Washing Your Vehicle The best way to preserve your vehicle's finish is to keep it clean by washing it often with lukewarm or cold water. Don't wash your vehicle i n the direct rays of the sun. Don't use strong soaps or chemical detergents. Use liquid hand, dish or car washing (mild detergent) soaps. Don't use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle. Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM approved cleaning products from your dealer. (See "Appearance Care and Materials" in the Index.) Your vehicle has c? "basecoat/clearcoat" paint finish. Theclearcoat gives mot-e depth and gloss to the colored basecoat.
