I love California dusters for keeping my car clean between washes.  For some reason this last one I received leaves a little bit of of a waxy residue on the car, but I'm guessing it'll disappear after I've picked up a bit more dust.  This wooden handle model is very nice; my last one was plastic but still lasted for years.  A few quick sweeps keeps saves me a fortune in car washes.  Definitely a must for anyone that likes keeping their car clean but doesn't want to hit the car wash all the time.
