What is the best way to clean and old toy car?

I found a very old,valuable toy car in my loft. Its made by Dinky. I got most of the dust of with cotton bud but what can i use to get the dust out of all the nooks and crannys or to give it a better clean.|||use like a makeup brush and just shove it in there and twist it|||I would maybe try a can of air that you use to clean out computers and keyboards first. It will be less damaging than any other chemical.|||I would use a qtip and rubbing alcohol but make sure it doesn't stay wet.|||Q TIPS AND ALCHAHOL.|||Sonic jewelry cleaning system.
