Air duct cleaning brushes. The dirtiest place in the interior of a car, after the mats, is of course the air duct nozzles. They have to constantly run air through them, and it is not always clean. That is why enough dust accumulates deep inside the air ducts. You can get it out with special small brushes, which are great for cleaning both air ducts and blinds in the apartment.
