I personally would not recommend a califorina duster for your situation. They are effective at removing dust and leaving the paint clean but you greatly increase your risk of creating swirl marks. Cali Dusters are yarn that has been treated with parrifin wax, so you are dry wiping the dust against the paint.
A good option would be to team up a waterless wash product with some plush microfiber towels.
Waterless Washes are similar to a quick detailer but their job is provide an increased level of lubricity to safely remove moderate dirt, grit, and grime. Light dust will provide no problem.
Of the Waterless Wash products on the market, BLACKFIRE Wet Diamond Waterless Wash stands as a product that is really designed for the enthusiast, the guy who cares about maintaining a swirl free, high-gloss finish.
The secret of Wet Diamond Waterless Wash is that it uses the same polymers in as BLACKFIRE paint sealants. Everytime you mist Wet Diamond Waterless Wash onto the paint, thousands of Wet Diamond Polymers go to work. Some adhere to the grit and grime, others adhere to the paint, creating the barrier needed to avoid micro-scratching. As you lightly buff the finish with Wet Diamond Waterless Wash, the polymers on the paint begin to cure, adding a small layer of shine and protection to the paint.
