It is tree pollen. Probably will only happen for a few weeks then done. The duster will take it off but you will need to wash the duster after one or two of those wipes. Best, in my opinion, is to leave it until you can hose it off. Only a couple of weeks and the trees stop pollinating.
Can you cover the car? Then you will just have to lay the cover on the driveway and hose it off when you get home. Just take a garbage bag with you so when you roll up the cover you do not get that tree jizz in your trunk.
