I keep it in the trunk of my sports car to use before I put the cover on it in between washings, and after I leave it parked under a tree or somewhere where small leaves or dust etc fall on my car. It's also great after I take off the car cover to dust off the grey headcover dust that is inevitable after a few months with certain car covers. (I won't name names, but if you have one you'll know.) Highly recommend it.
