Once I get the corn husks home, I remove all of the outer pieces and the dark green tops and discard them. I also remove and toss out the black, dried portion of the silks. It's not worth trying to clean off the dirt and pesticides. I'm left with clean silks and the inner green-yellow husks. My girls love the silks. I cut them up, just to ensure they won't be a choking hazard (they're probably fine at full length). Husks and silks store quite well in the fridge for several weeks.
