Chevrolet Sonic Owner's Manual: Washing the Vehicle
To preserve the vehicle's finish, wash it often and out of direct sunlight.
Caution
Do not use petroleum-based, acidic, or abrasive cleaning agents as they can damage the vehicle's paint, metal, or plastic parts. If damage occurs, it would not be covered by the vehicle warranty. Approved cleaning products can be obtained from your dealer. Follow all manufacturer directions regarding correct product usage, necessary safety precautions, and appropriate disposal of any vehicle care product.

Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting.
