See, here’s the problem, at any hand car wash it doesn’t matter if they take great care with yours or any car, the problem is they use the same batch of mitts over and over again all day long. So all it takes is 1 good muddy vehicle to come through and soil up a couple or all the mitts and they get tossed right back into their big bucket with soapy water where they grab them from and those dirty mitts get re-used and will cause scratches on your paint. So the “great care” is actually sort of meaningless because you can take all the care in the world but if you’re working with dirty mitts they’re not going to be all that safe to begin with.
And I don’t know of any car wash that would go out of their way to only use the several mitts on 1 vehicle and rotate freshly washed mitts for the next… That would be too costly and time consuming to be washing mitts all day.
[some car washes actually do have a process in place that’s supposed to help wash the wash media as they toss it back in and re use it, but it’s more of a gentle swishing than an actual washing. 1 good muddy vehicle can turn that water into a swamp and that’s as good as it gets until the next time they decide to drain and refill that large machine]
Yea they “hand wash” your car, but that’s where the hands on part ends, because after that 1st. stage of the process it gets driven onto a track that gets pulled by a chain in order to go through the rinse, spray wax/foam, then rinse again, and finally high pressure air dried and finally comes out the other side of the tunnel where an employee starts the car and parks it for another employee to spot check it and clean the windows and earn his tip and hand you your keys once he’s all done.
