Exterior detailing is a type of car maintenance and care that focuses on keeping the outside of the vehicle clean, glossy, and protected. It typically involves washing the car's exterior surfaces using specialized tools and products that remove dirt, debris, and grime from the paintwork, wheels, tires, trim, and glass. Exterior detailing can also include chemical and mechanical decontamination processes to remove contaminants like iron particles and tar, as well as polishing and waxing to restore shine and protect the paint.
