well-ventilated area only. If you use

Vacuum and brush the area to remove
any loose dirt.

I NOTICE:
I
Be careful with a hair dryer or heat
lamp. You could scorch the fabric.
Wipe with a clean cloth.
Using Solvent-Type Cleaner 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 a solvent:
0
0 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 the
previous NOTICE.)
Fabric Protection
Your Corvette has upholstery and carpet
that has been treated with Scotchgard”
Fabric Protector, a 3M product.
Scotchgard
” 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, 1-800-642-6167).
Special Cleaning Problems
Greasy or oily stains:
Such as grease,
oil, butter, margarine, shoe polish, coffee
with cream, chewing gum, cosmetic
creams, vegetable oils, wax crayon, tar
and asphalt.
Carefully scrape
off excess stain.
Follow the solvent-type instructions
described earlier.
Shoe polish, wax crayon, tar and
asphalt will stain if left on a vehicle
