Not as common as the drive-through locations, but typically attached to one of them. You find a car wash location with a couple of wash bays in which you can drive into them and do the car washing. Pros: Allows you to hand wash your car away from your home, and can get the vehicle a bit more clean than the drive-thru wash ones.

Professional Detailers - Mobile and Non-Mobile. The people we choose to use when we desire to have our vehicle looking better than what we ourselves could do. Most of the professional detailers have specific washing techniques they use and follow to prevent scuffs, swirls, and scratches. Such as the 2 bucket method, or the 1 bucket 8 towels/mitts. Pros: Most know how to do a safe and proper wash by hand, using either the 2 bucket method or the 6-8 towel method.
