How long does it take to detail a car?

This really depends on how dirty the car is as well a car’s size, and how thorough the clean is.
For a full interior and exterior detail, it takes an average of 1-2 hours. However, for a car that isn’t excessively dirty could take longer. If you were doing an inside and out of a caravan, with full interior vacuums and polish, this would take 5-8 hours.
