Car wash soap and water. If it's really bad, I'll drape a wet towel over the windscreen for an hour and then wipe it up. The nasty stuff will usually soften up and come right off. Once or twice a summer I'll give it (and the entire bike) a shot of Original Bike Spirits "Spray Cleaner and Polish" (aka "Honda Spray Polish"), or Plexus if I have any.
