Start cleaning your car by vacuuming the interior. It's best to remove floor mats and slide the seats to reach every nook and cranny. Use a crevice tool to remove dust and dirt from the seat crevices. To effectively vacuum the upholstered floor, a powerful vacuum cleaner is necessary, as handheld ones powered by the car's socket might not remove deeply embedded debris.

Continue the cleaning process from "top to bottom," and thoroughly clean the windows. Home remedies may work, but it's best to use dedicated car window cleaning solutions commonly used in auto detailing. These solutions are safe for seals and plastic elements and often come with anti-fogging additives. 

Avoid using popular spray-on products for cleaning plastics, as they leave a sticky layer that attracts dust. Professional detailing studios start by cleaning plastic surfaces with a microfiber cloth and an all-purpose cleaner (APC), followed by applying dressing. Dressing nourishes and darkens the plastic elements while protecting them from dust settling. 

For regular interior maintenance, ready-to-use universal detergents, known as interior cleaners, are sufficient. They work well for cleaning plastics, upholstery, and car windows. Unlike APC, they don't require dilution or rinsing with water. 

Additional cleaning accessories will be helpful for thorough cleaning. Brushes can be used to clean rough plastic surfaces, and detailing brushes and sponges can reach areas difficult to access with regular cloths. A soft brush can clean ventilation grilles, seals, buttons, or glove box hinges. 

High-gloss lacquered elements like "piano black" may require polishing, similar to the process used on the car's body or rims. Removing scratches from these surfaces is easier than polishing scratches on the car's body, but it requires skill. 

Steam cleaning can be used for hinges, door recesses, pedals, and other places with tough dirt.

When caring for elements like the steering wheel, use dedicated car cosmetics exclusively. Household cleaning agents could damage the clear protective layer (topcoat) and saturate the leather.

Not all elements can be cleaned mechanically, which is why ozone treatment is an excellent idea. An ozone generator eliminates mold, bacteria, fungi, viruses, and unpleasant odors, such as cigarette smoke or musty smell. During ozone treatment, close the car's doors and windows, and ensure there are no people, animals, or plants inside the vehicle.
