10-88 Vehicle Care
Leather/Leatherette
Leather, and lighter colored leather
in particular, will need more frequent
cleaning to prevent the buildup of
dust, dirt, and colors transferred
from other items so that these do
not become permanent stains.
To remove dust, a soft cloth
dampened with water can
be used. If a more thorough
cleaning is necessary, a soft cloth
dampened with a mild soap solution
can be used. Your dealer has a GM
approved leather cleaner available
that provides superior cleaning
performance when used regularly
on finished automotive leathers.
Allow the leather to dry naturally.
Do not use heat, steam, spot
lifters or spot removers, or shoe
polish on leather. Many commercial
leather cleaners and coatings that
are sold to preserve and protect
leather may permanently change
the appearance and feel of the
leather and are not recommended.
Do not use silicone or wax-based
products, or those containing
organic solvents to clean the
interior because they can alter
the appearance by increasing the
gloss in a non-uniform manner.
Instrument Panel, Vinyl and
other Plastic Surfaces
To remove dust, a soft cloth
dampened with water can be
used. 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 the interior
and are not recommended. Do not
use silicone or wax-based products,
or those containing organic solvents
to clean the interior because
they can alter the appearance
by increasing the gloss in a
non-uniform manner.
