I would never use water, even a damp cloth, on leather. To clean the dust I simply use the Swiffer Duster meant for dusting in the home. Works great because it picks up the dust in hard to reach places, and you're not using water or any other household cleaner on the leather.
For deeper cleaning and conditioning I use Zaino Cleaner and Zaino Leather in a Bottle. Whatever you get just make sure it contains no silicone.
I agree with Rod to use a sunshade.
