Keepin' it clean

I find I have this overwhelming urge to spray something liberally all over the inner workings of my distributor, to rinse away all that fine dust that seems to be a by-product of living out here on this 17 acres of dirt.
What product would satisfy this nagging desire?
All I know of is that stuff tyhey used to call "TV Tuner Cleaner" and I'm sure there is something more specific for this purpose.
Any thoughts?
