my experience is that unless you get some really torrential rain, it's not enough to clean the sand/dust/grime

Rain usually just cakes the dirt. Unless it's a downpour, it doesn't move with enough velocity or volume to remove the dirt. So the dirt just gets damp, maybe moves a few cm with gravity, then dries as a mud cake.
