Unless you are doing ha d washes at home from time to time, brushless car washes never get your vehicle clean. There is always a film of dirt left on it. Don't care if you have ceramic coating or not. And wiping it down to dry after the fact, without removing the dirt left behind, is just as bad as using a car wash with the spinning or hanging brushes.
100% true. I pre-soak/spray down my truck with ONR and brush my wheels prior to hitting the touchless…. And use a leaf blower to dry off the remainder of the water that the blower dryers don’t get.
Yes…no where near as good hand wash.
But way better than a spinning brush with who knows what in the brushes, when they were cleaned…IF they’ve been cleaned.
I do handwash when weather permits. Not practical right about now in single digit temps.
I’ve tried 3-4 different touchless near me…and they don’t do as nearly good of a job as hand. But it’s quick and easy if it’s not too dirty. I hit it with some ceramic boost every few washes as well. I forgot how tough It is to keep dark clean looking…damn worth it when it’s clean though.
