An interior view of a self-service car wash bay in Madan, Bulgaria, depicts a silver Skoda station wagon covered in vibrant pink cleaning foam. The vehicle is positioned centrally within the concrete bay, facing slightly towards the right. Its front license plate, partially obscured by foam, displays "CP13XXBB", indicating a Bulgarian registration from the Smolyan province. The floor of the bay is wet and coated with the same pink foam, showing areas where it has started to drain. The walls of the bay are primarily concrete, with two large informational banners mounted. The left banner features an orange background with a large numeral "4" and Bulgarian text detailing wash programs, including illustrations of a car being cleaned. The right banner is black with a large numeral "3" and similar Bulgarian text and graphics. Overhead, exposed concrete ceilings with conduits are visible, from which a blue and a red hose, likely for water and foam application, hang. A black bucket and a pressure washer wand are situated against the left wall. No individuals are present in the scene. The lighting is uniform, suggesting artificial illumination within the enclosed bay.
