This video demonstrates how to clean the interior of your car. You will need to thoroughly vacuum your car. Vacuum all of the surfaces, the vents, air bag, crevices, etc. Next, clean your surfaces with a good cleaner and a microfiber cloth. Spray the cleaner on your towel. Wipe the surfaces with the wet side. Then, buff it with the dry side. Repeat in this manner throughout your car. You will need brushes of various types to dust all of the various surfaces. You will need brushes of different lengths and degree of coarseness. Make sure all dust has been removed, before you spray cleaners on them. Work in sprays with a leather brush, for your seats, before wiping them with a cloth. You may have to vacuum again, after cleaning surfaces, because cleaning will release trapped dirt.
