Wax-Treated Fibers: Most high-quality dusters (like the classic California Car Duster) feature cotton strands baked with a special paraffin wax. This wax acts like a magnet, picking up dust and holding it within the fibers.

Non-Scratch Design: The long, soft mop-head allows you to clean the car with minimal pressure, reducing the risk of "swirl marks" or micro-scratches on the clear coat.

Heavy-Duty Handles: Usually equipped with a high-impact plastic or wood handle, allowing you to reach across the roof or hood without leaning against the paint.

"The Dirtier, The Better": A unique trait of wax-treated dusters is that they actually become more effective as the fibers turn black with age.
