillac may be necessary to
remove residue from the paint finish. You can get
GM approved cleaning
products from your dealer. (See “Appearance Care and Materials” in the
Index.)
Your Cadillac has a “basecoat/clearcoat” paint finish. The clearcoat gives
more depth and gloss to the colored basecoat.
L
CAREAND CLEmING OF PltLAETON TOP
The cloth cover material used on the Cadillac Phaeton Top option is an
extremely durable material that will, with proper care, retain its
appearance for a long period
of time. The top can also be subjected to
commercial car wash equipment procedures and cleaning solutions
without adversely affecting the appearance
of the material.
Your phaeton top should be washed frequently with neutral soapsuds and
cold or lukewarm water and a soft-bristled brush. Rinse the top with
sufficient quantities
of clear water to remove all traces of soap. If the
cover has been allowed to get severely soiled and cannot be properly
cleaned with soap and water, a mild cleaning agent can be used, such as
G.M. Multipurpose Powdered Cleaner (G.M. Part No. 1050803). Rinse
the entire top with water; then apply the mild cleaner
on a small area
(approximately
two square feet). Scrub the area with a soft-bristled hand
