Car Washing Techniques/Location
After the proper equipment has been gathered, the vehicle needs to be in a proper location (preferably in a shaded area, away from direct sunlight). A flat, dry, and clean surface such as a driveway or parking lot is prime; however, a gravel lot that is relatively clean will suffice. If neither are accessible, surfaces such as grass or dirt will work; however, mud may splash onto the vehicle when the hose is aimed at the tires. If the vehicle is washed on grass or dirt then the vehicle should be left until the ground and vehicle are both dry before the vehicle is moved.
