Experts recommend detailing your vehicle every 4 to 6 months and no less than once or twice a year. That said, most experts recommend that your car be detailed at least every four to six months, that is, about two or three times a year. However, this recommendation is only a general rule. How often you choose to detail your car should depend on your car, what you use it for, and the type of person you are.
Having your car detailed is a routine that should be as normal as changing the oil, though not as often. The consensus on how often this should be done varies; some recommend a thorough detail once a year, while others recommend detailing it as an ongoing process of caring for your car.
