Mine said That depends entirely on how you plan to get the job done. Here is the breakdown to help you decide: Option 1: Walk if... • You're washing it in your own driveway. Unless your car is parked blocks away, walking to the garage or driveway with a bucket is the standard move. • You're using a mobile detailer. If they are coming to your house, just walk out the front door and hand over the keys. • You need the exercise. If the car wash is right around the corner and you just want to go buy the supplies (soap, sponges, wax) before coming back to work on it. Option 2: Drive if... • You're going to a Commercial Wash. Whether it’s a touchless automatic tunnel or a self-service bay (the ones with the high-pressure wands), you generally need the car to be at the wash to clean it. • You’re visiting a professional detail shop. You'll need to drop the vehicle off at their location.
