I've been using one of these for years and I'm on my second one. This duster works exceptionally well and lifts the dust without dragging it around. I will NOT make a filthy car that hasn't been washed in weeks or months look clean. You must either keep your car in a garage, or use a cover like I do, and dust it daily to keep it looking clean. If I wash, clay bar, and wax my car I can go two months or perhaps more without washing it again, as long as I keep it covered, dust daily, and wipe it down weekly with an instant detailer. The fibers are impregnated with a paraffin wax so don't just lay it on something if you don't want it to be stained because of the wax and dirt. Also, if there is condensation on the car it really renders the duster ineffective so make sure it's dry before using it.
