A complete detail, interior and exterior, of an average-sized car usually takes me between three and four hours. This process usually takes 2 to 4 hours. It depends on how broken the car is. It takes about 15 hours over 2 days to do this.
The details of the car take between 2.5 and 10 hours, depending on the retailer, how clean your car is and what washing package you choose. Quality retailers take 5 to 10 hours, while a quantity retailer takes 2.5 hours or less to get the job done. A detail will last 4 to 8 weeks. Yes, I usually go slowly and take my time, I don't try much, so I'll fix my interior until I'm satisfied, I'll wash the truck and put it in clay, then the next job to make my exterior beautiful.
And cleaning the exterior is a multi-step process that involves washing and drying, polishing and sealing. As for detailing the exterior, the car must be washed with a prefilter and shampoo to remove persistent dirt. For a brief detail, I also like to clean the outer glass with a specialized good quality window cleaner.
