Before you bring your car in for detailing, there are a few things you should do to prepare.   First, make sure to remove any personal belongings from the car and clean out any trash or debris. You don't want the detailers to have to work around clutter!   Additionally, give your car a quick wash before bringing it in so that the detailers can focus on deep cleaning rather than surface dirt.   Finally, be prepared to leave your car at the detailing shop for several hours, as the process can take some time.   By following these steps, you'll help ensure that your car gets the best possible treatment during its detailing appointment.
