In all my vehicles I keep a small swiffer duster tucked in the pocket on the back of the passenger seat. It's within arms reach so I can just grab it and wipe as far as I can reach - dash, cluster, radio area. Recently I saw a tip to wipe the dash with a dryer sheet after dusting. I doubted it. My wife had some unscented ones in the laundry room so I gave my dash a light wipe with it and be darned if it works quite well. I seem to need the swiffer less often.
