GMC Chevrolet Silverado 2500HD 2021 Owner's Manual page 380

Use cleaners specifically designed for the
surfaces being cleaned to prevent
permanent damage. Apply cleaners directly
to the cleaning cloth. Do not spray cleaners
on any switches or controls. Remove
cleaners quickly.
Before using cleaners, read and follow all
safety instructions on the label. While
cleaning the interior, open the doors and
windows to get proper ventilation.
To prevent damage, do not clean the
interior using the following cleaners or
techniques:
Never use a razor or any other sharp
object to remove soil from any interior
surface.
Never use a brush with stiff bristles.
Never rub any surface aggressively or
with too much pressure.
Do not use laundry detergents or
dishwashing soaps with degreasers. For
liquid cleaners, use approximately
20 drops per 3.8 L (1 gal) of water.
A concentrated soap solution will create
streaks and attract dirt. Do not use
solutions that contain strong or
caustic soap.
Do not heavily saturate the upholstery
when cleaning.
Do not use solvents or cleaners containing
solvents.
Interior Glass
To clean, use a terry cloth fabric dampened
with water. Wipe droplets left behind with a
clean dry cloth. If necessary, use a
commercial glass cleaner after cleaning with
plain water.
Caution
To prevent scratching, never use abrasive
cleaners on automotive glass. Abrasive
cleaners or aggressive cleaning may
damage the rear window defogger.
Cleaning the windshield with water during
the first three to six months of ownership
will reduce tendency to fog.
Speaker Covers
Vacuum around a speaker cover gently, so
that the speaker will not be damaged. Clean
spots with water and mild soap.
Vehicle Care
Coated Moldings
Coated moldings should be cleaned.
When lightly soiled, wipe with a sponge
or soft, lint-free cloth dampened with
water.
When heavily soiled, use warm soapy
water.
Fabric/Carpet/Suede
Start by vacuuming the surface using a soft
brush attachment. If a rotating vacuum
brush attachment is being used, only use it
on the floor carpet. Before cleaning, gently
remove as much of the soil as possible:
Gently blot liquids with a paper towel.
Continue blotting until no more soil can
be removed.
For solid soils, remove as much as
possible prior to vacuuming.
To clean:
1. Saturate a clean, lint-free colorfast cloth
with water. Microfiber cloth is
recommended to prevent lint transfer to
the fabric or carpet.
2. Remove excess moisture by gently
wringing until water does not drip from
the cleaning cloth.
