Cadillac 2012 CTS-V Owner's Manual page 438

To preserve the vehicle's finish,
wash it often and out of direct
sunlight.
Rinse the vehicle well, before
washing and after, to remove all
cleaning agents completely. If they
are allowed to dry on the surface,
they could stain.
Dry the finish with a soft, clean
chamois or an all-cotton towel to
avoid surface scratches and water
spotting.
Application of aftermarket clearcoat
sealant/wax materials is not
recommended. If painted surfaces
are damaged, see your dealer to
have the damage assessed and
repaired. Foreign materials such as
calcium chloride and other salts, ice
melting agents, road oil and tar,
tree sap, bird droppings, chemicals
from industrial chimneys, etc.,
can damage the vehicle's finish if
they remain on painted surfaces.
Wash the vehicle as soon as
possible. If necessary, use
non-abrasive cleaners that are
marked safe for painted surfaces
to remove foreign matter.
Occasional hand waxing or mild
polishing should be done to
remove residue from the paint finish.
See your dealer for approved
cleaning products.
