GMC 2009 Sierra - Manual (Page 413)

Instrument Panel, Vinyl, and
Other Plastic Surfaces
A soft cloth dampened with water may be used to
remove dust. If a more thorough cleaning is necessary,
a clean soft cloth dampened with a mild soap solution
can be used to gently remove dust and dirt. Never
use spot lifters or removers on plastic surfaces.
Many commercial cleaners and coatings that are sold
to preserve and protect soft plastic surfaces may
permanently change the appearance and feel of your
interior and are not recommended. Do not use silicone
or wax-based products, or those containing organic
solvents to clean your vehicle’s interior because
they can alter the appearance by increasing the
gloss in a non-uniform manner.
Some commercial products may increase gloss on
your instrument panel. The increase in gloss may
cause annoying reflections in the windshield and
even make it difficult to see through the windshield
under certain conditions.
Wood Panels
Use a clean cloth moistened in warm, soapy water
(use mild dish washing soap). Dry the wood immediately
with a clean cloth.
Care of Safety Belts
Keep belts clean and dry.
{ CAUTION:
Do not bleach or dye safety belts. If you do,
it may severely weaken them. In a crash,
they might not be able to provide adequate
protection. Clean safety belts only with mild
soap and lukewarm water.
