Road spray is a dirty mist of contaminants in the air, thrown up by a vehicle driving over the road. Road spray is partly the cause for traffic film and can cause dirt and grime, even when the weather has been dry and there is no obvious origin for dirt on a vehicle.
A traffic film is the term used to describe the fine layer of contaminants that cover a vehicle that has been used. The very film layer of contaminants lie on top of the car as a grey-ish film. Washing alone might not always be enough to fully remove this film.
