Skilful saloon sergeants begin by showering cars with water and care, scrubbing off bird droppings or eggs thrown by angry neighbours. While cleaning enables windscreens to shine once again, interiors also receive suction treatment to weed out crumbs and burgeoning ant colonies seeking to take over the world. Neglected tyre rims caked in mud and other non-shiny compounds enjoy a revitalisation, giving them a shine only seen on vehicle rims of rap stars. Last but not least, the polishing of surfaces leaves vehicles glistening under the sun but may blind oncoming drivers during the daytime. There is no extra charge for SUVs and MPVs, but owners of motorcycles or magic carpets should look elsewhere.
