The vehicle should be washed as soon as it becomes dirty. This makes the vehicle
easier to clean because dirt does not attach as strongly. It also reduces the risk
of scratches and keeps the vehicle looking new. Wash the vehicle in a car wash or
garage with an oil separator and use car washing detergent...
