I think we're talking two different things. My dealer subcontracts detailing work as well. Thats not unusual. I'm talking about the complementary wash dealers frequently do as part of service. They don't subcontract complementary washes due to the cost. It's typically done out back just before returning your car. I've found this to be a swirl mark source. As a minimum go back there and see what's being used on your car.
