The cars are dusty and I want to clean them, but am afraid I might do more damage to the paint and lettering. Could you tell me how I can safely wash these off or if it is safe to use a cleaner and water on them with possibly a q tip to get in the little corners and areas?

hello Susan. Don't use cleaner. If they are dusty, use a soft brush to get rid of the dust. I suggest that you leave them at that.
