Input: [header] How to clean car plastic [title] Vacuum the interior. [step] Before you begin, vacuum out your car to remove any debris. Your cleaning products will work much better if you vacuum before getting started. <sep> (A) To start, vacuum, just and use a suction tool. Where you vacuum will depend upon the make and model of your car, but you probably have to use either a microfiber upholstery brush or a square vacuum brush. (B) [substeps] Since cleaning the interior of cars like these can get complicated, it is good to use a vacuum cleaner. Clip on rubber, corrugated, and painted pieces of plastic on the outside of the car. (C) Using a soft brush attachment on the vacuum nozzle will help prevent scratching. [substeps] Remove the floor mats and shake them before you start vacuuming. (D) Use a soft vacuum for seats, window coverings, and anywhere else you see spray streaks. [substeps] A synthetic fiber vacuum made especially for car seats will not work best because it does not have to be vacuumed at all.
