To clean the interior of your car, start by removing all the trash and extraneous items. Moisten a rag with household or glass cleaner and wipe down the dashboard area, steering wheel, and center console. Next, remove the floor mats, vacuum them, then vacuum the car’s interior from top to bottom. Attempt to pick up any dust or debris on the dash. Next, take a soft micro fiber cloth, dipped in water, to wipe down your dash. If the interior of your car is particularly grimy, fill a bowl with warm water and mild soap. Use this to wipe the dashboard, steering wheel, hand brake, and interior plastic of your vehicle.
