The smaller, firmer brushes (like the white medium brush) are perfect for dusting air vents and the seams around buttons or trim. Perfect for cleaning air conditioning vents, around radio buttons and switches, door panel seams, and cup holders. Mist the brush lightly with an interior cleaner and agitate the dirt out of the crevices. Wipe with a microfiber towel immediately after. The softer, fluffier brushes (like the large black one) are ideal for gently dusting the instrument cluster, screens, and the dashboard without scratching them. Use a light, gentle sweeping motion. Don't press hard. For deep cleaning, spray your cleaner onto a microfiber cloth first, then use the brush to agitate. The stiffest brush (like the tan one) is great for cleaning around exterior badges/emblems, fuel filler door jambs, or for scrubbing heavier, sticky grime in interior cup holders and door pockets. For stubborn grime, use a targeted spray of interior cleaner and a bit more pressure than you would on the dash. Never use this stiffest brush on sensitive plastics or screens.
